This article aimed to explain the development of the Thai local politics and democracy which originated from the concept of the administration decentralization, and to promote the importance of democracy basic principles learning. In developed countries it is evident that the progress of politics and democracy experienced the processes of tolerance, majority rules and minority rights, conflict solving, negotiation, and benefits assimilation. The early stage of the initiation of the Thai local administration, under the District Administration Act of the year 1994 has also caused the conflicts and violence to life and properties, as well as crimes and corruptions of those involved with local politicians. However, the experience from the past two decades has led to the development of communities and local politicians resulting in the development of public utilities including roads, water supply, water sources, public spaces, public properties, and local economy. The centralized phenomena, including the number of votes in the elections, protests, and silence during the coup d’etat, reflected the failure and weaknesses of the national administration. Thus, the development of local administration can be considered as a good lesson in solving conflicts and violence in the nation's politics.
