A government controlled by a Tsar (Czar) is called a Tsarist Autocracy. Essentially a form of absolute monarchy.
It was an Empire, ruled by the Czar of Russia, Nicholas II. In 1914 the Czar - although he had his powers partly delegated to his ministers, and although there was a Parliament (the Duma) with limited powers - ruled as an "autocrat," an absolute ruler with basically unlimited power.
Russia was a monarchy run by Czar Nicholas II until he abdicated the throne in March 1917. Then it was ruled by a government of ministers called the Provisional Government until the Communist takeover in October 1917.
