Burma is located in the northwestern part of Indochina. It is bordered by the People’s Republic of China in the northeast, Laos and Thailand in the southeast, Bangladesh in the west, India in the northwest, and the Bay of Bengal to the southwest, with the Andaman Sea defining its southern periphery.
It was known by that name until 1989, and afterwards it was called "Republic of the Union of Myanmar". The proportion of Muslims there is 20%.

Islam was introduced into Burma also through trade. Some Arab-Muslim merchants landed on the coasts of Burma. However, it seems that the spread of Islam through sea was very little and insignificant in Burma; because the Burmese coasts did not have suitable ports in which ships can dock. The trade ships often took a short trade route to Malacca and Southeast Asia. Therefore, the spread of Islam through trade was on a larger scale in southern Burma, Pattani, and the Malays.

Muslim Tatars invaded Burma through China in 686 AH, and this led to the spread of Islam in Burma. Muslims of Burma deposed the tyrant king and installed another king, who was less unjust than his predecessor.

Islam also reached Burma through India, in the 11th century AH. During the rule of Aurangzeb, a disagreement occurred between him and his brother Shuja, who fled to Arakan (in present-day Burma) with a number of his Muslim followers after leading a failed coup. These Muslims mingled with the people of Burma and penetrated into the indigenous population, spreading their religion there. A number of Muslims from China and India came to Burma as well and settled there.

Burmese Muslims were persecuted by the British occupation and were denied the right to hold governmental jobs and work in general. The persecution grew intense and more serious after independence. Muslims of Burma were recently subjected to genocide that claimed the lives of many people and forced many others to flee for their lives. Large influxes of Muslims fled from Burma to neighboring countries, especially Bangladesh.
The majority of Muslims are concentrated in one area, which is Arakan, located in the north-west of Burma. During the rule of the ‘Abbasid Caliph Haaroon Ar-Rasheed (170 -193 AH), Islam reached Burma also by Arab traders. Burma became an independent country and was ruled by 48 consecutive Muslim kings, the first of which was Sultan Sulaymaan Shah. Muslim kings ruled Burma for more than three and a half centuries, between the years 834 AH/ 1430 AD and 1198 AH/1784 AD.
