Objective The objective of this thesis is to study Buddhism in the Sukhodaya Period in detail : to compile all the documents and other sources concerning this subject matter and to study the issues which have never been touched before. Research method All the information and background knowledge on the thesis topic from stone inscriptions, history, mythology both in Thai and Pali and Sanskrit are gathered, then analyzed and concluded together with the additional information from the authorities. Conclusion Buddhism in the period of Sukhodaya prospered exceedingly. There were a large number of monks who had profound knowledge of Tripitaka and who were very strict disciplinarians highly respected by the people. The Sukhodaya people were proper Buddhists. They observed the eight commandments, did merits, gave alms, and took into account the building and maintaining of the monasteries. In comparison, many Buddhist traditions of the Sukhodaya Period and of our times have both similarities and differences in the mastery of the Tripitaka and in the monk’s and the people’s conduct. Suggestions for further study. This thesis is a pioneering step; therefore, there are many points which should be pursued such as Pali Buddhist literature and comparative studies of Buddhism in the Sukhodaya period and in the other periods.
