Iuliu Maniu was a Romanian politician who served as Prime Minister of Romania for three terms between 1928-1933. He was a leader of the National Party of Transylvania and Banat before and after World War II, and co-founded the National Peasants' Party. In 1918, Maniu led an intensive unionist campaign that resulted in Transylvania separating from Austria-Hungary and joining Romania. He became the head of Transylvania's Directory Council after the union. However, Maniu later opposed some actions by King Ferdinand I and Prime Minister Alexandru Averescu, seeing them as attempts to tie multi-religious Transylvania more closely to Orthodoxy.
