Siamese-Vietnamese War in Cambodia 1841-1845

After the failure of Siam (Thailand) to regain hegemony over Cambodia, a Vietnamese-installed queen reigned on the Cambodian throne as her country increasingly came under the yoke of Vietnam. Vietnamese oppression caused a general uprising in 1841, with Cambodians slaughtering their Vietnamese overlords and others, soliciting help from Siam, and requesting Cambodian prince Ang Duong (1796-1860) to return from exile in Bangkok and become king. Siamese king Rama III (d. 1851) sent an army that installed Ang Duong on the Cambodian throne (1841). Vietnam, which had more than 50 garrisons throughout Cambodia, waged a savage four-year war against rural insurgents and Siamese troops, sustaining defeat in general but refusing to withdraw from the country. Finally, in 1845, both sides agreed to a compromise peace, which place Cambodia under joint Siamese and Vietnamese protection but with a Siamese predominance. In 1848, Ang Duong was formally crowned Cambodia's king.

Armed Conflict Events Database

Armed Conflict Events Data (ACED) is an research project providing independent information about known wars, international disputes, civil wars, rebellions, coups, revolutions, genocides and other violent conflicts. ACED has been online since December 2000. Various partial revisions and modifications have been implemented since then, however, the limitations of the this format hamper further development. During 2005, the decision was made to radically restructure the available conflict information into a database. The new Armed Conflict Events Database (ACEDb) will substantially increase the utility of available conflict data for students of military history. As well, it will offer expanded opportunities to add and edit records of conflict. Existing research material will be maintained in its present form but no revisions are planned. More news about the development of ACEDb may be found at News About the Armed Conflict Events Database. Feedback is welcome.
