Samoil Mirza was an Austro-Hungarian-born Romanian photographer best known for taking the only photographs of the 1918 Great National Assembly at Alba Iulia, where Transylvania united with Romania. Born in Transylvania, Mirza apprenticed as a photographer and served in World War I, becoming one of Romania's first war photographers. In late 1918, he traveled to Alba Iulia to photograph the unification assembly, taking the historic images that documented Romania's national day. His photographs became politically and historically significant as representations of Transylvania joining Romania.
