After the advent of Islam in the Arabian Peninsula in the 7th century, Islam started its expansion towards eastern regions through trade encouraged by the development of the maritime Silk Roads. Muslims were known to have a commercial talent notably encouraged by Islam, as well as excellent sailing skills. Thus, they could monopolize the East-West trade of the maritime Silk Roads, connecting various major ports of eastern Asian regions together. Indeed, their commercial ships had to halt at various ports to be supplied with water and food, be repaired, or to wait for changes in wind direction.
These interactions resulted in further expansion of Islam to the people living in important coastal cities in the Indian Subcontinent, China, or in the more distant South-eastern islands of modern Indonesia or Philip.
