Sudan or the Sudan (; Arabic: السودان as-Sūdān), officially the Republic of the Sudan (Arabic: جمهورية السودان Jumhūriyyat as-Sūdān), is a country in Northeast Africa.
From the late 11th/12th century, Makuria's capital Dongola was in decline, and Alodia's capital declined in the 12th century as well. In the 14th and 15th centuries Bedouin tribes overran most of Sudan, migrating to the Butana, the Gezira, Kordofan and Darfur. In 1365 a civil war forced the Makurian court to flee to Gebel Adda in Lower Nubia, while Dongola was destroyed and left to the Arabs. Afterwards Makuria continued to exist only as a petty kingdom. After the prosperous reign of king Joel (fl. 1463–1484) Makuria probably collapsed. To the south, the kingdom of Alodia fell to either the Arabs, commanded by tribal leader Abdallah Jamma, or the Funj, an African people originating from the south. Datings range from the 9th century after the Hijra (c. 1396–1494), the late 15th century, 1504 to 1509. An alodian rump state might have survived in the form of the kingdom of Fazughli, lasting until 1685.
In 1504 the Funj are recorded to have founded the Kingdom of Sennar, in which Abdallah Jamma's realm was incorporated. By 1523, when Jewish traveller David Reubeni visited Sudan, the Funj state already extended as far north as Dongola. Meanwhile, Islam began to be preached on the Nile by Sufi holymen who settled there in the 15th and 16th centuries and by David Reubeni's visit king Amara Dunqas, previously a Pagan or nominal Christian, was recorded to be Muslim. However, the Funj would retain un-Islamic customs like the divine kingship or the consummation of alcohol until the 18th century. Sudanese folk Islam preserved many rituals stemming from Christian traditions until the recent past.
Soon the Funj came in conflict with the Ottomans, who had occupied Suakin around 1526 and eventually pushed south along the Nile, reaching the third Nile cataract area in 1583/1584. A subsequent Ottoman attempt to capture Dongola was repelled by the Funj in 1585. Afterwards, Hannik, located just south of the third cataract, would mark the border between the two states. The aftermath of the Ottoman invasion saw the attempted usurpation of Ajib, a minor king of northern Nubia. While the Funj eventually killed him in 1611/1612 his successors, the Abdallab, were granted to govern everything north of the confluence of Blue and White Niles with considerable autonomy.
During the 17th century the Funj state reached its widest extent, but in the following century it began to decline. A coup in 1718 brought a dynastic change, while another one in 1761–1762 resulted in the Hamaj regency, where the Hamaj (a people from the Ethiopian borderlands) effectively ruled while the Funj sultans were their mere puppets. Shortly afterwards the sultanate began to fragment; by the early 19th century it was essentially restricted to the Gezira.
West of the Nile, in Darfur, the Islamic period saw at first the rise of the Tunjur kingdom, which replaced the old Daju kingdom in the 15th century and extended as far west as Wadai. The Tunjur people were probably Arabised Berbers and, their ruling elite at least, Muslims. In the 17th century the Tunjur were driven from power by the Fur Keira sultanate. The Keira state, nominally Muslim since the reign of Sulayman Solong (r. c. 1660–1680), was initially a small kingdom in northern Jebel Marra, but expanded west- and northwards in the early 18th century and eastwards under the rule of Muhammad Tayrab (r. 1751–1786), peaking in the conquest of Kordofan in 1785. The apogee of this empire, now roughly the size of present-day Nigeria, would last until 1821.
In 1821, the Ottoman ruler of Egypt, Muhammad Ali of Egypt, had invaded and conquered northern Sudan. Although technically the Vali of Egypt under the Ottoman Empire, Muhammad Ali styled himself as Khedive of a virtually independent Egypt. Seeking to add Sudan to his domains, he sent his third son Ismail (not to be confused with Isma'il Pasha mentioned later) to conquer the country, and subsequently incorporate it into Egypt. With the exception of the Shaiqiya and the Darfur sultanate in Kordofan, he was met without resistance. The Egyptian policy of conquest was expanded and intensified by Ibrahim Pasha's son, Isma'il, under whose reign most of the remainder of modern-day Sudan was conquered.
The Egyptian authorities made significant improvements to the Sudanese infrastructure (mainly in the north), especially with regard to irrigation and cotton production. In 1879, the Great Powers forced the removal of Ismail and established his son Tewfik Pasha in his place. Tewfik's corruption and mismanagement resulted in the 'Urabi revolt, which threatened the Khedive's survival. Tewfik appealed for help to the British, who subsequently occupied Egypt in 1882. Sudan was left in the hands of the Khedivial government, and the mismanagement and corruption of its officials.
From his announcement of the Mahdiyya in June 1881 until the fall of Khartoum in January 1885, Muhammad Ahmad led a successful military campaign against the Turco-Egyptian government of the Sudan, known as the Turkiyah. Muhammad Ahmad died on 22 June 1885, a mere six months after the conquest of Khartoum. After a power struggle amongst his deputies, Abdallahi ibn Muhammad, with the help primarily of the Baggara of western Sudan, overcame the opposition of the others and emerged as unchallenged leader of the Mahdiyah. After consolidating his power, Abdallahi ibn Muhammad assumed the title of Khalifa (successor) of the Mahdi, instituted an administration, and appointed Ansar (who were usually Baggara) as emirs over each of the several provinces.
Regional relations remained tense throughout much of the Mahdiyah period, largely because of the Khalifa's brutal methods to extend his rule throughout the country. In 1887, a 60,000-man Ansar army invaded Ethiopia, penetrating as far as Gondar. In March 1889, king Yohannes IV of Ethiopia marched on Metemma; however, after Yohannes fell in battle, the Ethiopian forces withdrew. Abd ar Rahman an Nujumi, the Khalifa's general, attempted an invasion of Egypt in 1889, but British-led Egyptian troops defeated the Ansar at Tushkah. The failure of the Egyptian invasion broke the spell of the Ansar's invincibility. The Belgians prevented the Mahdi's men from conquering Equatoria, and in 1893, the Italians repelled an Ansar attack at Agordat (in Eritrea) and forced the Ansar to withdraw from Ethiopia.
In the 1890s, the British sought to re-establish their control over Sudan, once more officially in the name of the Egyptian Khedive, but in actuality treating the country as a British colony. By the early 1890s, British, French and Belgian claims had converged at the Nile headwaters. Britain feared that the other powers would take advantage of Sudan's instability to acquire territory previously annexed to Egypt. Apart from these political considerations, Britain wanted to establish control over the Nile to safeguard a planned irrigation dam at Aswan. Herbert Kitchener led military campaigns against the Mahdist Sudan from 1896 to 1898. Kitchener's campaigns culminated in a decisive victory in the Battle of Omdurman on 2 September 1898.
In 1899, Britain and Egypt reached an agreement under which Sudan was run by a governor-general appointed by Egypt with British consent. In reality, Sudan was effectively administered as a Crown colony. The British were keen to reverse the process, started under Muhammad Ali Pasha, of uniting the Nile Valley under Egyptian leadership and sought to frustrate all efforts aimed at further uniting the two countries.
Under the Delimitation, Sudan's border with Abyssinia was contested by raiding tribesmen trading slaves, breaching boundaries of the law. In 1905 Local chieftain Sultan Yambio reluctant to the end gave up the struggle with British forces that had occupied the Kordofan region, finally ending the lawlessness. The continued British administration of Sudan fuelled an increasingly strident nationalist backlash, with Egyptian nationalist leaders determined to force Britain to recognise a single independent union of Egypt and Sudan. With a formal end to Ottoman rule in 1914, Sir Reginald Wingate was sent that December to occupy Sudan as the new Military Governor. Hussein Kamel was declared Sultan of Egypt and Sudan, as was his brother and successor, Fuad I. They continued upon their insistence of a single Egyptian-Sudanese state even when the Sultanate of Egypt was retitled as the Kingdom of Egypt and Sudan, but it was Saad Zaghloul who continued to be frustrated in the ambitions until his death in 1927.
The Sudanese Government was directly involved militarily in the East African Campaign. Formed in 1925, the Sudan Defence Force played an active part in responding to incursions early in World War Two. Italian troops occupied Kassala and other border areas from Italian Somaliland during 1940. In 1942, the SDF also played a part in the invasion of the Italian colony by British and Commonwealth forces. The last British governor-general was Robert George Howe.
From 1924 until independence in 1956, the British had a policy of running Sudan as two essentially separate territories, the north and south. The assassination of a Governor-General of Anglo-Egyptian Sudan in Cairo was the causative factor; it brought demands of the newly elected Wafd government from colonial forces. A permanent establishment of two battalions in Khartoum was renamed the Sudan Defence Force acting as under the government, replacing the former garrison of Egyptian army soldiers, saw action afterwards during the Walwal Incident. The Wafdist parliamentary majority had rejected Sarwat Pasha’s accommodation plan with Austen Chamberlain in London; yet Cairo still needed the money. The Sudanese Government's revenue had reached a peak in 1928 at £6.6 million, thereafter the Wafdist disruptions, and Italian borders incursions from Somaliland, London decided to reduce expenditure during the Great Depression. Cotton and gum exports were dwarfed by the necessity to import almost everything from Britain leading to a balance of payments deficit at Khartoum.
In July 1936 the Liberal Constitutional leader, Muhammed Mahmoud was persuaded to bring Wafd delegates to London to sign the Anglo-Egyptian Treaty, "the beginning of a new stage in Anglo-Egyptian relations", wrote Anthony Eden. The British Army was allowed to return to the Sudan to protect the Canal Zone. They were able to find training facilities; and the RAF was free to fly over Egyptian territory. It did not, however, resolve the problem of Sudan: the Sudanese Intelligentsia agitated for a return to metropolitan rule, conspiring with Germany's agents.
The Egyptian revolution of 1952 finally heralded the beginning of the march towards Sudanese independence. Having abolished the monarchy in 1953, Egypt's new leaders, Mohammed Naguib, whose mother was Sudanese, and later Gamal Abdel Nasser, believed the only way to end British domination in Sudan was for Egypt to officially abandon its claims of sovereignty. In addition Nasser knew it would be difficult for Egypt to govern an impoverished Sudan after its independence. The British on the other hand continued their political and financial support for the Mahdist successor, Abd al-Rahman al-Mahdi, whom it was believed would resist Egyptian pressure for Sudanese independence. Rahman was capable of this, but his regime was plagued by political ineptitude, which garnered a colossal loss of support in northern and central Sudan. Both Egypt and Britain sensed a great instability fomenting, and thus opted to allow both Sudanese regions, north and south to have a free vote on whether they wished independence or a British withdrawal.
Sudanese football has a long history. Sudan was one of the four African nations – the others being Egypt, Ethiopia and South Africa – which formed African football. Sudan hosted the first African Cup of Nations in 1956, and has won the African Cup Of Nations once, in 1970. Two years later, the Sudan's National Football Team participated in the 1972 Olympic Games in Munich. The nation's capital is home to the Khartoum League, which is considered to be the oldest football league in Africa.
A polling process was carried out resulting in composition of a democratic parliament and Ismail al-Azhari was elected first Prime Minister and led the first modern Sudanese government. On 1 January 1956, in a special ceremony held at the People's Palace, the Egyptian and British flags were lowered and the new Sudanese flag, composed of green, blue and yellow stripes, was raised in their place by the prime minister Ismail al-Azhari.
Dissatisfaction culminated in a second coup d'état on 25 May 1969. The coup leader, Col. Gaafar Nimeiry, became prime minister, and the new regime abolished parliament and outlawed all political parties. Disputes between Marxist and non-Marxist elements within the ruling military coalition resulted in a briefly successful coup in July 1971, led by the Sudanese Communist Party. Several days later, anti-communist military elements restored Nimeiry to power. In 1972, the Addis Ababa Agreement led to a cessation of the north-south civil war and a degree of self-rule. This led to ten years hiatus in the civil war but an end to American investment in the Jonglei Canal project. This had been considered absolutely essential to irrigate the Upper Nile region and to prevent an environmental catastrophe and wide-scale famine among the local tribes, most especially the Dinka. In the civil war that followed their homeland was raided looted, pillaged and burned. Many of the tribe were murdered in a bloody civil war that raged for over 20 years.
Until the early 1970s, Sudan's agricultural output was mostly dedicated to internal consumption. In 1972, the Sudanese government became more pro-Western, and made plans to export food and cash crops. However, commodity prices declined throughout the 1970s causing economic problems for Sudan. At the same time, debt servicing costs, from the money spent mechanizing agriculture, rose. In 1978, the IMF negotiated a Structural Adjustment Program with the government. This further promoted the mechanised export agriculture sector. This caused great hardship for the pastoralists of Sudan (see Nuba peoples). In 1976, the Ansars had mounted a bloody but unsuccessful coup attempt. But in July 1977, President Nimeiry met with Ansar leader Sadiq al-Mahdi, opening the way for a possible reconciliation. Hundreds of political prisoners were released, and in August a general amnesty was announced for all oppositionists.
Sudan has a rich and unique musical culture that has been through chronic instability and repression during the modern history of Sudan. Beginning with the imposition of strict Salafi interpretation of sharia law in 1989, many of the country's most prominent poets, like Mahjoub Sharif, were imprisoned while others, like Mohammed el Amin (returned to Sudan in the mid-1990s) and Mohammed Wardi (returned to Sudan 2003), fled to Cairo. Traditional music suffered too, with traditional Zār ceremonies being interrupted and drums confiscated . At the same time European militaries contributed to the development of Sudanese music by introducing new instruments and styles; military bands, especially the Scottish bagpipes, were renowned, and set traditional music to military march music. The march March Shulkawi No 1, is an example, set to the sounds of the Shilluk. Northern Sudan listens to different music than the rest of Sudan. A type of music called Aldlayib uses a musical instrument called the Tambur. The Tambur has five strings and is made from wood and makes music accompanied by the voices of human applause and singing artists. This music has a perfect blend that gives the area of the Northern State a special character.
On 30 June 1989, Colonel Omar al-Bashir led a bloodless military coup. The new military government suspended political parties and introduced an Islamic legal code on the national level. Later al-Bashir carried out purges and executions in the upper ranks of the army, the banning of associations, political parties, and independent newspapers, and the imprisonment of leading political figures and journalists. On 16 October 1993, al-Bashir appointed himself "President" and disbanded the Revolutionary Command Council. The executive and legislative powers of the council were taken by al-Bashir.
Education in Sudan is free and compulsory for children aged 6 to 13 years, although more than 40% of children are not going to schools due to the economic situation. Environmental and social factors also increase the difficulty of getting to school, especially for girls. Primary education consists of eight years, followed by three years of secondary education. The former educational ladder 6 + 3 + 3 was changed in 1990. The primary language at all levels is Arabic. Schools are concentrated in urban areas; many in the west have been damaged or destroyed by years of civil war. In 2001 the World Bank estimated that primary enrollment was 46 percent of eligible pupils and 21 percent of secondary students. Enrollment varies widely, falling below 20 percent in some provinces. The literacy rate is 70.2% of total population, male: 79.6%, female: 60.8%.
Stoning remains a judicial punishment in Sudan. Between 2009 and 2012, several women were sentenced to death by stoning. Flogging is a legal punishment. Between 2009 and 2014, many people were sentenced to 40–100 lashes. In August 2014, several Sudanese men died in custody after being flogged. 53 Christians were flogged in 2001. Sudan's public order law allows police officers to publicly whip women who are accused of public indecency.
Crucifixion is a legal punishment. In 2002, 88 people were sentenced to death for crimes relating to murder, armed robbery, and participating in ethnic clashes, Amnesty International wrote that they could be executed by either hanging or crucifixion.
In February 2003, the Sudan Liberation Movement/Army (SLM/A) and Justice and Equality Movement (JEM) groups in Darfur took up arms, accusing the Sudanese government of oppressing non-Arab Sudanese in favor of Sudanese Arabs, precipitating the War in Darfur. The conflict has since been described as a genocide, and the International Criminal Court (ICC) in The Hague has issued two arrest warrants for al-Bashir. Arabic-speaking nomadic militias known as the Janjaweed stand accused of many atrocities.
Since the Darfur crisis in 2004, safe-keeping the central government from the armed resistance and rebellion of paramilitary rebel groups such as the Sudan People's Liberation Army (SPLA), the Sudanese Liberation Army (SLA) and the Justice and Equality Movement (JEM) have been important priorities. While not official, the Sudanese military also uses nomad militias, the most prominent being the Janjaweed, in executing a counter-insurgency war. Somewhere between 200,000 and 400,000 people have died in the violent struggles.
The Sudan People's Liberation Army (SPLA) was the primary member of the Eastern Front, a coalition of rebel groups operating in eastern Sudan. After the peace agreement, their place was taken in February 2004 after the merger of the larger Hausa and Beja Congress with the smaller Rashaida Free Lions. A peace agreement between the Sudanese government and the Eastern Front was signed on 14 October 2006, in Asmara. On 5 May 2006, the Darfur Peace Agreement was signed, aiming at ending the three-year-long conflict. The Chad–Sudan Conflict (2005–2007) had erupted after the Battle of Adré triggered a declaration of war by Chad. The leaders of Sudan and Chad signed an agreement in Saudi Arabia on 3 May 2007 to stop fighting from the Darfur conflict spilling along their countries' 1,000-kilometre (600 mi) border.
On 9 January 2005, the government signed the Nairobi Comprehensive Peace Agreement with the Sudan People's Liberation Movement (SPLM) with the objective of ending the Second Sudanese Civil War. The United Nations Mission in Sudan (UNMIS) was established under the UN Security Council Resolution 1590 to support its implementation. The peace agreement was a prerequisite to the 2011 referendum: the result was a unanimous vote in favour of secession of South Sudan; the region of Abyei will hold its own referendum at a future date.
In December 2005, Sudan became one of the few states to recognise Moroccan sovereignty over Western Sahara.
A letter dated 14 August 2006, from the executive director of Human Rights Watch found that the Sudanese government is both incapable of protecting its own citizens in Darfur and unwilling to do so, and that its militias are guilty of crimes against humanity. The letter added that these human-rights abuses have existed since 2004. Some reports attribute part of the violations to the rebels as well as the government and the Janjaweed. The U.S. State Department's human-rights report issued in March 2007 claims that "[a]ll parties to the conflagration committed serious abuses, including widespread killing of civilians, rape as a tool of war, systematic torture, robbery and recruitment of child soldiers."
Despite being a refugee-generating country, Sudan also hosts a refugee population. According to the World Refugee Survey 2008, published by the U.S. Committee for Refugees and Immigrants, 310,500 refugees and asylum seekers lived in Sudan in 2007. The majority of this population came from Eritrea (240,400 people), Chad (45,000), Ethiopia (49,300) and the Central African Republic (2,500). The Sudanese government UN High Commissioner for Refugees in 2007 forcibly deported at least 1,500 refugees and asylum seekers during the year. Sudan is a party to the 1951 Convention Relating to the Status of Refugees.
Even with the oil profits before the secession of South Sudan, Sudan still faced formidable economic problems, and its growth was still a rise from a very low level of per capita output. The economy of Sudan has been steadily growing over the 2000s, and according to a World Bank report the overall growth in GDP in 2010 was 5.2 percent compared to 2009 growth of 4.2 percent. This growth was sustained even during the war in Darfur and period of southern autonomy preceding South Sudan's independence. Oil was Sudan's main export, with production increasing dramatically during the late 2000s, in the years before South Sudan gained independence in July 2011. With rising oil revenues, the Sudanese economy was booming, with a growth rate of about nine percent in 2007. The independence of oil-rich South Sudan, however, placed most major oilfields out of the Sudanese government's direct control and oil production in Sudan fell from around 450,000 barrels per day (72,000 m /d) to under 60,000 barrels per day (9,500 m /d). Production has since recovered to hover around 250,000 barrels per day (40,000 m /d) for 2014–15.
In July 2007 the country was hit by devastating floods, with over 400,000 people being directly affected. Since 2009, a series of ongoing conflicts between rival nomadic tribes in Sudan and South Sudan have caused a large number of civilian casualties.
Over 2.8 million civilians have been displaced and the death toll is estimated at 300,000 killed. Both government forces and militias allied with the government are known to attack not only civilians in Darfur, but also humanitarian workers. Sympathisers of rebel groups are arbitrarily detained, as are foreign journalists, human-rights defenders, student activists and displaced people in and around Khartoum, some of whom face torture. The rebel groups have also been accused in a report issued by the U.S. government of attacking humanitarian workers and of killing innocent civilians. According to UNICEF, in 2008, there were as many as 6,000 child soldiers in Darfur.
The main purpose of the dam will be the generation of electricity. Its dimensions make it the largest contemporary hydropower project in Africa. The construction of the dam was finished December 2008, supplying more than 90 percent of the population with electricity. Other gas-powered generating stations are operational in Khartoum State and other states.
In 2010, Sudan was considered the 17th-fastest-growing economy in the world and the rapid development of the country largely from oil profits even when facing international sanctions was noted by The New York Times in a 2006 article. Because of the secession of South Sudan, which contained over 80 percent of Sudan's oilfields, Sudan entered a phase of stagflation, GDP growth slowed to 3.4 percent in 2014, 3.1 percent in 2015 and is projected to recover slowly to 3.7 percent in 2016 while inflation remained as high as 21.8% as of 2015 .
The Sudanese conflict in South Kordofan and Blue Nile in the early 2010s between the Army of Sudan and the Sudan Revolutionary Front started as a dispute over the oil-rich region of Abyei in the months leading up to South Sudanese independence in 2011, though it is also related to civil war in Darfur that is nominally resolved. The events would later be known as the Sudanese Intifada, which would end only in 2013 after al-Bashir promised he would not seek re-election in 2015. He later broke his promise and sought re-election in 2015, winning through a boycott from the opposition who believed that the elections would not be free and fair. Voter turnout was at a low 46%.
In order to export oil, South Sudan relies on a pipeline to Port Sudan on Sudan's Red Sea coast, as South Sudan is a landlocked country, as well as the oil refining facilities in Sudan. In August 2012, Sudan and South Sudan agreed a deal to transport South Sudanese oil through Sudanese pipelines to Port Sudan.
In 2015, Sudan participated in the Saudi Arabian-led intervention in Yemen against the Shia Houthis and forces loyal to former President Ali Abdullah Saleh, who was deposed in the 2011 uprising.
Sudan has around 25–30 universities; instruction is primarily in Arabic. Education at the secondary and university levels has been seriously hampered by the requirement that most males perform military service before completing their education. In addition, the "Islamisation" encouraged by president Al-Bashir alienated many researchers: the official language of instruction in universities was changed from English to Arabic and Islamic courses became mandatory. Internal science funding withered. According to UNESCO, more than 3,000 Sudanese researchers left the country between 2002 and 2014. By 2013, the country had a mere 19 researchers for every 100,000 citizens, or 1/30 the ratio of Egypt, according to the Sudanese National Centre for Research. In 2015, Sudan published only about 500 scientific papers. For comparison, Poland, a country of similar population size, publishes on the order of 10,000 papers per year.
Sudan has a life expectancy of 64.5 years (62.9 for males and 66.1 for females) according to the latest data for the year 2016 from the World Bank. Infant mortality in 2016 was 44.8 per 1,000.
On 13 January 2017 US president Barack Obama, signed an Executive Order that lifted many sanctions placed against Sudan and assets of its government held abroad. On 6 October 2017, the following US president Donald Trump lifted most of the remaining sanctions against the country and its petroleum, export-import, and property industries.
A report published by Human Rights Watch in 2018 revealed that Sudan has made no meaningful attempts to provide accountability for past and current violations. The report documented human rights abuses against civilians in Darfur, southern Kordofan, and Blue Nile. During 2018, the National Intelligence and Security Service (NISS) used excessive force to disperse protests and detained dozens of activists and opposition members. Moreover, the Sudanese forces blocked United Nations-African Union Hybrid Operation and other international relief and aid agencies to access to displaced people and conflict-ridden areas in Darfur.
On 19 December 2018, massive protests began after a government decision to triple the price of goods at a time when the country was suffering an acute shortage of foreign currency and inflation of 70 percent. In addition, President al-Bashir, who had been in power for more than 30 years, refused to step down, resulting in the convergence of opposition groups to form a united coalition. The government retaliated by arresting more than 800 opposition figures and protesters, leading to the death of approximately 40 people according to the Human Rights Watch, although the number was much higher than that according to local and civilian reports. The protests have continued since the overthrow of his government on 11 April 2019, when President al-Bashir was arrested and a three-month state of emergency was enacted. Over 100 people died in early June in clashes between pro-democracy protesters and state security forces, resulting in Sudan's suspension from the African Union. Sudan's youth has been reported to be driving the protests.
In June 2019, Sudan was suspended from the African Union over orders to violently confront pro-democracy protesters, which left over 100 civilians dead.
In July 2019, UN ambassadors of 37 countries, including Sudan, have signed a joint letter to the UNHRC defending China's treatment of Uyghurs in the Xinjiang region.
