Early Victories and Expansion

Consolidation of Power
- In 1776, Nguyễn Nhạc declares himself king (Tây Sơn Vương), marking a pivotal moment in consolidating power against Nguyễn forces.

- In May 1785, a decisive battle occurs at Mỹ Tho where Nguyễn Huệ defeats Siamese forces within one day.
Northern Campaign Against Trịnh Lords

Nguyễn Huệ's Rise to Power and the Fall of the Tây Sơn Dynasty
Nguyễn Nhạc Transfers Power
- Nguyễn Nhạc, recognizing his limitations, transfers supreme power to his brother, Nguyễn Huệ. This decision is pivotal as it sets the stage for significant military actions against external threats.
Military Preparations and Initial Successes
- Nguyễn Huệ prepares his troops in Thuận Hóa, aiming to confront the larger threat from the North. He confidently predicts a swift victory over the Qing forces within ten days.

- After securing victory, Nguyễn Huệ returns to Phú Xuân to consolidate power and strategize against Nguyễn Ánh.
Decline of the Tây Sơn Dynasty
- On September 16, 1792, Emperor Quang Trung dies unexpectedly. His son, Nguyễn Quang Toàn, ascends but lacks leadership capabilities due to his young age.
- The absence of strong leadership leads to rapid decline for the Tây Sơn dynasty as Nguyễn Ánh seizes this opportunity to launch attacks against them.
Final Confrontation and End of an Era
- By 1800, Nguyễn Ánh successfully captures Thăng Long. Quang Toàn attempts resistance but ultimately fails and is captured and executed.
- This marks a definitive end for the Tây Sơn dynasty amidst ongoing conflicts in Vietnam's history.
