Historical Note: Phraates IV, son of Orodes II, secured the Parthian throne after a violent struggle that saw the execution of several of his brothers. His reign was marked by ongoing conflict with Rome following Crassus’ disastrous campaign. In 20 BC, a peace settlement with Augustus restored the captured Roman standards, symbolizing a diplomatic victory for both powers. Despite his success, Phraates was ultimately poisoned by his Italian concubine Musa, who then placed their son Phraataces on the throne.
