Introduction: "In present day people know the word thet-­kayit as a usage that refers to a date or year, but in the Kon-­baung Period, thet-­kayit was a word of dual meaning; it signified a dated contractual deed as well as the date or year. In Myanmar, the utilisation of the word thet-­kayit began during the Bagan Period (1044?1287) with the introduction of Buddhism to Myanmar society. (Toe Hla, 2014, 3-­5) Most Bagan inscriptions started with this word and it soon became customary to start almost all historical writings and chronicles with the word thet-­kayit. Eventually, the documents themselves became known as thet-­kayits and any sort of contract such as obligatory notes, loans, mortgages, disputes, court judgements, etc. were referred to as thet-­kayits. These documents are valuable sources that tell us about the social and economic life of ordinary people during the Konbaung period. The Konbaung rural people recorded the cases of money lending and other social affairs in these documents. From a deep analysis of these thet-­kayits, many aspects of every day life like social relations, administration, customs and traditions, and people?s economic life at that time can be described." .....Paper delivered at the International Conference on Burma/Myanmar Studies: Burma/Myanmar in Transition: Connectivity, Changes and Challenges: University Academic Service Centre (UNISERV), Chiang Mai University, Thailand, 24-­26 July 2015.
