ヘタイロイ
In the northernmost part of ancient Greece, in the ancient kingdom of Macedonia, technological and organizational skills were forged with a long history of cavalry warfare. The "hetairoi" (Companion cavalry) was considered the strongest of their time. Under Alexander the Great, this force turned east, and in a series of decisive battles, it routed the Persian forces and took over as the dominant empire of the Mediterranean. Their Macedonia empire included present-day Greece, Bulgaria, Egypt, the Phoenician lands and many other basin regions of the Mediterranean and Asia Minor.
