What factors weakened the Ming dynasty before its fall in 1644?

The decline and eventual fall of the Ming dynasty in 1644 were driven by a combination of internal political decay, economic strain, and external military threats.1

Political and Bureaucratic Decay

The dynasty suffered from a long-term decline in administrative discipline. Weak emperors frequently withdrew from governance, allowing powerful eunuchs to dominate the court and purge reform-minded officials, such as those associated with the Donglin party. This led to vicious partisan wrangling that paralyzed the bureaucracy and demoralized the government, leaving the state unable to respond effectively to crises.1

Economic and Social Instability

The government faced significant financial pressure, exacerbated by the costs of military campaigns, such as the prolonged war in Korea. Oppressive taxation and conscription, coupled with natural disasters like the great famine of 1630, fueled widespread unrest. These conditions fostered internal rebellions, most notably led by Li Zicheng, whose forces eventually captured Beijing.12

External Threats

Simultaneously, the Manchu people, led by Nurhachi, steadily encroached on the northern frontier. Following decisive military victories, the Manchu seized control of the northeast, forcing the Ming to fight a two-front struggle against internal rebels and external invaders. The dynasty ultimately collapsed when the capital fell to Li Zicheng and the subsequent Manchu intervention.12
