Northern Vietnam
Northern Vietnam (Vietnamese: Bắc Bộ) is one of three geographical regions in Vietnam. It consists of three sub-regions: the Northwest (vùng Tây Bắc), the Northeast (vùng Đông Bắc), and the Red River Delta (Đồng bằng sông Hồng). Unlike tropical Southern Vietnam, Northern Vietnam has a subtropical climate.
The region was historically referred to by various names in Vietnamese: Bắc Kỳ during the Nguyễn dynasty, Bắc Bộ from 1945 to the present (encompassing the Empire of Vietnam and the Democratic Republic of Vietnam), and Bắc Phần, sometimes Bắc Việt, during the State of Vietnam.
It has a total area of about 109,942.9 km2. The region's largest city, Hanoi, serves as the country's capital. Among the three geographical regions, the oldest is Northern Vietnam. Vietnamese culture originated in the Red River Delta and the Kinh Vietnamese eventually spread south into the Mekong Delta.
