A schism is a division or separation between people, typically within an organization, movement, or religious group. It often refers to a split within a religious body, like the Great East-West Schism, but can also describe divisions in non-religious contexts, such as between individuals in a friendship or romantic relationship.
Following the fall of the Ottoman Empire in 1923, there hasn't been a widely recognized Caliph within Sunni Islam. This event marked a significant turning point in the history of the Caliphate, which had transitioned from a democratically elected position to a hereditary dynastic rule after the first four Rightly Guided Caliphs.

In 2004, a schism, a break of communion, occurred between Patriarch Bartholomew I of Constantinople and Archbishop Christodoulos of Athens.

In 2018, a significant schism occurred within Eastern Orthodoxy. This division arose between the Ecumenical Patriarchate of Constantinople, the primatial See of Eastern Orthodoxy, and the Russian Orthodox Church. The controversy stemmed from Constantinople's decision to grant autocephaly, or independence, to the Orthodox Church of Ukraine.
