The last Tsar of Russia was Nicholas Romanov II. There are some who claim that Nicholas II was not the last Tsar but that either his brother Michael was or his son Alexei was. These are non-sense. Nicholas II abdicated the throne in March 1917 in favor of his brother Michael, however according to Russian law, the title of Tsar was not Nicholas's to give to any person he desired. It had to go to the Tsar's eldest male child, Alexei. In any event, Michael refused to accept the title and was never crowned Tsar, so he was not the last Tsar. The title was by law supposed to go to Alexei, but the abdication itself was questionable. Alexei was likewise never crowned or acted as Tsar. The last Tsar was without a doubt Nicholas II.
