Peter the Great, Peter I 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 the Tsardom of Russia and later the Russian Empire from 7 May [O.S. 27 April] 1682 until his death, jointly ruling before 1696 with his half-brother. In numerous successful wars he expanded the Tsardom into a huge empire that became a major European power. According to historian James Cracraft, he led a cultural revolution that replaced the traditionalist and medieval social and political system with a modern, scientific, Europe-oriented, and rationalist system. Peter the Great had two wives, with whom he had fourteen children; three of them survived to adulthood. His eldest child and heir, Alexei, was suspected of being involved in a plot to overthrow the Emperor. Alexei was tried and confessed under torture during questioning conducted by a secular court. He was convicted and sentenced to be executed. The sentence could be carried out only with Peter's signed authorization, and Alexei died in prison, as Peter hesitated before making the decision. Alexei's death most likely resulted from injuries suffered during his torture.
