History

Before the ''Thesaphiban'' reforms, the country consisted of partially independent cities called ''
mueang'', some directly subordinate to the capital, some subordinate to larger ''mueang'', or to one or more of the
tributary kingdoms. Before the reforms,

s inherited their posts from their family lineage, and lived on taxes they collected in their area, a practice formally called
tax farming. These were converted from hereditary governors to appointed governmental posts, as had been done by Chinese
Yuan,
Ming, and
Qing-era rulers in first recognizing
Tusi (tribal leaders) as imperial officials, then replacing them with imperial appointees. The arrangement resulted in governors being appointed and paid by the central government, and ''mueang'' developed into
provinces

. An essential step in the ending of tax farming was the creation on 3 September 1885 of the
Royal Survey Department. Though its first fruits were not obtained until 1901, the department's

. The term ''changwat'' (จังหวัด) for the provinces was first used in 1907 for the provinces in Monthon Pattani, and by 1916 had come into general use.
Resistance to reform
It took till around 1910 to implement the system throughout the country. The main reason for the slow implementation was the lack of suitably educated officials, but also the resistance of the traditional local leaders, which recalled the 1768–1770 resistance of the monk Chao Phra Faang to
Thonburi reestablishment of Siamese authority. In 1902 along both banks of the
Mekong, local revolts ( ) led by charismatic religious leaders called ''holy man'' or () broke out. The most serious of these was led by east-bank rebel
Ong Keo against French authority in the former Thai tributary
kingdom of Champasak. On the west bank in the area of
Ubon Ratchathani, a less-well known former monk and ''phi bun'' headed a
millenarian sect inspired by his
apocalyptic prophecies, which spread
fear, uncertainty and doubt among almost all the peoples along both banks of the river. The Bangkok government put down west bank resistance with little use of force, and cooperated with
French Indochina

officials insofar as limiting Thai authority to the west bank, later called
Isan. East bank resistance however had no definitive end and became subsumed into the
Second Indochina War.
Far from the Mekong, resistance to reform continued into the 21st century in the

Further development
In 1915 there were 19 monthons containing 72 provinces. Due to economic problems, several monthon were merged in 1925. Monthon Phetchabun had been dissolved in 1915. Only 14 monthon remained: Ayutthaya, Bangkok (Krung Thep), Chanthaburi, Nakhon Chaisi, Nakhon Ratchasima, Nakhon Sawan, Nakhon Si Thammarat, Pattani, Phayap, Phitsanulok, Phuket, Prachinburi, Ratchaburi, and Udon Thani. In 1932 another four were abolished: Chanthaburi, Nakhon Chaisi, Nakhon Sawan, and Pattani.
Finally in 1933 the whole monthon system was abolished by the ''Provincial Administration Act 2476 B.E./A.D. 1933'', part of the changes made after the
coup d'état

, which changed from an absolute to a constitutional monarchy, and the 70 provinces to second-level administrative divisions.
