Darius the Great

Darius I was the third king of the Persian Achaemenid Empire. Also called Darius the Great, he ruled the empire at its peak, when it included much of West Asia, the Caucasus, Central Asia, parts of the Balkans, portions of north and northeast Africa including Egypt, eastern Libya, coastal Sudan, Eritrea, as well as most of Pakistan, the Aegean Islands and northern Greece / Thrace-Macedonia. Darius ascended the throne by overthrowing Gaumata, the alleged magus usurper of Bardiya with the assistance of six other Persian noble families; Darius was crowned the following morning. The new king met with rebellions throughout his kingdom and quelled them each time.
