Orodes defeated his brother Mithridates to become the Parthian king. In 53 BC Marcus Crassus invaded Parthia but was defeated and killed at the battle of Carrhae. During the Roman Civil War after Caesar's death, the Parthians, led by the king's son Pacorus, got their revenge by conquering Syria and much of Asia Minor. The Parthian forces were eventually defeated, however, and Pacorus was killed. Orodes appointed his next son Phraates as his heir, but Phraates deposed and killed him..
