The Philippines is the only country in Southeast Asia that was subjected to Western colonization before it had the opportunity to develop either a centralized government ruling over a large territory or a dominant culture. In ancient times the inhabitants of the Philippines were a diverse agglomeration of peoples who arrived in various waves of immigration from the Asian mainland and who maintained little contact with each other. Contact with Chinese traders was recorded in 982, and some cultural influences from South Asia, such as a Sanskrit-based writing system, were carried to the islands by the Indonesian empires of Srivijaya(7th–13th century) and Majapahit (13th–16th century); but in comparison with other parts of the region, the influence of both China and India on the Philippines was of little importance. The peoples of the Philippine archipelago, unlike most of the other peoples of Southeast Asia, never adopted Hinduism or Buddhism.
