Iuliu Maniu was an Austro-Hungarian-born lawyer and Romanian politician. He was a leader of the National Party of Transylvania and Banat before and after World War I, playing an important role in the Union of Transylvania with Romania.
Maniu served as Prime Minister of Romania for three terms during 1928–1933, and, with Ion Mihalache, co-founded the National Peasants' Party. Arrested by the ascendant communist authorities in 1947 as a result of the Tămădău affair, he was convicted of treason in a show trial and sent to Sighet Prison, where he died six years later.
