History

King Mengrai founded the city of Chiang Mai (meaning "new city") in 1296, and it succeeded Chiang Rai as capital of the Lanna kingdom. The ruler was known as the Chao. The city was surrounded by a moat and a defensive wall, since nearby Burma was a constant threat. With the decline of the Lannathai kingdom, the city lost importance and was often occupied either by the Burmese or Thais from Ayutthaya. Because of the Burmese wars that culminated in the fall of Ayutthaya in April 1767, Chiang Mai was abandoned between 1776 and 1791. Lampang then served as the capital of what remained of Lannathai. Chiang Mai formally became part of Siam in 1774 by an agreement with Chao Kavila, after the Thai King Taksin helped drive out the Burmese. Chiang Mai then slowly grew in cultural, trading and economic importance to its current status as the unofficial capital of northern Thailand, second in importance only to Bangkok.

The inhabitants speak Kham Muang (also known as Northern Thai or Lanna) among themselves, though Central Thai is used in education and is understood by everyone. English is used in hotels and travel-related businesses and many educated people speak English.[2] The Kham Muang alphabet is now studied only by scholars, and Northern Thai is commonly written with the standard Thai alphabet.

The modern municipal dates to a sanitary district (sukhaphiban) that was created in 1915. This was upgraded to a municipality (thesaban) on March 29 1935, as published in the Royal Gazette, Book No. 52 section 80. First covering just 17.5 km2 (7 sq mi), the city was enlarged to 40.216 km2 (16 sq mi) on April 5, 1983.
