Catholicos-Patriarch has been the title of the heads of the Georgian Orthodox Church since 1010, shortly after the unification of the Kingdom of Georgia. The first Catholicos-Patriarch of All Georgia was Melkisedek I (1010–1033). In the 15th century, with the collapse of the Kingdom, the Georgian Orthodox Church was divided into the East and the West parts and accordingly they were ruled by the Catholicos-Patriarch of East Georgia and the Catholicos-Patriarch of West Georgia.
In 1801, the Kingdom of Kartli-Kakheti (Eastern Georgia) was occupied and annexed by the Tsarist Russian Empire. In 1811, the autocephalous status (independence) of the Georgian Orthodox Church was abolished by Russia and the Russian Orthodox Church took over its administration.
In 1917, the autocephaly of the Georgian Orthodox Church was restored. The first Catholicos-Patriarch of All Georgia since the restoration of autocephaly was Kyrion II Sadzaglishvili (1917–1918).
To date there have been 82 Catholicos-Patriarchs, of whom 7 have been formally glorified by the Georgian Orthodox Church.
