Peter I the Great or Pyotr Alexeyevich Romanov (Russian: Пётр Алексе́евич Рома́нов, Пётр I, Pyotr I, or Пётр Вели́кий, Pyotr Velikiy) (9 June [O.S. 30 May] 1672 – 8 February [O.S. 28 January] 1725) ruled Russia and later the Russian Empire from 7 May [O.S. 27 April] 1682 until his death, jointly ruling before 1696 with his weak and sickly half-brother, Ivan V.
Peter the Great carried out a policy of modernization and expansion that transformed the Tsardom of Russia into the 3-billion acre Russian Empire, a major European power.
