สภาพสังคมของเมืองจันทบุรีและเมืองตราดภายใต้การยึดครองของฝรั่งเศส จนถึงสิ้นสุดการปกครองแบบเทศาภิบาล พ.ศ. 2436-2476 / นวลมรกต ทวีทอง = Social context in Chanthaburi and Trad from the French occupation to the end of the "Thesaphiban" administrative system, 1893-1933 / Nualmorakot Taweethong
To study the history of social context in Chanthaburi and Trat during 1893 and 1933 and the research has found that when France occupied Chanthaburi during 1893 and 1904, France established the soldiers’ camps only within the city of Chanthaburi and at the Singha River. The Thai government still controlled over the administration. However, French occupation in Chanthaburi led to the deficiency of the government’s control on manpower and the collection of incomes since the Thai government had to change or mitigate its strict administration in order to help people. Although France only occupied some parts of Chanthaburi, its occupation affected the economic and social changes within Chanthaburi. It also promoted the expansion of economy, especially trading with Sai Ngon managed by the French. In addition, Chinese and Vietnamese people also applied to be French subjects in order to have "Privilege", to be protected by the French in terms of jurisdiction, to be the "pass" for facilitating the trading businesses, and to be the "channel" for tax avoidance. Furthermore, the research has discovered that the local people had the normal ways of living and their societies were not rapidly developed like in the city. For the social context in Trat, when France withdrew the soldiers from Chanthaburi and occupied Trat, the occupation caused the disorder and fear towards the people since the occupation of Trat was different from the Chanthaburi one. France had the authority to administer Trat through the appointment of the Cambodian ruler and French resident in order to control Trat’s administration. Regarding tax collection, France had the right to collect both import and export tax in Trat, therefore a lot of people from Trat migrated to Chanthaburi. This led to the problem that the Thai government needed to help and take care of such people with regards to their housing and land. After France withdrew the soldiers from Chanthaburi and Trat, the Thai government strengthened the administration of Monthol Chanthaburi under the "Thesaphiban" Administrative System, in order to be in compliance with the political condition at that time. After the Revolution in 1932, the government, thus, abolished the "Thesaphiban" Administrative System and issued the Siam Administration Rule 1933 in order to delegate the power to the provincial areas, and the provinces would be able to administer themselves more efficiently.
