The 200,000 Vietnamese troops supporting the PRK, as well as Khmer Rouge defectors, had ousted the Democratic Kampuchea regime of Pol Pot , and were initially welcomed by the majority of Cambodians as liberators. Some Khmer, though, recalled the two countries' historical rivalry and feared that the Vietnamese would attempt to subjugate the country, and began to oppose their military presence. Members of the KPNLF supported this view.

605-542: A conflict between two politicians: Son Sann and Ieng Mouly. According to sources, Sann and Mouly had been arguing about different topics for many years.

9559-699: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty .

The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt
9680-435: The difficult job of coordinating the actions of each unit. This understandably led to a lot of confusion and relative ineffectiveness for large-scale battles.

9801-414: The dispossession of native inhabitants .

11616-400: The non-communist resistance through USAID . Since its beginning, the KPNLF had depended on international financial aid to help maintain their civilian camps and carry out military operations.

11858-488: The other hand, for Abdul Gaffar Peang Meth and Hing Kunthorn, Sann believed that disciplinary action was necessary in order to rejoin the party.

However, the infighting continued because neither side had the power to defeat the other. As the months wore on, Thai authorities became concerned with
