Several Islamic kingdoms (sultanates) under both foreign and, newly converted, Rajput rulers were established across the north western subcontinent (Afghanistan and Pakistan) over a period of a few centuries. From the 10th century, Sindh was ruled by the Rajput Soomra dynasty, and later, in the mid-13th century by the Rajput Samma dynasty. Additionally, Muslim trading communities flourished throughout coastal south India, particularly on the western coast where Muslim traders arrived in small numbers, mainly from the Arabian peninsula. This marked the introduction of a third Abrahamic Middle Eastern religion, following Judaism and Christianity, often in puritanical form. Mahmud of Ghazni in the early 11th century raided mainly the north-western parts of the Indian sub-continent 17 times, but he did not seek to establish "permanent dominion" in those areas.
