Czar

A Czar, often spelled Tsar, was a title used to describe the rulers of Russia from the 16th century until the early 20th century. It comes from the Latin word "Caesar," suggesting imperial authority. Czars held absolute power, ruling with centralized authority over the vast Russian Empire. The most famous among them include Ivan the Terrible and Peter the Great, who expanded and modernized Russia. The reign of the Czars ended with the Russian Revolution in 1917, which led to the establishment of a communist government and the execution of the last Czar, Nicholas II, and his family.
