Musel III Mamikonian

Mushegh III Mamikonian (Armenian: Մուշեղ Գ Մամիկոնյան) was an Armenian sparapet that fought against the Arabs during the Muslim conquest of Persia. He was killed during the Battle of al-Qādisiyyah in 636.

The family of Mushegh III Mamikonian is disputed. The Armenian historian Sebeos calls him a son of Davith Mamikonian. According to Christian Settipani, Davith was probably the son of Hamazasp, who was the son of Mushegh II Mamikonian. However, Cyril Toumanoff considers Davith as the son of Vahan II. Historians, however, agree that Mushegh was the elder brother of Hamazasp IV and Grigor I Mamikonian, who were both princes of Armenia.

In 636, Mushegh III, at the head of an army of 3000 men, and Novirak Grigor II, prince of Siunia, at the head of 1000 men, were the Armenian contingent who joined the army Rostam Farrokhzad, the spahbed of the Sasanian forces, who was preparing to fight the Muslim Arabs who were camping at Qādisiyyah.

Mushegh III, along with his two nephews, his sister's son, and his son Grigor II, died during the battle, including the Sasanian general Rostam Farrokhzad and a large part of the Sasanian army.

According to Cyril Toumanoff, and some other historians, Mushegh had a son named Mushegh IV Mamikonian, who was also a sparapet and prince of Armenia.
