King Ram Khamhaeng (flourit. late 13th century) gave royal support to the Lankavong Theravāda monks in Nakon Sri Thammarath. He invited them to his capital, built monasteries for them and subsequently sent more monks Sri Lanka to study. This royal support increased the prestige and influence of Theravāda in Thailand. During Ram Khamhaeng's reign, stupas were built which reflect the Sri Lankan influence. One of these is Wat Chang Lom. Thai travelers to Sri Lanka also brought back the root of a Bodhi tree, which began the Thai tradition of venerating Bodhi trees. Sukhothai style Buddha statues also reflect Sri Lankan art styles.
