100 largest empires in history

Following the previous comments, there are several mistakes made while making this quiz!

Got to 70, and now I've got like 30 different central asian empires/khanates to look up haha

Filling in all of the Chinese dynasties under "China" but not the Soviet Union under "Russia" seems absurd. "India" fills a lot of empires geographically related (but not really politically) but Iran doesn't. Would be nice to have a good set of criteria on this.

Also, is the "Land aria" at the maximum extent? Some of the states you listed were bigger at some point in the past. The US had an area of 10.1 million km at the beginning of the 20th century, for example.

You also need to standardize your type-in generality. Why does "China" yield every Chinese dynasty, while "India" yields some but not all Indian dynasties (Gupta but not Mauryan, for example), and "Iran" yields only the Achaemenids but not Sasanians, Safavids, Ashfarids, etc. Decide upon a rule for when a general regional/cultural name counts as a type-in, and apply that rule consistently. This rule should be listed in the description.

You also need to accept alternate type-ins for many answers, such as Khwarezmia/Khwarazmia, Sassanid/Sasanian, etc.

Additionally, sizes need to be fixed. Write Sq. Km. instead of Km, and specify in the description that "Maximum estimates of land area are listed."

The mode of production, while not perfect, was not capitalist/feudal, the only systems which beget Imperialism. It did not exploit its holdings, and in fact provided equal rights to all Soviet citizens, while providing infrastructure and education, and didn't exploit its workers anywhere close to how they were being exploited under the Tsarist regime, or even to how the Bourgeoisie of the former Soviet Republics exploits them to this day.

-Gran Colombia

Australia's size actually peaked before 1975, when they owned Papua New Guinea. Their size then was around 8.1M km²
