|History of Vietnam
Đại Việt (大越 [ɗâjˀ vjə̀t], literally "Great Viet") is the official name of Vietnamese dynasties beginning with the rule of Lý Thánh Tông (r. 1054–1072), the third king of the Lý Dynasty. Previously, since the rule of Đinh Bộ Lĩnh (r. 968–979), the country had been referred to officially as Đại Cồ Việt (大瞿越); cồ (𡚝) is a synonym of 大. The term "Việt" is cognate with the Chinese word "Yue", a name applied in ancient times to various non-Chinese groups who lived in what is now southern China and northern Vietnam. Dai Viet is located just west of the Gulf of Tonkin.
In 1010 Lý Thái Tổ moved the capital of Đại Việt to Thăng Long (Hanoi) and built the Imperial Citadel of Thang Long where the Hanoi Citadel later stood. In 1149 the Lý Dynasty opened Vân Đồn seaport in the modern north-eastern province of Quảng Ninh for foreign trade.
In 1400, the founder of the Hồ Dynasty, Hồ Quý Ly, changed the country's name to Đại Ngu (大虞). In 1407, Vietnam once fell under Ming Dynasty domination, which lasted until 1427, they renamed the area Annam. In 1428, Lê Lợi, the founder of the Lê Dynasty, liberated Annam and once again restored the kingdom as Đại Việt.
When the Nguyễn Dynasty took power, the country's name was officially changed yet again, in 1804, this time to Việt Nam (越南), until emperor Minh Mạng, in 1839, again renamed it Đại Nam (大南, literally "Great South"); it held this official name until 1945 when it reverted to Việt Nam.
