Russia stopped being a monarchy in 1917, when the Russian Revolution overthrew the Romanov dynasty. This led to the establishment of a communist government and the formation of the Russian Soviet Federative Socialist Republic. However, it wasn't until 1991, with the dissolution of the Soviet Union, that Russia officially became a federal semi-presidential republic.
