Hanoi (Vietnamese: Hà Nội, listen), is the capital of Vietnam and the country's second largest city. Its population in 2009 was estimated at 2.6 million for urban districts,[1] 6.5 million for the metropolitan jurisdiction.[2] From 1010 until 1802, it was the most important political centre of Vietnam. It was eclipsed by Huế during the Nguyen dynasty as the capital of Vietnam, but Hanoi served as the capital of French Indochina from 1902 to 1954. From 1954 to 1976, it was the capital of North Vietnam.

The city is located on the right bank of the Red River. Hanoi is located at 1,760 km (1,090 mi) north of Ho Chi Minh City.

October 2010 officially marked 1000 years since the establishment of the city. On this occasion, Hanoi was named by Frommer's travel guide as one of the world's "Top Destinations 2010".[3]
