:: Sukhothai Period (1238 - 1350 A.D.)

By the early 1200s the Thais had established small northern city-states in Lanna, Phayao and Sukhothai.  In 1238 two Thai chieftains, Khun Bang Klang Tao and Khun Pha Muang, successfully rebelled against Khom suzerainty and established the first truly independent Thai kingdom in Sukhothai a kingdom that was short-lived but of immense cultural importance to the nation's history.

The Sukhothai period saw the Thais' gradual expansion throughout the entire Chao Phraya River basin, and the establishment of Theravada Buddhism as the paramount Thai religion. It was here that the first evidence of written Thai was left, along with distinctively Thai styles of art such as painting, sculpture, architecture, and literature, which survived after the Kingdom of Sukhothai was absorbed by the kingdom of Ayutthaya a dynamic young kingdom further to the South, in the Chao Phraya River valley.

:: Ayutthaya Period (1350 - 1767 A.D.)


During Ayutthaya 's 417 years as the capital, under the rule of 34 kings, the Thais not only brought their distinctive culture to full fruition, but totally rid their lands of the Khom presence, fostering contact with Arabian, Indian, Chinese, Japanese and European powers.  Contact with the West, especially, flourished during the reign of King Narai the Great (1656-1688), in which an envoy was sent to France to establish foreign diplomatic contacts.  Founded in 1350, Ayutthaya remained the Thai capital until it was sacked and burned by the Burmese in 1767.

:: The Thonburi Period Tak Sin (1767 - 1782 A.D.)


Ayutthaya 's downfall was a severe blow to the Thais. However, a Thai revival occurred within a few months, and the Burmese were expelled by King Taksin, who ushered in the Thonburi Period (1767-1782).  King Taksin made Thonburi the capital, but it was the shortest-lived capital in Thai history.  In 1782, the first king of the present Chakri dynasty, Rama I, established his new capital on the site of a riverside hamlet called Ban Kok (Village of the Wild Plums).

:: Rattanakosin Period (1782 - present) 

During the Rattanakosin Period (1782 present), two Chakri monarchs, King Mongkut (Rama IV), who reigned between 1851 and 1868, and his son King  Chulalongkorn (Rama V, 1868-1910), saved Thailand from the powerful tide of  Western colonialism that was sweeping the region, through adroit diplomacy and selective modernization. 

Today, Thailand is a modern constitutional monarchy.  Since 1932, Thai kings, including the present monarch H.M. King Bhumibol Adulyadej (Rama IX), have exercised their legislative powers through a national assembly, their executive powers through a cabinet headed by a prime minister and their judicial powers through the courts of law.
