Ivan V of Russia

Ivan V Alekseyevich (Russian: Иван V Алексеевич, – ) was a joint Tsar of Russia (with his younger half-brother Peter I) who co-reigned between 1682 and 1696. He was the youngest son of Alexis I of Russia and Maria Miloslavskaya. His reign was only formal, since he had serious physical and mental disabilities. He sat still for hours at a time and needed assistance in order to walk.
