Orodes II of Parthia

Orodes II (also spelled Urud II; Parthian: 𐭅𐭓𐭅𐭃 Wērōd), was King of Kings of the Parthian Empire from 57 BC to 37 BC. He was a son of Phraates III, whom he murdered in 57 BC, assisted by his elder brother Mithridates IV. The two brothers quickly fell out and entered into a dynastic struggle, in which Orodes was triumphant.

Meanwhile, the Roman general and triumvir Marcus Licinius Crassus had made an attempt to expand his share of Roman territory by eastward conquest. This attempt proved disastrous, with Crassus meeting his end in 53 BC, at the Battle of Carrhae, by Orodes' general Surena. Orodes himself had invaded Armenia and forced king Artavasdes II (r. 55–34 BC) to submit and abandon his alliance with the Romans. The victory at Carrhae secured for the Parthians the lands east of the Euphrates. Then, the next year they invaded Syria, but with little success. Surena, whose achievements had made him too dangerous, was killed by Orodes, and Pacorus I, the son and heir of the king was defeated by Cassius in 51 BC.
