Abstract:
The loss of Burmeses influence in Lanna around late c.18 to early c.19 brings opportunity for local chieftains in Lanna to gain their own independent. Nan in that era was under controlled of Luang Tin dynasty, which had successfully created their own sphere of influence and separated from other states in Lanna. However the chaos and destruction from previous wars still maintained and the status of Nan still unstable. To gained full stable and prosperity to their state, the rulers of Nan had to form a policy which suit and effectively for their petite state. This thesis aims to examine the cause, the process and the result from Nans ruler policy around 1786 1899. The research suggests that the rulers of Nan used a various relationship with their neighbor to gained a position in regional politic, used the decentralized policy for governed but still maintained in the highest hierarchy in their state to gained stability, and used a status of Siams tributary state to guarantee their position and status of ruler in Nan. The policies that had been used made the rulers of Nan successfully maintained their own state and status until 1899AD when Siam's central government started a reformation and transformation of authority.
