The Thai political and public administration system of the King Trailokanat
had the main objective of categorizing cities of the State in order to rule and control
rather than to provide public services. The power of the State was centralized. The
Kings were the supreme head of State as absolute monarchy was the political system.
The Kings were not only the ruler but also God. Thus, political and public
administration reforms were based on rulers not the people. This system continued
until the public sector reform of King Chulalongkorn at the end of the 19th century.
