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