Sogdianus

Sogdianus ( or ; Ancient Greek: Σογδιανός Sogdianos) was briefly a ruler of the Achaemenid Empire for a period in 424–423 BC. His short rule—lasting not much more than six months—and the little recognition of his kingdom are known primarily from the writings of Ctesias; who is known to be unreliable. He was reportedly an illegitimate son of Artaxerxes I by his concubine Alogyne of Babylon.
