Cambyses II and the Conquest of Egypt

Cambyses II, son and successor of Cyrus the Great, reigned between 530 and 522 BCE. His chief military achievement was the conquest of Egypt in 525 BCE, after defeating Pharaoh Psamtik III at the Battle of Pelusium. With this conquest, Egypt became a Persian satrapy, integrated into the Achaemenid Empire as the Twenty-Seventh Egyptian Dynasty according to the traditional chronology of Manetho.
