Information: - Vietnam, officially the Socialist Republic of Vietnam (SRV), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants , it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. Vietnam is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, Thailand across the Gulf of Thailand to the southwest, and the Philippines, Malaysia and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976. - The Vietnam War, also known as the Second Indochina War, and known in Vietnam as Resistance War Against America or simply the American War, was a war that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China and other communist allies and the South Vietnamese army was supported by the United States, South Korea, Australia, Thailand and other anti-communist allies and the war is therefore considered a Cold War-era proxy war. - The People's Army of Vietnam (PAVN), also known as the Vietnamese People's Army, is the military force of the Socialist Republic of Vietnam. The PAVN is a part of Vietnam People's Armed Forces and includes: Ground Force (including Strategic Rear Forces), Navy, Air Force, Border Defence Force, and Coast Guard. However, Vietnam does not have a specific separate Ground Force or Army branch. All ground troops, army corps, military districts and specialised arms belong to the Ministry of Defence (Vietnam), directly under command of the Central Military Commission, Minister of Defence, and General Staff of the Vietnam People's Army. The military flag of the PAVN is the flag of the Socialist Republic of Vietnam, with the words "Quyt thng (Determination to win)" added in yellow at the top left. - The State of Vietnam was a state that claimed authority over all of Vietnam during the First Indochina War although part of its territory was actually controlled by the communist Viet Minh. The state was created in 1949 and was internationally recognized in 1950. Former emperor Bo i was chief of state ("Quc Trng"). After the 1954 Geneva Agreements, the State of Vietnam had to abandon the Northern part of the country to the Democratic Republic of Vietnam. Ngo inh Dim was appointed prime minister that same year, and after ousting Bo i in 1955, became president of the Republic of Vietnam. - North Vietnam, officially the Democratic Republic of Vietnam (DRV), was a state in Southeast Asia which existed from 1945 to 1976. Vietnamese revolutionary leader Ho Chi Minh declared independence from France on 2 September 1945 and announced the creation of the Democratic Republic of Vietnam. France reasserted its colonial dominance and a war ensued between France and the Viet Minh, led by Ho. The Viet Minh ("League for the Independence of Vietnam") was a coalition of nationalist groups, mostly led by communists. In February 1951, the communists announced the creation of the Lao ng Party (Labor Party), gradually marginalizing non-communists in the Viet Minh. - The Fall of Saigon was the capture of Saigon , the capital of South Vietnam , by the People 's Army of Vietnam and the National Liberation Front of South Vietnam ( also known as the Vit Cng ) on April 30 , 1975 . The event marked the end of the Vietnam War and the start of a transition period to the formal reunification of Vietnam under the Socialist Republic . North Vietnamese forces , under the command of General Vn Tin Dng , began their final attack on Saigon on April 29 , 1975 , with Army of the Republic of Vietnam ( ARVN ) forces commanded by General Nguyn Vn Toan suffering heavy artillery bombardment . This bombardment at the Tan Sn Nht Airport killed the last two American servicemen to die in Vietnam , Charles McMahon and Darwin Judge . By the afternoon of the next day , North Vietnamese troops had occupied the important points of the city and raised their flag over the South Vietnamese presidential palace . The South Vietnamese government capitulated shortly afterward . The city was renamed H Chi Minh City , after the Democratic Republic 's late President H Chi Minh . The capture of the city was preceded by the evacuation of almost all the American civilian and military personnel in Saigon , along with tens of thousands of South Vietnamese civilians associated with the southern regime . The evacuation culminated in Operation Frequent Wind , the largest helicopter evacuation in history . In addition to the flight of refugees , the end of the war and institution of new rules by the communists contributed to a decline in the city 's population . - The Indochina Wars were a series of wars fought in Southeast Asia from 1946 until 1989, between communist Indochinese forces against mainly French, South Vietnamese, American, Cambodian, Laotian and Chinese forces. The term "Indochina" originally referred to French Indochina, which included the current states of Vietnam, Laos and Cambodia. In use, it applies largely to a geographic region, rather than to a political area. The wars included: - The Vietnam People's Armed Forces (VPAF) are the armed forces of Vietnam. It consists of 3 components: Vietnam People's Army which is the military forces of Vietnam, Vietnam People's Public Security which is the security force of Vietnam and Vietnam Civil Defense Force which is the militia of Vietnam. - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed. - South Vietnam, officially the Republic of Vietnam was a state governing the southern half of Vietnam from 1955 to 1975. It received international recognition in 1949 as the "State of Vietnam" (194955), and later as the "Republic of Vietnam" (195575). Its capital was Saigon. The term "South Vietnam" became common usage in 1954, when the Geneva Conference provisionally partitioned Vietnam into communist and non-communist parts.
