The Banu Lakhm was an Arab tribe known primarily for its Nasrid (Lakhmid) ruling house, which governed as vassal kings under the Sasanian Empire from al-Hirah in modern Iraq during the 4th to 6th centuries CE. A branch of the tribe settled in Syria from the 4th century, allied with the Byzantine Empire, and later became part of the Umayyad Caliphate's Arab tribal forces in Palestine. The tribe largely remained Christian during the early Islamic period, with some members converting to Islam and integrating into the Muslim polity. Notable members include the Lakhmid kings such as Amr ibn Adi and al-Nu'man III, and the early Muslim convert Tamim al-Dari.
