Hanoi is located in Vietnam and was originally named Da Luo City. Hanoi is very important to Vietnam, but for a period of time in history, Hanoi was a Chinese city, originally named Luo City or Da Luo City. How did this ancient city become the capital of Vietnam? During the Five Dynasties and Ten Kingdoms period, the world was in chaos and Vietnam became independent. The roads in early Vietnam after independence were still centered on Da Luo City.
In the 11th century, Li Gongyun, the founder of the Vietnamese Li Dynasty, believed that Da Luo City was located in the center of heaven and earth, rich in resources and large in population, and was an ideal place to implement the rule of Dai Viet, so he considered moving the capital to Da Luo City. But Da Luo City is a Chinese name, so Li Gongyun gave it a new name, called Thang Long. Since then, Vietnam has expanded southward with Thang Long as the center, extending southward to the Mekong River Basin. Hanoi has been the capital of many dynasties in Vietnamese history, including the Le Dynasty. The Ming Dynasty took back Hanoi and made it the capital of the newly established Jiaozhi Province. The Ming Dynasty called Jiaozhou Prefecture. After the Ming Dynasty moved the capital, it became the capital of the Later Le Dynasty and was renamed Tokyo.
In 1831, Hanoi was named after the Nguyen Dynasty and has been used ever since. During the Nguyen Dynasty, the capital of Vietnam was Hue. After the French occupation of Vietnam, Hanoi became the seat of the French Governor-General and the actual ruling center of Vietnam. After World War II, Vietnam fell into division and Hanoi became the capital of North Vietnam. In 1976, Vietnam was unified and Hanoi was designated as the capital of the soon-to-be unified Vietnam.
