The Church of Greece came into being in 1833 when the Bavarian regency unilaterally proclaimed, in the name of King Otto, its independence from the Patriarchate of Constantinople. By the same royal decree of July 1833 - the work of Georg von Maurer and two prominent supporters of a Greek national church, Theokletos Pharmakidis and Spyridon Trikoupis - it became autocephalous, acquired its own synod, and recognized King Otto as its head.
