Southern Thailand
Southern Thailand was the centre of Hinduism and Mahayana Buddhism. The Tang monk Yijing stopped at Langkasuka to study Pali grammar and Mahayana during his journey to India around 800. At that time, the kingdoms of Southern Thailand quickly fell under the influences of the Malay kingdom of Srivijaya from Sumatra. Rajendra Chola I of the Chola dynasty invaded the Tambralinga Kingdom in southern Thailand in the 11th century.
