The greatest European powers included Rome, Holy Roman Empire, France, and the Byzantine Empire.

The largest contiguous empire (the largest empire confined to a single land mass) was the Mongol Empire which, at its largest extent covered 33,000,000 sq km or 12,741,000 sq miles, some 22% of the earth's total land area. The Mongol Empire was the second largest empire after the British Empire which was a maritime empire and not confined to a single land mass. The British Empire was the largest empire in history. At it's peak the Brirish Empire covered 36.6 million km² of land and contained around a quarter of the worlds population. After World War II much of the British Empire territories declared independence. Most still retain a close relationship with Britain, some even choosing to retain the British Monarch.
