Rama I was the founder of the Siamese (Thai) Chakri Dynasty, the dynasty which continues to reign in Thailand today. He took the throne in 1782.
In contrast to the Confucian and Chinese-influenced kingdoms in Korea, Vietnam, Ryukyu, and elsewhere, the king was seen as a bodhisattva, and as chakravartin, a universal monarch not as explicated in a Confucian cosmology, but rather in a Hindu/Brahminist one.
Despite this, rituals and protocols at the Chakri court came to be influenced by Chinese examples, and Siam regularly sent tribute to Qing Dynasty China, the Chinese Confucian worldview not being seen as too problematic nor as a challenge to Siam's heavily Indic-influenced political culture.
