An Analysis of Siamese Power Consolidation in the Isan Region after the Anouvong's Rebellion 1826

Abstract

   This research article aims to: 1. examine the significance of the Chao Anouvong Rebellion and its impact on the political policy changes of Siam in the Isaan region, and 2. explore Siam's actions to expand its power in the Isaan region following the Chao Anouvong Rebellion of 1826. The study employs a historical approach and documentary research methodology.   The research findings reveal that the Chao Anouvong Rebellion made Siam aware of the weaknesses in its control over the Isaan region, due to a fragile political structure and a lack of stable governance. Specifically, issues related to the autonomy of local power groups, personal conflicts, and the struggle for resources led to a weakened system of local governance and self-defense when crises arose. This, in turn, prompted Siam to revise its administrative policies to consolidate power by more rigorously intervening in and controlling the Isaan region. The changes involved territorial management, such as adjusting the authority boundaries of various cities, direct control over city establishments, and the creation of a balance of power within the region. Siam also implemented governance mechanisms, including sending central officials to work in the region, monitoring manpower, and addressing the tribute system. These measures formed the foundation for Siam's subsequent annexation of the Isaan region as part of the modern state.
