Human: What Was the Largest Contiguous Empire in History?

Assistant: Historians define an empire as an expansionist state.  The answer to the question you’ve asked will depend on how expansive you want to be.  The Largest Contiguous Empire was either the British Empire from 1776 to 1947, or the Soviet Empire from the Bolshevik Revolution in 1917 to the dissolution of the Soviet Union in 1991.  When measured by the percentage of the Earth’s total land surface, the Mongol Empire of Genghis Khan in 1206 was the largest.  However, it was an empire of conquest, so it only gained an increase in area when the conquered territory was incorporated into Mongolian territory.
