The Lan Na or Lanna Kingdom ("Kingdom of a Million Rice Fields"; Thai: อาณาจักรล้านนา, RTGS: Anachak Lan Na; Burmese: ဇင်းမယ် ပြည် or ယွန်းပြည်) was an Indianised state centered in present-day Northern Thailand from the 13th to 18th centuries. The Pali chronicles refers to the kingdom as Yonarattha or Yonkarattha (Kingdom of the Yuon) or of Bingarattha (Kingdom of the Mae Ping). In the Chinese History of the Yuan it is called Pa-pai-si-fu, mentioned first in 1292.
The cultural development of the people of the Northern Thai people had begun long before as successive kingdoms preceded Lan Na. As a continuation of the kingdom of Ngoenyang, Lan Na emerged strong enough in the 15th century to rival the Ayutthaya Kingdom, with whom wars were fought. However, the Lanna Kingdom was weakened and became a tributary state of the Taungoo Dynasty in 1558. Lan Na was ruled by successive vassal kings, though some enjoyed autonomy. The Burmese rule gradually withdrew but then resumed as the new Konbaung Dynasty expanded its influence. Taksin of the Thonburi Kingdom finally conquered Lan Na in 1775 and broke it down into a number of tributary kingdoms.
