Tây Ninh in the context of Long An province

The Viet Cong (VC) was an epithet and umbrella term to refer to the communist-driven armed movement and united front organization in South Vietnam. It was formally organized as and led by the National Liberation Front of South Vietnam, and conducted military operations under the name of the Liberation Army of South Vietnam (LASV). The movement fought under the direction of North Vietnam against the South Vietnamese and United States governments during the Vietnam War. The organization had both guerrilla and regular army units, as well as a network of cadres who organized and mobilized peasants in the territory the VC controlled. During the war, communist fighters and some anti-war activists claimed that the VC was an insurgency indigenous to the South that represented the legitimate rights of people in South Vietnam, while the U.S. and South Vietnamese governments portrayed the group as a tool of North Vietnam. It was later conceded by the modern Vietnamese communist leadership that the movement was actually under the North Vietnamese political and military leadership, aiming to unify Vietnam under a single banner.

North Vietnam established the National Liberation Front (NLF) on December 20, 1960, at Tân Lập village in Tây Ninh Province to foment insurgency in the South. Many of the VC's core members were volunteer "regroupees", southern Viet Minh who had resettled in the North after the Geneva Accord (1954). Hanoi gave the regroupees military training and sent them back to the South along the Ho Chi Minh trail in the late 1950s and early 1960s. The VC called for the unification of Vietnam and the overthrow of the American-backed South Vietnamese government. The VC's best-known action was the Tet Offensive, an assault on more than 100 South Vietnamese urban centers in 1968, including an attack on the U.S. embassy in Saigon. The offensive riveted the attention of the world's media for weeks, but also overextended the VC. Later communist offensives were conducted predominantly by the North Vietnamese. The organization officially merged with the Fatherland Front of Vietnam on February 4, 1977, after North and South Vietnam were officially unified under a communist government.

Caodaism is a Vietnamese monotheistic syncretic religion that retains many elements from Vietnamese folk religion such as ancestor worship, as well as "ethical precepts from Confucianism, occult practices from Taoism, theories of karma and rebirth from Buddhism, and a hierarchical organization from Catholicism". It was officially established in the city of Tây Ninh in Southern Vietnam in 1926.

The full name of the religion is Đại Đạo Tam Kỳ Phổ Độ (chữ Hán: 大道三期普度 'The Great Faith [for the] Third Universal Redemption').
