who built the world's first empire and what land did that empire include
Akkadian Empire The Akkadian Empire reached its political peak between the 24th and 22nd centuries BC, following the conquests by its founder Sargon of Akkad.[7] Under Sargon and his successors, the Akkadian language was briefly imposed on neighboring conquered states such as Elam and Gutium. Akkad is sometimes regarded as the first empire in history, though the meaning of this term is not precise, and there are earlier Sumerian claimants.[8][9]
Persian Empire The Persian Empire (Persian: شاهنشاهی ایران, translit. Šâhanšâhiye Irân, lit. 'Imperial Iran') is a series of imperial dynasties centered in Persia/Iran since the 6th century BC in Achaemenid era, to the 20th century AD in Qajar era.
