Document 9: France–Vietnam relations: French -- Vietnamese relations started as early as the 17th century with the mission of the Jesuit father Alexandre de Rhodes. Various traders would visit Vietnam during the 18th century, until the major involvement of French forces under Pigneau de Béhaine from 1787 to 1789 helped establish the Nguyễn Dynasty. France was heavily involved in Vietnam in the 19th century under the pretext of protecting the work of Catholic missionaries in the country. France progressively carved for itself a huge colony, which would form French Indochina in 1887. France continued to rule Vietnam as a colony until France's defeat in the First Indochina War and the proclamation of Vietnam's independence in 1954.

Document 11: History of Vietnam: After Quang Trung's death, the Tây Sơn dynasty became unstable as the remaining brothers fought against each other and against the people who were loyal to Nguyễn Huệ's infant son. Nguyễn Ánh sailed north in 1799, capturing Tây Sơn's stronghold Qui Nhơn. In 1801, his force took Phú Xuân, the Tây Sơn capital. Nguyễn Ánh finally won the war in 1802, when he sieged Thăng Long (Hanoi) and executed Nguyễn Huệ's son, Nguyễn Quang Toản, along with many Tây Sơn generals and officials. Nguyễn Ánh ascended the throne and called himself Emperor Gia Long. Gia is for Gia Định, the old name of Saigon; Long is for Thăng Long, the old name of Hanoi. Hence Gia Long implied the unification of the country. The Nguyễn dynasty lasted until Bảo Đại's abdication in 1945. As China for centuries had referred to Đại Việt as Annam, Gia Long asked the Manchu Qing emperor to rename the country, from Annam to Nam Việt. To prevent any confusion of Gia Long's kingdom with Triệu Đà's ancient kingdom, the Manchu emperor reversed the order of the two words to Việt Nam. The name Vietnam is thus known to be used since Emperor Gia Long's reign. Recently historians have found that this name had existed in older books in which Vietnamese referred to their country as Vietnam.

Document 14: North Vietnam: After about 300 years of partition by feudal dynasties, Vietnam was again under one single authority in 1802 when Gia Long founded the Nguyễn dynasty, but the country became a French protectorate after 1883 and under Japanese occupation after 1940 during World War II. Soon after Japan surrendered on September 2, 1945, the Việt Minh in the August Revolution entered Hanoi, and the Democratic Republic of Vietnam was proclaimed on September 2, 1945: a government for the entire country, replacing the Nguyễn dynasty. Hồ Chí Minh became leader of the Democratic Republic of Vietnam.
