Paerisades I (Greek: Παιρισάδης) also known as Birisades, Pairisades, and Parysades was a Spartocid king of the Bosporan Kingdom from 342 to 310/9 BC.
He was co-regent with Spartokos II when he ascended the throne, ruling as a governor over the minor parts of the kingdom, such as Theodosia,[1] due to him not being the eldest.
At some point during his reign, Paerisades possibly married his cousin Komosarye, a daughter of his uncle Gorgippos,[2] and they had four sons: Satyros II, likely named after his grandfather Satyros I, Eumelos, Gorgippos II,[3] also perhaps named after Komosarye's father and Paerisades' uncle, and Prytanis.
[7] He was also an active military leader, possibly taking Tanais and subjugating many tribes around the Maeotic Swamp and expanding the kingdom more than his father did in the Bosporan Expansion Wars, as well as waging war against the Scythians at some point during his reign.
Upon his death, Satyros II, Prytanis, and Eumelos engaged in the Bosporan Civil War because Eumelos had a claim to throne and was allied to Aripharnes while Satyros would not stand for it and waged war against his brother.
