Chiang Mai sometimes written as "Chiengmai" or "Chiangmai", is the largest city in northern Thailand. It is the capital of Chiang Mai Province and was a former capital of the Kingdom of Lan Na (1296–1768), which became the Kingdom of Chiang Mai, a tributary state of Siam from 1774 to 1899 and finally the seat of a merely ceremonial prince until 1939. It is 700 km (435 mi) north of Bangkok and is situated amongst the highest mountains in the country. The city sits astride the Ping River, a major tributary of the Chao Phraya River. Chiang Mai means "new city" and was so named because it became the new capital of the Lan Na kingdom when it was founded in 1296, succeeding Chiang Rai, the former capital founded in 1262.
Chiang Mai gained prominence in the political sphere in May 2006, when the Chiang Mai Initiative was concluded between the ASEAN nations and the "+3" countries (China, Japan, and South Korea). Chiang Mai was one of three Thai cities contending for Thailand's bid to host the World Expo 2020 (the others were Chonburi and Ayutthaya). Ayutthaya, however, was the city ultimately chosen by the Thai Parliament to register for the international competition.
Chiang Mai has positioned itself to become a Creative City and is considering applying for Creative City status with UNESCO. Chiang Mai was one of two tourist destinations in Thailand on TripAdvisor's 2014 list of "25 Best Destinations in the World", where it stands at number 24.
