What is the name of the Eurasian empire that was founded in 1721 when Peter I was declared emperor?

The Russian Empire was created when Peter the Great (Peter I) was named emperor. At its height, the Russian Empire covered most of the same territory as the U.S.S.R. The Russian Empire came to an end in 1917 with the abdication, and later assassination of Nicholas II by the Bolsheviks during the Russian Revolution.
