パテート・ラーオ
The political wing of the Pathet Lao, called the "Lao Patriotic Front" () served in multiple coalition governments, starting in 1956. Through the 1960s and 1970s the Pathet Lao battled the Royal Lao government during the Laotian Civil War, gaining control of the north and east of Laos. The Pathet Lao gained power throughout the country by the spring of 1975. In December, the US-backed Vientiane government fell and the Lao People's Revolutionary Party formed a new government.
