Praphas Charusathien

Praphas Charusathien (, , ; 25 November 1912 – 18 August 1997) was a Thai military officer and politician. He was a field marshal of the Royal Thai Army and minister of interior in the governments of military rulers Sarit Thanarat and Thanom Kittikachorn.

Personal life and education Praphas graduated from the Chulachomklao Royal Military Academy and became an infantry officer. He was sponsored by Field Marshal and Prime Minister-to-be Sarit Thanarat. He was quickly promoted to higher ranks. In 1957, Sarit appointed him minister of interior, a position in which he continued to serve after Sarit's death in 1963. The new prime minister was Thanom Kittikachorn, whose son married Praphas' daughter. From 1963 to 1973, he was additionally deputy prime minister and Commander-in-Chief of the Royal Thai Army. During this time, Praphas was the strong man in the background who pulled the strings in the Thanom government. He was known for obscure financial transactions and political intrigues, while sitting on the boards of 44 companies.

In 1973, he was replaced as army commander by Gen.Krit Srivara, which signaled his loss of influence. In October 1973 protests against the rigid military rule grew into a massive popular uprising that was answered by a bloody crackdown on the protesting students and democracy activists. The many dead civilians prompted King Bhumibol Adulyadej to intervene. Praphas, Thanom and his son-in-law Col.Narong Kittikachorn went into exile. 1955 - Grand Officer of the Order of Orange-Nassau
