context_page_description: The Lan Na or Lan Na Kingdom, also known as Lannathai, was an Indianized state centered in present-day Northern Thailand from the 13th to 18th centuries.
  The cultural development 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 Lan Na 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. In 1775, Lan Na chiefs left the Burmese control to join Siam, leading to the Burmese–Siamese War.
  Following the retreat of the Burmese force, Burmese control over Lan Na came to the end. Siam, under King Taksin of the Thonburi Kingdom, gained control of Lan Na in 1776. From then on, Lan Na became a tributary state of Siam under the succeeding Chakri Dynasty.
context_section_description: The Lan Na kingdom was strongest under Tilokkarat (1441–1487). Tilokkarat seized the throne from his father Sam Fang Kaen in 1441. Tilokkarat's brother, Thau Choi, rebelled to reclaim the throne for his father and sought Ayutthayan support. Borommaracha II sent his troops to Lan Na in 1442 but was repelled and the rebellion was suppressed. Tilokkarat conquered the neighboring Kingdom of Payao in 1456.
  To the south, the emerging Kingdom of Ayutthaya was also growing powerful. Relations between the two kingdoms had worsened since the Ayutthayan support of Thau Choi's rebellion. In 1451, Yutthitthira, a Sukhothai royal who had conflicts with Trailokanat of Ayutthaya, gave himself to Tilokkarat. Yuttitthira urged Trilokanat to invade Pitsanulok which he had claims on, igniting the Ayutthaya-Lan Na War over the Upper Chao Phraya valley (i.e. the Kingdom of Sukhothai). In 1460, the governor of Chaliang surrendered to Tilokkarat. Trailokanat then used a new strategy and concentrated on the wars with Lan Na by moving the capital to Pitsanulok. Lan Na suffered setbacks and Tilokkarat eventually sued for peace in 1475.
  Tilokkarat was also a strong patron of Theravada Buddhism. In 1477, the Buddhist Council to recompile the Tripitaka was held near Chiang Mai. Tilokkarat also built and rehabilitated many notable temples. Tilokkarat then expanded west to the Shan States of Laihka, Hsipaw, Mong Nai, and Yawnghwe.
