Phú Xuân

[1] In 1306, the King of Champa Chế Mân offered Vietnam two Chăm prefectures, Ô and Lý, in exchange for marriage with a Vietnamese princess named Huyền Trân.

Kim's eldest son, Nguyễn Uông, was also assassinated in order to secure Trịnh Kiểm's authority.

The Nguyễn lords chose Thừa Thiên, a northern territory of Thuận Hóa, as their family seat.

[10] However, Tây Sơn rebellions broke out in 1771 and quickly occupied a large area from Quy Nhơn to Bình Thuận, thereby weakening the authority and power of the Nguyễn lords.

[14] Under the reign of emperor Quang Trung, Phú Xuân became Tây Sơn dynasty capital.
