The Lakhmid kingdom, also referred to as al-Manādhirah (المناذرة) or as Banū Lakhm, was an Arab kingdom that was founded and ruled by the Lakhmid dynasty from c. 268 to 602. Spanning Eastern Arabia and Southern Mesopotamia, it existed as a dependency of the Sasanian Empire, though the Lakhmids held al-Hira as their own capital city and governed from there independently. The kingdom was a participant in the Roman–Persian Wars, in which it fought as a Persian ally against the Ghassanid kingdom, which was ruled by a rival Arab tribe and existed as a dependency of the Roman Empire. While the term "Lakhmids" has been applied to this kingdom's ruling dynasty, more recent scholarship prefers to refer to them as the Naṣrids.
