Historical Evolution
Hanoi's history is a tapestry of resilience and transformation. From the early settlements of Cổ Loa and the period of Nanyue to centuries of Chinese rule, the city has evolved through various names, including Thăng Long, Đông Đô, Đông Quan, and Đông Kinh.
The city underwent a significant shift during the French colonial era, beginning with the occupation on November 20, 1873. This period left a lasting architectural mark on the city, which remained under colonial influence until liberation on October 10, 1954. Following the First Indochina War and the Vietnam War, Hanoi emerged as the central hub of a reunified Vietnam.
