The insurgency in Laos was a sporadic military conflict between the Lao People's Army, and Vietnam People's Army opposed primarily by members of the former "Secret Army" or the Hmong people as well as various other ethnic lowland Lao insurgencies in Laos, who have faced governmental reprisals due to Royal Lao and Hmong support for the American-led, anti-communist campaigns in Laos during the Laotian Civil War—which is an extension to the war itself. The North Vietnamese invaded Laos in 1958-59 and supported the communist Pathet Lao. It continued on the day after the end of the civil war with the Pathet Lao's capture of the Laotian capital Vientiane, who overthrew the Royal Kingdom of Laos and established a new government known as the Lao People's Democratic Republic.
