Second Era of Northern Domination

The Second Era of Northern Domination refers to the second period of Chinese rule in Vietnamese history, from the 1st century to 6th century AD, during which present-day northern Vietnam (Jiaozhi) was governed by various Chinese dynasties. This period began when the Han dynasty reconquered Giao Chỉ (Jiaozhi) from the Trưng Sisters and ended in 544 AD when Lý Bí revolted against the Liang dynasty and established the Early Lý dynasty.
