The Apostolic Autocephalous Orthodox Church of Georgia (Georgian: แกแแฅแแ แแแแแแก แกแแแแชแแฅแฃแแ แแแขแแแแคแแแฃแ แ แแแ แแแแแแแแแแแแ แแแแแกแแ, romanized: sakartvelos samotsikulo avt'ok'epaluri martlmadidebeli ek'lesia), commonly known as the Georgian Orthodox Church or the Orthodox Church of Georgia, is an autocephalous Eastern Orthodox church in full communion with the other churches of Eastern Orthodoxy. It is Georgia's dominant religious institution, and a majority of Georgian people are members. The Orthodox Church of Georgia is one of the oldest churches in the world. It asserts apostolic foundation, and that its historical roots can be traced to the early and late Christianization of Iberia and Colchis by Andrew the Apostle in the 1st century AD and by Saint Nino in the 4th century AD, respectively. As in similar autocephalous Eastern Orthodox Christian churches, the church's highest governing body is the holy synod of bishops. The church is headed by the Patriarch of All Georgia, Ilia II, who was elected in 1977.
Eastern Orthodox Christianity was the state religion throughout most of Georgia's history until 1921, when the country, having declared independence from Russia in 1918, was occupied by the Red Army during the Soviet invasion of Georgia, becoming part of the Soviet Union. The current Constitution of Georgia recognizes the special role of the Georgian Orthodox Church in the country's history, but also stipulates the independence of the church from the state. Government relations are further defined and regulated by the Concordat of 2002.
