After the Soviets took over Armenia in 1920, the Armenian American community was divided into two camps: one supporting Soviet Armenia (mostly members of the Hunchak and Ramgavar parties), another one against it (mostly made up of ARF members). During the 1933 World's Fair, Leon Tourian, the primate of the Eastern Diocese of the Armenian Apostolic Church of America, refused to give a speech because the Armenian tricolor of the 1918-1920 Republic was hanging behind him, while Etchmiadzin, the seat of the Catholicos of All Armenians, was in Armenia that was then part of the Soviet Union and used a different flag. This upset the Dashnak members present in the ceremony. The conflict reached a crisis on 24 December 1933, when several members of ARF assassinated Archbishop Tourian during the Christmas Eve service in New York's Holy Cross Armenian Apostolic Church.
