The Kingdom of Rattanatingsa, also known as the Kingdom of Chiang Mai, served as a subordinate state to the Siamese Rattanakosin Kingdom during the 18th and 19th centuries. It was later incorporated due to the centralizing reforms of Chulalongkorn in 1899. This kingdom succeeded the ancient Lanna kingdom, which had been dominated by the Burmese for two centuries until Siamese forces, led by Taksin of Thonburi, seized it in 1774. The Thipchak Dynasty governed this realm, and it was a tributary to Thonburi.
