History

Wat Si Sawai, Sukhothai Historical Park
Chiang Saen was established in the early 700 AD's at the same time,
Muang Sua (
Loungprabang) was established around 728 AD. Making Chiang Saen and Loungprabang the first Kingdoms established by the Tai speaking people in Southeast Asia. Precourser to the migration and expansion of the Tai speaking people into Northern Thailand, Laos, and eventually into Central Thailand and Central Laos.
The city of Sukhothai was part of the great
Khmer empire until
1238, when two
Thai chieftains, Pho Khun Pha Muang and Pho Khun Bang Klang Hao, declared their independence and established a Thai-ruled kingdom. Pho Khun Bang Klang Hao later became the first king of Sukhothai, calling himself Pho Khun Si Indrathit (or Intradit). This event traditionally marks the founding of the modern Thai nation, although other less well-known Thai kingdoms, such as
Lanna, Phayao and Chiang Saen, were established around the same time.

Sukhothai expanded by forming alliances with the other Thai kingdoms, adopting
Theravada Buddhism as the state religion with the help of
Ceylonese monks. Intradit was succeeded by his son Pho Khun Ban Muang, who was followed in
1278 by his brother, Pho Khun
Ramkhamhaeng. Under King Ramkhamhaeng the Great, as he is now known, Sukhothai enjoyed a golden age of prosperity. Ramkhamhaeng is credited with designing the
Thai alphabet (traditionally dated from
1283, on the evidence of the controversial
Ramkhamhaeng stele, an inscribed stone allegedly bearing the earliest known Thai writing). At its peak, supposedly stretching from Martaban (now in
Burma) to
Luang Prabang (now in
Laos) and down the
Malay Peninsula as far south as
Nakhon Si Thammarat, the kingdom's sphere of influence was larger than that of modern Thailand, although the degree of control exercised over outlying areas was variable.
After Ramkhamhaeng's death, he was succeeded by his son Loethai. The vassal kingdoms, first
Uttaradit in the north, then soon after the Laotian kingdoms of Luang Prabang and Vientiane (Wiangchan), liberated themselves from their overlord. In
1319 the
Mon state to the west broke away, and in
1321 Lanna placed
Tak, one of the oldest towns under the control of Sukhothai, under its control. To the south the powerful city of
Suphanburi also broke free early in the reign of Loethai. Thus the kingdom was quickly reduced to its former local importance only. Meanwhile,
Ayutthaya rose in strength, and finally in
1378 King Thammaracha II had to submit to this new power.

The Silajaruek Sukhothai are hundreds of stone inscriptions that form a historical record of the period. Among the most important inscriptions are Silajaruek Pho Khun Ramkamhaeng (Stone Inscription of King Ramkamhaeng), Silajaruek Wat Srichum (an account on history of the region itself and of Srilanka), and Silajaruek Wat Pamamuang (a Politico-Religious record of King Loethai).
Sukhothai became a tributary state of Ayutthaya between
1365 and
1378. In 1412 Ayutthaya installed a chief resident, and King Thammaracha IV was installed on the throne by Ayutthaya. Around 1430 Thammaracha moved his capital to
Phitsanulok, and after his death in
1438 the kingdom was reduced in status to a mere province of Ayutthaya.
