Unlike the other kingdoms within the Indian subcontinent, the Pallava empire of the southeastern coast of the India peninsula did not have culture restrictions on crossing the sea. Chola empire also had profound impact on Southeast Asia, who executed South-East Asia campaign of Rajendra Chola I and Chola invasion of Srivijaya. This led to more exchanges through the sea routes into Southeast Asia. Whereas Buddhism thrived and became the main religion in many countries of the Southeast Asia, it became a minority in India.
