Mazun was a Sasanian province in Late Antiquity, which corresponded to modern dayBahrain, Qatar, United Arab Emirates, and the northern half of Oman. The province served as a Sasanian outpost, and played an important role in the Sasanian efforts to gain control over the Indian Ocean trade, and to establish their dominance in the wealthy regions of Hadramaut and Yemen. In the 6th-century, the province was ruled by the clients and allies of the Sasanians, the Lakhmids.
History
was in c. 240 conquered by Ardashir I, who made it into the province of Mazun. According to the 8th-century Šahrestānīhā ī Ērānšahr, Ardashir appointed a certain Oshag of Hagar as marzban over the "Do-sar and Borg-gil by the wall of the Arabs." He also deported the prominent Azd tribe from Oman to Shihr on the Hadhramaut coast. During the childhood of shah Shapur II, Arab nomads made several incursions into the Sasanian homeland of Pars, where they raided Gor and its surroundings. Furthermore, they also made incursions into Meshan and Mazun. At the age of 16, Shapur II led an expedition against the Arabs; primarily campaigning against the Iyad Iyad tribe in Asoristan and thereafter he crossed the Persian Gulf, reaching eastern Arabia. He proceeded to attack the Banu Tamim in the Al Hajar Mountains. Shapur II reportedly killed a large number of the Arab population and destroyed their water supplies by stopping their wells with sand. After having dealt with the Arabs of eastern Arabia, he continued his expedition into western Arabia and Syria, where he attacked several cities—he even went as far as Medina. Because of his cruel way of dealing with the Arabs, he was called Dhū l-Aktāf "he who pierces shoulders" by them. Not only did Shapur II pacify the Arabs of the Persian Gulf, but he also pushed many Arab tribes further deep into the Arabian Peninsula. Furthermore, he also deported some Arab tribes by force; the Taghlib to Bahrain and Hatta; the Banu Abdul Qays and Banu Tamim to Hagar; the Banu Bakr to Kirman, and the Banu Hanzalah to a place near Hormizd-Ardashir. Sasanian garrisons were established in Oman's strategic coast in Al Batinah Region, including the tip of the Musandam Peninsula, Sohar, and Rustaq. Shapur II, in order to prevent the Arabs from making more raids into his country, ordered the construction of a wall near al-Hirah, which became known as war-i tāzigān. With Eastern Arabia more firmly under Sasanian control, and with the establishment of Sasanian garrison troops, the way for Zoroastrianism was opened. Pre-Islamic Arabian poets often makes mention of Zoroastrianism practices, which they must have either made contact with in Asoristan or Eastern Arabia. In c. 531/2, shah Khosrow I appointed the Lakhmid king al-Mundhir III ibn al-Nu'man as the ruler of Mazun. A late Sasanian fort is recently excavated in Fulayj, Oman.
