The Sukhothai Kingdom was first established as a small Kingdom. The glory days of the Kingdom were during the reign of King Ramkhamhaeng the Great. The Kingdom was bounded by Lamphun to the north, by Dong Pyha Yen Mountain Range and Panomdongrak Mountain to the northeast, by Hongsawadee to the west and by the Malaya Peninsula to the south. The Kingdom remained independent throughout the reign of 6 kings, then reached its nadir and was finally annexed to Ayutthaya Kingdom in the reign of Phya Sai Leu Thai who lost a battle to King Boromracha the First in 1378. 2 kings of the Phra Roung Dynasty continued reigning Sukhothai until 1438 which was the end of this dynasty.

Sukhothai's administrative regime was a "Father-Son" system or a "paternalistic" system. That is, the King was like a father, while public servants were like his children or family members, ruling in a hierarchical pattern. Professor James N. Mosel commenting on Sukhothai's administrative regime, says that there were 2 significant characteristics, namely, the Father-Son system and colonial provincial towns which was similar to a system of Lords. Prof. Mosel emphasizes that Thai colonial provincial town administration or the lord system was different from the European model. However, according to a lecture by Somdetch Phra Chao Baromma Wong Ther Krom Praya Damrongraachanupap's, during the Sukhothai period, Kings were respected as the father to all the people. The Administration followed a family administration. The Father governed a number of houses and the people under the administration were thus his children. Houses formed into towns. Colonial provincial towns were under the King's control while dominions were under the control of their own lords and subject to the King's rule (Father King ). All government servants were called the King's Children. The father-son administration system was used as Thailand's administrative system until the change of administration regime. The term "father-son" system is highly significant and had great influence on the Thai people. Kings of the early Sukhothai period often called themselves Father King (Po-Khun) until it changed to Phya due to Cambodian influence which ended the father and son relationship between the King and his people and turned the relationship into one of master and slave.

The Father-Son Administration gave kings absolute power as fathers. If we consider this matter carefully, we can see that if the ruler, the King, adhered to the Code of Morality of Kings, protecting people like their own children, the people would therefore be happy. But if the administration was a master-slave system, the safety of people would be meaningless. However, the selection of an appropriate administration system depends on different circumstances and situations in different periods of time. The selection of a Father-son administrative system should seriously take into account the administration policies.

Under democratic regimes, to successfully achieve this ideology depends on many changes. The notion of the people that they are the rulers' children who need to be nurtured and supported all the time can make them lack political responsibility and sufficient awareness to inculcate themselves with democracy. The situation would also be difficult on the ruler's side since they have to take the role of protecting and directing the needs of the people. This also made democratic ideology difficult to be realized.
