Rebuilt Vietnam

Vietnam ( Vietnamese: Việt Nam), officially the Socialist Republic of Vietnam (Vietnamese: Cộng hòa xã hội chủ nghĩa Việt Nam), is the easternmost country on the Indochina Peninsula in Southeast Asia. It is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and the South China Sea to the east. With a population of over 86 million, Vietnam is the 13th most populous country in the world.

The people of Vietnam regained independence and broke away from China in AD 938 after their victory at the battle of Bạch Đằng River. Successive dynasties flourished along with geographic and political expansion deeper into Southeast Asia, until it was colonized by the French in the mid-19th century. Efforts to resist the French eventually led to their expulsion from the country in the mid-20th century, leaving a nation divided politically into two countries. Fighting between the two sides continued during the Vietnam War, ending with a North Vietnamese victory in 1975.

Việt Nam was adopted as the official name of the country by Emperor Gia Long in 1804. It is variation on "Nam Việt," (南越, Southern Việt) a name for the country used in ancient times. In 1839, Emperor Minh Mạng renamed the country Đại Nam ("Great South"). In 1945, the nation's official name was changed back to "Vietnam". The name is also sometimes rendered as "Viet Nam" in English.

The area now known as Vietnam has been inhabited since Paleolithic times, and some archaeological sites in Thanh Hoa Province purportedly date back several thousand years. Archaeologists link the beginnings of Vietnamese civilization to the late Neolithic, Early Bronze Age, Phung-nguyen culture, which was centered in Vinh Phuc Province of contemporary Vietnam from about 2000 to 1400 BCE. By about 1200 BCE, the development of wet-rice cultivation and bronze casting in the Ma River and Red River plains led to the development of the Dong Son culture, notable for its elaborate bronze drums. The bronze weapons, tools, and drums of Dongsonian sites show a Southeast Asian influence that indicates an indigenous origin for the bronze-casting technology. Many small, ancient copper mine sites have been found in northern Vietnam. Some of the similarities between the Dong Sonian sites and other Southeast Asian sites include the presence of boat-shaped coffins and burial jars, stilt dwellings, and evidence of the customs of betel-nut-chewing and teeth-blackening.

The legendary Hồng Bàng Dynasty of the Hùng kings is considered by many Vietnamese as the first Vietnamese state, known as Văn Lang. In 257 BCE, the last Hùng king lost to Thục Phán, who consolidated the Lạc Việt tribes with his Âu Việt tribes, forming Âu Lạc and proclaiming himself An Dương Vương. In 207 BCE, a Chinese general named Zhao Tuo defeated An Dương Vương and consolidated Âu Lạc into Nanyue. In 111 BCE, the Chinese Han Dynasty consolidated Nanyue into their empire.

For the next thousand years, Vietnam was mostly under Chinese rule. Early independence movements such as those of the Trưng Sisters and of Lady Triệu were only briefly successful. It was independent as Vạn Xuân under the Anterior Ly Dynasty between 544 and 602. By the early 10th century, Vietnam had gained autonomy, but not independence, under the Khúc family.

In 938 CE, a Vietnamese lord named Ngô Quyền defeated Chinese forces at the Bạch Đằng River and regained independence after 10 centuries under Chinese control. Renamed as Đại Việt, the nation went through a golden era during the Lý and Trần Dynasties. During the rule of the Trần Dynasty, Đại Việt repelled three Mongol invasions. Buddhism flourished and became the state religion. Following the brief Hồ Dynasty, Vietnamese independence was momentarily interrupted by the Chinese Ming Dynasty, but was restored by Lê Lợi, the founder of the Lê Dynasty. Vietnam reached its zenith in the Lê Dynasty of the 15th century, especially during the reign of Emperor Lê Thánh Tông (1460–1497). Between the 11th and 18th centuries, the Vietnamese expanded southward in a process known as nam tiến (southward expansion). They eventually conquered the kingdom of Champa and part of the Khmer Empire.

Towards the end of the Lê Dynasty, civil strife engulfed much of Vietnam. First, the Chinese-supported Mạc Dynasty challenged the Lê Dynasty's power. After the Mạc Dynasty was defeated, the Lê Dynasty was reinstalled, but with no actual power. Power was divided between the Trịnh Lords in the North and the Nguyễn Lords in the South, who engaged in a civil war for more than four decades. During this time, the Nguyễn expanded southern Vietnam into the Mekong Delta, annexing the Champa in the central highlands and the Khmer land in the Mekong. The civil war ended when the Tây Sơn brothers defeated both and established their new dynasty. However, their rule did not last long and they were defeated by the remnants of the Nguyễn Lords led by Nguyen Anh with the help of the French. Nguyen Anh unified Vietnam, and established the Nguyễn Dynasty, ruling under the name Gia Long.

Vietnam's independence was gradually eroded by France in a series of military conquests from 1859 until 1885 when the entire country became part of French Indochina. The French administration imposed significant political and cultural changes on Vietnamese society. A Western-style system of modern education was developed, and Christianity was propagated widely in Vietnamese society. Most of the French settlers in Indochina were concentrated in Cochinchina (southern third of Vietnam whose principal city was Saigon). Developing a plantation economy to promote the exports of tobacco, indigo, tea and coffee, the French largely ignored increasing calls for self-government and civil rights. A nationalist political movement soon emerged, with leaders such as Phan Boi Chau, Phan Chu Trinh, Phan Dinh Phung, Emperor Ham Nghi and Ho Chi Minh calling for independence. However, the French maintained control of their colonies until World War II, when the Japanese war in the Pacific triggered the invasion of French Indochina in 1941. This event was preceded by the establishment of the Vichy French administration, a puppet state of Nazi Germany then ally of the Japanese Empire. The natural resources of Vietnam were exploited for the purposes of the Japanese Empire's military campaigns into the British Indochinese colonies of Burma, the Malay Peninsula and India.
