Al-Ghamr ibn Yazid

Al-Ghamr ibn Yazid ibn Abd al-Malik (الغمر بن يزيد; ) was an Umayyad prince and commander. He led the last Umayyad campaign against the Byzantine Empire in 743.

Family
Al-Ghamr was the son of the Umayyad caliph Yazid II ((r. 720 – 724)). He owned extensive estates around Harran and resided in the desert castles of al-Muwaqqar, Qasr Kharana and Dhu Khushub in the Balqa (Transjordan). He was a younger brother of Caliph al-Walid II ((r. 743 – 744)), with whom he had good relations. Anecdotes recorded in the 10th-century Kitab al-aghani, have al-Ghamr and al-Walid spending time imbibing wine and being entertained by singers at the monastery of Deir Murran at the foot Mount Qasioun near Damascus. Al-Ghamr introduced to al-Walid the poet Muti ibn Iyas and secured the caliph's favor with another poet, Malik ibn Abi Samh. Later, both al-Ghamr and al-Walid carried the bier of the famous singer Ma'bad ibn Wahb during his funeral at the palace of Khirbat al-Mafjar in the Jordan Valley.

Raids against the Byzantines
Al-Ghamr served as a commander in one of the largest campaigns undertaken against the Byzantines during the reign of his uncle, Caliph Hisham ((r. 724 – 743)). The overall head of the campaign, al-Ghamr's cousin Sulayman ibn Hisham, dispatched him with 10,000 horsemen to ambush Byzantine forces in western Anatolia, while the governor of Malatya, Malik ibn Shu'ayb, and the commander Abdallah al-Battal, led separate forces, reaching as far as Akroinon. Sulayman and his troops came in as a rear guard. In the end, the campaign, while wreaking devastation on the inhabitants of Anatolia and their property, did not result in the capture of any forts or territory. While al-Ghamr and Sulayman returned safely to Syria, Malik and Abdallah al-Battal were both slain.

In 743, Caliph al-Walid II appointed al-Ghamr to command the annual summer campaign against the Byzantines. It also ended without the capture of any territory or forts, but al-Ghamr took several prisoners. It was the first and only campaign of al-Walid II's reign and the final campaign against the Byzantines under the Umayyads.

Death
After al-Walid II was assassinated in the Third Muslim Civil War, the powerful Umayyad governor of the northern frontier, Marwan II, demanded al-Ghamr take revenge against the conspirators, who included rival Umayyad princes. When the Umayyads were toppled in 750 by the Abbasids, many were massacred at an estate at Nahr Abi Futrus in Palestine. Al-Ghamr was among them but due to his friendship with the Abbasid general Abdallah ibn Ali, he was given the dignity of dying by the sword, rather than being bashed to death like the other Umayyads.

According to Ibn al-Abbar, the father and namesake of the Rustamid dynasty, which ruled part of the Maghreb in 777–909, was a mawla (client) of al-Ghamr.
