Largest Empire in the World | List of Greatest Empires in History

This is a list of the world's largest empires in history, but this list cannot be fully considered as the "empire" which is very difficult to be kept in this category, and has been a subject of controversy among the scholars. The values given here should generally be interpreted as indicative, and not as the determination of a precise ordering.

For reference, note that the Earth's total land area is 148,940,000 km² (57,510,000 square miles). This list belongs to those empires, whose territories have been more than 2% of the total area.

The list includes large multi-ethnic and mono-ethnic states with monarchical and other forms of government, including countries that actively participated in colonialism (USA) until 1945.
