The Orontids established their supremacy over Armenia around the time of the Scythian and Median invasion in the 6th century BC.[11] Its founder was Orontes I Sakavakyats (Armenian: Երվանդ Ա Սակավակյաց, Yervand I Sakavakyats). His son, Tigranes Orontid, united his forces with Cyrus the Great and killed Media's king. Moses of Chorene called him "the wisest, most powerful and bravest of Armenian kings."
