Ivan IV Vasilyevich (25 August 1530 – 28 March 1584), more often known in English as Ivan the Terrible, was the first Tsar (Emperor) of Russia, and before that was the Grand Prince of Moscow. He was called Ivan the Terrible because in those days the word terrible meant "formidable" or "fearsome", not "really bad". This is comes from his Russian nickname "Ivan Grozny", which also means "Ivan the Formidable".
