Ivan V Alekseyevich (6 September [O.S. 27 August] 1666 8 February [O.S. 29 January] 1696) 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.
