Demand for new construction has contributed to frequent demolition of older buildings, freeing space for modern high-rises. However, many examples of European and Lingnan architecture are still found throughout the territory. Older government buildings are examples of colonial architecture. The 1846 Flagstaff House, the former residence of the commanding British military officer, is the oldest Western-style building in Hong Kong. Some (including the Court of Final Appeal Building and the Hong Kong Observatory) retain their original function, and others have been adapted and reused; the Former Marine Police Headquarters was redeveloped into a commercial and retail complex, and Béthanie (built in 1875 as a sanatorium) houses the Hong Kong Academy for Performing Arts. The Tin Hau Temple, dedicated to the sea goddess Mazu (originally built in 1012 and rebuilt in 1266), is the territory's oldest existing structure. The Ping Shan Heritage Trail has architectural examples of several imperial Chinese dynasties, including the Tsui Sing Lau Pagoda (Hong Kong's only remaining pagoda).
The earliest European visitor was Portuguese explorer Jorge Álvares, who arrived in 1513. Portuguese merchants established a trading post called Tamão in Hong Kong waters and began regular trade with southern China. Although the traders were expelled after military clashes in the 1520s, Portuguese-Chinese trade relations were re-established by 1549. Portugal acquired a permanent lease for Macau in 1557.
After the Qing conquest, maritime trade was banned under the Haijin policies. From 1661 to 1683, the population of most of the area forming present day Hong Kong was cleared under the Great Clearance, turning the region into a wasteland. The Kangxi Emperor lifted the maritime trade prohibition, allowing foreigners to enter Chinese ports in 1684. Qing authorities established the Canton System in 1757 to regulate trade more strictly, restricting non-Russian ships to the port of Canton. Although European demand for Chinese commodities like tea, silk, and porcelain was high, Chinese interest in European manufactured goods was insignificant, so that Chinese goods could only be bought with precious metals. To reduce the trade imbalance, the British sold large amounts of Indian opium to China. Faced with a drug crisis, Qing officials pursued ever more aggressive actions to halt the opium trade.
The name of the territory, first romanised as "He-Ong-Kong" in 1780, originally referred to a small inlet located between Aberdeen Island and the southern coast of Hong Kong Island. Aberdeen was an initial point of contact between British sailors and local fishermen. Although the source of the romanised name is unknown, it is generally believed to be an early phonetic rendering of the Cantonese (or Tanka Cantonese) phrase hēung góng. The name translates as "fragrant harbour" or "incense harbour". "Fragrant" may refer to the sweet taste of the harbour's freshwater influx from the Pearl River or to the odour from incense factories lining the coast of northern Kowloon. The incense was stored near Aberdeen Harbour for export before Victoria Harbour was developed. Sir John Davis (the second colonial governor) offered an alternative origin; Davis said that the name derived from "Hoong-keang" ("red torrent"), reflecting the colour of soil over which a waterfall on the island flowed.
In 1839, the Daoguang Emperor rejected proposals to legalise and tax opium and ordered imperial commissioner Lin Zexu to eradicate the opium trade. The commissioner destroyed opium stockpiles and halted all foreign trade, triggering a British military response and the First Opium War. The Qing surrendered early in the war and ceded Hong Kong Island in the Convention of Chuenpi. British forces began controlling Hong Kong shortly after the signing of the convention, from 26 January 1841. However, both countries were dissatisfied and did not ratify the agreement. After more than a year of further hostilities, Hong Kong Island was formally ceded to the United Kingdom in the 1842 Treaty of Nanking.
Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War. The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained a 99-year lease of the New Territories in 1898. Hong Kong was occupied by Japan from 1941 to 1945 during World War II. The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems.
Hong Kong has a humid subtropical climate (Köppen Cwa), characteristic of southern China, despite being located south of the Tropic of Cancer, although closely bordering on a tropical climate. Summers are long, hot and humid, with occasional showers and thunderstorms and warm air from the southwest. The humid nature of Hong Kong exacerbates the warmth of summer. Typhoons occur most often then, sometimes resulting in floods or landslides. Winters are short, mild and usually sunny at the beginning, becoming cloudy towards February. Frequent cold fronts bring strong, cooling winds from the north and occasionally result in chilly weather. Autumn is the sunniest season, whilst spring is generally cloudy. Snowfall has been extremely rare in Hong Kong; the last reported instance was on Tai Mo Shan in 1975. Hong Kong averages 1,709 hours of sunshine per year. Historic temperature extremes at the Hong Kong Observatory are 36.6 °C (97.9 °F) on 22 August 2017 and 0.0 °C (32.0 °F) on 18 January 1893. The highest and lowest recorded temperatures in all of Hong Kong are 39.0 °C (102 °F) at Wetland Park on 22 August 2017, and −6.0 °C (21.2 °F) at Tai Mo Shan on 24 January 2016.
The colony was further expanded in 1898 when the United Kingdom obtained a 99-year lease of the New Territories. The University of Hong Kong was established in 1911 as the territory's first institution of higher education. Kai Tak Airport began operation in 1924, and the colony avoided a prolonged economic downturn after the 1925–26 Canton–Hong Kong strike. At the start of the Second Sino-Japanese War in 1937, Governor Geoffry Northcote declared Hong Kong a neutral zone to safeguard its status as a free port. The colonial government prepared for a possible attack, evacuating all British women and children in 1940. The Imperial Japanese Army attacked Hong Kong on 8 December 1941, the same morning as its attack on Pearl Harbor. Hong Kong was occupied by Japan for almost four years before the British resumed control on 30 August 1945.
Hong Kong has eleven universities. The University of Hong Kong (HKU) was founded as the city's first institute of higher education during the early colonial period in 1911. The Chinese University of Hong Kong (CUHK) was established in 1963 to fill the need for a university that taught using Chinese as its primary language of instruction. Along with the Hong Kong University of Science and Technology (HKUST) established in 1991, these universities are consistently ranked among the top 50 or top 100 universities worldwide.
Its population rebounded quickly after the war, as skilled Chinese migrants fled from the Chinese Civil War and more refugees crossed the border when the Chinese Communist Party took control of mainland China in 1949. Hong Kong became the first of the Four Asian Tiger economies to industrialise during the 1950s. With a rapidly increasing population, the colonial government attempted reforms to improve infrastructure and public services. The public-housing estate programme, Independent Commission Against Corruption, and Mass Transit Railway were all established during the post-war decades to provide safer housing, integrity in the civil service, and more reliable transportation.
Hong Kong developed into a filmmaking hub during the late 1940s as a wave of Shanghai filmmakers migrated to the territory, and these movie veterans helped build the colony's entertainment industry over the next decade. By the 1960s, the city was well known to overseas audiences through films such as The World of Suzie Wong. When Bruce Lee's The Way of the Dragon was released in 1972, local productions became popular outside Hong Kong. During the 1980s, films such as A Better Tomorrow, As Tears Go By, and Zu Warriors from the Magic Mountain expanded global interest beyond martial arts films; locally made gangster films, romantic dramas, and supernatural fantasies became popular.
Dragon boat races originated as a religious ceremony conducted during the annual Tuen Ng Festival. The race was revived as a modern sport as part of the Tourism Board's efforts to promote Hong Kong's image abroad. The first modern competition was organised in 1976, and overseas teams began competing in the first international race in 1993.
Although the territory had one of Asia's largest manufacturing economies during the latter half of the colonial era, Hong Kong's economy is now dominated by the service sector. The sector generates 92.7% of economic output, with the public sector accounting for about 10%. Between 1961 and 1997 Hong Kong's gross domestic product increased by a factor of 180, and per capita GDP increased by a factor of 87. The territory's GDP relative to mainland China's peaked at 27% in 1993; it fell to less than 3% in 2017, as the mainland developed and liberalised its economy. Economic and infrastructure integration with China has increased significantly since the 1978 start of market liberalisation on the mainland. Since resumption of cross-boundary train service in 1979, many rail and road links have been improved and constructed, facilitating trade between regions. The Closer Economic Partnership Arrangement formalised a policy of free trade between the two areas, with each jurisdiction pledging to remove remaining obstacles to trade and cross-boundary investment. A similar economic partnership with Macau details the liberalisation of trade between the special administrative regions. Chinese companies have expanded their economic presence in the territory since the handover. Mainland firms represent over half of the Hang Seng Index value, up from 5% in 1997.
The colony faced an uncertain future as the end of the New Territories lease approached, and Governor Murray MacLehose raised the question of Hong Kong's status with Deng Xiaoping in 1979. Diplomatic negotiations with China resulted in the 1984 Sino-British Joint Declaration, in which the United Kingdom agreed the handover of the colony in 1997 and China would guarantee Hong Kong's economic and political systems for 50 years after the handover. The impending handover triggered a wave of mass emigration as residents feared an erosion of civil rights, the rule of law, and quality of life. Over half a million people left the territory during the peak migration period, from 1987 to 1996. The Legislative Council became a fully elected legislature for the first time in 1995 and extensively expanded its functions and organisations throughout the last years of the colonial rule. The handover of Hong Kong to China was at midnight on 1 July 1997, after 156 years of British rule.
Hong Kong represents itself separately from mainland China, with its own sports teams in international competitions. The territory has participated in almost every Summer Olympics since 1952 and has earned nine medals. Lee Lai-shan won the territory's first Olympic gold medal at the 1996 Atlanta Olympics, and Cheung Ka Long won the second one in Tokyo 2020. Hong Kong athletes have won 126 medals at the Paralympic Games and 17 at the Commonwealth Games. No longer part of the Commonwealth of Nations, the city's last appearance in the latter was in 1994.
The Hong Kong Polytechnic University (PolyU) and City University of Hong Kong (CityU), both granted university status in 1994, are consistently ranked among the top 100 or top 200 universities worldwide. The Hong Kong Baptist University (HKBU) was granted university status in 1994 and is a liberal arts institution. Lingnan University, Education University of Hong Kong, Hong Kong Metropolitan University (formerly Open University of Hong Kong), Hong Kong Shue Yan University and Hang Seng University of Hong Kong all attained full university status in subsequent years.
As the mainland liberalised its economy, Hong Kong's shipping industry faced intense competition from other Chinese ports. Half of China's trade goods were routed through Hong Kong in 1997, dropping to about 13% by 2015. The territory's minimal taxation, common law system, and civil service attract overseas corporations wishing to establish a presence in Asia. The city has the second-highest number of corporate headquarters in the Asia-Pacific region. Hong Kong is a gateway for foreign direct investment in China, giving investors open access to mainland Chinese markets through direct links with the Shanghai and Shenzhen stock exchanges. The territory was the first market outside mainland China for renminbi-denominated bonds, and is one of the largest hubs for offshore renminbi trading. In November 2020, Hong Kong's Financial Services and the Treasury Bureau proposed a new law that will restrict cryptocurrency trading to professional investors only, leaving amateur traders (93% of Hong Kong's trading population) out of the market. The Hong Kong dollar, the local currency, is the eighth most traded currency in the world. Due to extremely compact house sizes and the extremely high housing density, the city has the most expensive housing market in the world.
Earliest known human traces in what is now Hong Kong are dated by some to 35,000 and 39,000 years ago during the Paleolithic period. The claim is based on an archaeological investigation in Wong Tei Tung, Sai Kung in 2003. The archaeological works revealed knapped stone tools from deposits that were dated using optical luminescence dating.
Political debates after the handover have centred around the region's democratic development and the Chinese central government's adherence to the "one country, two systems" principle. After reversal of the last colonial era Legislative Council democratic reforms following the handover, the regional government unsuccessfully attempted to enact national security legislation pursuant to Article 23 of the Basic Law. The central government decision to implement nominee pre-screening before allowing chief executive elections triggered a series of protests in 2014 which became known as the Umbrella Revolution. Discrepancies in the electoral registry and disqualification of elected legislators after the 2016 Legislative Council elections and enforcement of national law in the West Kowloon high-speed railway station raised further concerns about the region's autonomy. In June 2019, mass protests erupted in response to a proposed extradition amendment bill permitting the extradition of fugitives to mainland China. The protests are the largest in Hong Kong's history, with organisers claiming to have attracted more than three million Hong Kong residents.
Tourism is a major part of the economy, accounting for 5% of GDP. In 2016, 26.6 million visitors contributed HK$258 billion (US$32.9 billion) to the territory, making Hong Kong the 14th most popular destination for international tourists. It is the most popular Chinese city for tourists, receiving over 70% more visitors than its closest competitor (Macau). The city is ranked as one of the most expensive cities for expatriates. However, since 2020, there has been a sharp decline in incoming visitors due to tight COVID-19 travel restrictions. Additionally, due to the closure of Russian airspace in 2022, multiple airlines decided to cease their operations in Hong Kong. In an attempt to attract tourists back to Hong Kong, the Hong Kong government announced plans to give away 500,000 free airline tickets in 2023.
Hong Kong cinema continued to be internationally successful over the following decade with critically acclaimed dramas such as Farewell My Concubine, To Live, and Chungking Express. The city's martial arts film roots are evident in the roles of the most prolific Hong Kong actors. Jackie Chan, Donnie Yen, Jet Li, Chow Yun-fat, and Michelle Yeoh frequently play action-oriented roles in foreign films. Hong Kong films have also grown popular in oversea markets such as Japan, South Korea, and Southeast Asia, earning the city the moniker "Hollywood of the East". At the height of the local movie industry in the early 1990s, over 400 films were produced each year; since then, industry momentum shifted to mainland China. The number of films produced annually has declined to about 60 in 2017.
The Joint Declaration guarantees the Basic Law of Hong Kong for 50 years after the handover. It does not specify how Hong Kong will be governed after 2047, and the central government's role in determining the territory's future system of government is the subject of political debate and speculation. Hong Kong's political and judicial systems may be integrated with China's at that time, or the territory may continue to be administered separately. However, in response to large-scale protests in 2019 and 2020, the Standing Committee of the National People's Congress passed the controversial Hong Kong national security law. The law criminalises secession, subversion, terrorism and collusion with foreign elements and establishes the Office for Safeguarding National Security of the CPG in the HKSAR, an investigative office under Central People's Government authority immune from HKSAR jurisdiction. Some of the aforementioned acts were previously considered protected speech under Hong Kong law. The United Kingdom considers the law to be a serious violation of the Joint Declaration. In October 2020, Hong Kong police arrested seven pro-democracy politicians over tussles with pro-Beijing politicians in the Legislative Council in May. They were charged with contempt and interfering with members of the council, while none of the pro-Beijing lawmakers were detained. Annual commemorations of the 1989 Tiananmen Square protests and massacre were also cancelled amidst fears of violating the national security law. In March 2021, the Chinese central government unilaterally changed Hong Kong's electoral system and established the Candidate Eligibility Review Committee, which would be tasked with screening and evaluating political candidates for their "patriotism".
The Hong Kong regional government and Chinese central government responded to the protests with a number of administrative measures to quell dissent. In June 2020, the Legislative Council passed the National Anthem Ordinance, which criminalised "insults to the national anthem of China". The Chinese central government meanwhile enacted the Hong Kong national security law to help quell protests in the region. Nine months later, in March 2021, the Chinese central government introduced amendments to Hong Kong's electoral system, which included the reduction of directly elected seats in the Legislative Council and the requirement that all candidates be vetted and approved by a Beijing-appointed Candidate Eligibility Review Committee.
The imposition of the Hong Kong national security law by the central government in Beijing in June 2020 resulted in the suspension of bilateral extradition treaties by the United Kingdom, Canada, Australia, New Zealand, Finland, and Ireland. The United States ended its preferential economic and trade treatment of Hong Kong in July 2020 because it was no longer able to distinguish Hong Kong as a separate entity from the People's Republic of China. In 2024, the Safeguarding National Security Ordinance was passed by the Legislative Council to grant officials "even more powers to crack down on opposition to Beijing and the Hong Kong government" and includes penalties such as life imprisonment for political crimes such as treason and insurrection. Critics state that this expansion "will strike a lasting blow to the partial autonomy the city had been promised by China."
One of the world's most significant financial centres and commercial ports, Hong Kong has a market economy focused on services, characterised by low taxation, minimal government market intervention, and an established international financial market. It is the world's 35th-largest economy, with a nominal GDP of approximately US$373 billion. Hong Kong's economy ranked at the top of the Heritage Foundation's economic freedom index between 1995 and 2021. However, Hong Kong was removed from the index by the Heritage Foundation in 2021, with the Foundation citing a "loss of political freedom and autonomy ... [making Hong Kong] almost indistinguishable in many respects from other major Chinese commercial centers like Shanghai and Beijing". Hong Kong is highly developed, and ranks fourth on the UN Human Development Index. The Hong Kong Stock Exchange is the seventh-largest in the world, with a market capitalisation of HK$30.4 trillion (US$3.87 trillion) as of December 2018 . Hong Kong is ranked as the 17th most innovative territory in the Global Innovation Index in 2023, and 3rd in the Global Financial Centres Index. The city is sometimes referred to as "Silicon Harbor", a nickname derived from Silicon Valley in California. Hong Kong hosts several high tech and innovation companies, including several multinational companies.
The Census and Statistics Department estimated Hong Kong's population at 7,413,070 in 2021. The overwhelming majority (91.6%) is Han Chinese, most of whom are Taishanese, Teochew, Hakka, and other Cantonese peoples. The remaining 8.4% are non-ethnic Chinese minorities, primarily Filipinos, Indonesians, and South Asians. However, most Filipinos and Indonesians in Hong Kong are short-term workers. According to a 2021 thematic report by the Hong Kong government, after excluding foreign domestic helpers, the real number of non-Chinese ethnic minorities in the city was 301,344, or 4% of Hong Kong's population. About half the population have some form of British nationality, a legacy of colonial rule; 3.4 million residents have British National (Overseas) status, and 260,000 British citizens live in the territory. The vast majority also hold Chinese nationality, automatically granted to all ethnic Chinese residents at the handover. Headline population density exceeds 7,060 people/km , and is the fourth-highest in the world.
Life expectancy in Hong Kong was 81.3 years for males and 87.2 years for females in 2022, one of the highest in the world. Cancer, pneumonia, heart disease, cerebrovascular disease, and accidents are the territory's five leading causes of death. The universal public healthcare system is funded by general-tax revenue, and treatment is highly subsidised; on average, 95% of healthcare costs are covered by the government.
In May 2023, the Legislative Council also introduced legislation to reduce the number of directly elected seats in the district councils, and a District Council Eligibility Review Committee was similarly established to vet candidates.
The territory is divided into 18 districts, each represented by a district council. These advise the government on local issues such as public facility provisioning, community programme maintenance, cultural promotion, and environmental policy. As of 2019, there are a total of 479 district council seats, 452 of which are directly elected. Rural committee chairmen, representing outlying villages and towns, fill the 27 non-elected seats. In May 2023, the government proposed reforms to the District Council electoral system which further cut the number of directly elected seats from 452 to 88, and total seats from 479 to 470. A requirement that district council candidates be vetted and approved by the District Council Eligibility Review Committee was also proposed. The Legislative Council approved the reforms in July 2023.
