On February 23, 1991, a military group by the name of the NPKC, or National Peace Keeping Council, which was composed of Military academy graduates, sought to overthrow the current government in Thailand, which they believed to be a “parliamentary dictatorship”. NPKC quickly gained control over the government and formed the political party known as Samakki Tham.
The government began planning to build a hydroelectric dam on the Mun River (also called the Moon, Mul, and Mool River but referred to henceforth only as Mun) in the early 1980s. In 1989, the government approved the plans. In 1991, construction of the dam began and was completed four years later in January 1995. Not only did the dam cost almost twice as much money as the Thai government originally predicted, but it also resulted in substantially more damage to the ecosystem than early studies suggested.
