The people of Vietnam speak Vietnamese which is a tonal monosyllabic Mon–Khmer language as an official national language. In its early history, Vietnamese writing used Chinese characters. In the 13th century, the Vietnamese developed their own set of characters called Chữ nôm. The celebrated epic Đoạn trường tân thanh (Truyện Kiều or The Tale of Kieu) by Nguyễn Du was written in Chữ nôm. During the French colonial period, Quốc ngữ, the romanized Vietnamese alphabet used for spoken Vietnamese, which was developed in 17th century by Jesuit Alexandre De Rhodes and several other Catholic missionaries, became popular and brought literacy to the masses.
Various other languages are spoken by several minority groups in Vietnam. The most common of these are Tày, Mường, Cham, Khmer, Chinese, Nùng, and H'Mông. The Montagnard peoples of the Central Highlands also speak a number of distinct languages. The French language, a legacy of colonial rule, is still spoken by some older Vietnamese as a second language, but is losing its popularity.

Historically, Vietnam has been an agricultural civilization based on wet rice cultivating. The Vietnam War destroyed much of the country's economy. Upon taking power, the Government created a planned economy for the nation.

For a decade, united Vietnam's economy was plagued with inefficiency and corruption in state programs, poor quality and underproduction and restrictions on economic activities and trade. It also suffered from the trade embargo from the United States and most of Europe after the Vietnam War. Subsequently, the trade partners of the Communist blocs began to erode.

Private ownership was encouraged in industries, commerce and agriculture.[55]

The pro-Hanoi Vietcong began a guerrilla campaign in the late 1950s to overthrow Diem's government, which an official Vietcong statement described as a "disguised colonial regime."[31] In the North, thousands of landowners were murdered by the communists and famine broke out in the 1950s. In the South, Diem went about crushing all opposition and tens of thousands were jailed or killed; dissidents were routinely labelled as communists even if they were anti-communist. Both Vietnams were police states with totalitarian security systems.

In 1963, Buddhist discontent with Diem's pro-Catholic discrimination erupted following the banning of the Buddhist flag and the Hue Vesak shootings. This resulted in a series of mass demonstrations during what is known as the Buddhist crisis. With Diem unwilling to bend, Nhu orchestrated the Xa Loi Pagoda raids; estimates of the death toll range into the hundreds. As a result, America's relationship with Diem broke down and resulted in the 1963 coup that saw Diem killed.
