Ming’s cold decades: famine, a northern invasion & the fall of Beijing

People & leaders: Zhu Yuanzhang / Hongwu Emperor (1328–1398); Wanli Emperor (1563–1620); Chongzhen Emperor (1611–1644); Li Zicheng (1606–1645); Nurhaci (1559–1626); Dorgon (1612–1650)

The Ming dynasty’s last decades show why drought and cold must be studied alongside taxation, military organization and contested legitimacy. The weather became harder; the political system failed to protect many of the people living through it.

The foundation was a durable recovery, not an eternal settlement

Zhu Yuanzhang founded the Ming in 1368 after years of rebellion and war. He rebuilt imperial administration and sought to restore agricultural production, registration and tax collection. Later rulers invested in canals, frontier defenses and the capital at Beijing. This was a major institutional achievement. Yet the supply of northern armies depended on grain moving from other regions, and changing prices or damaged waterways could create military as well as civilian shortages.

Despite a strong central court, the dynasty never controlled the weather. Historians reconstruct cold spells, droughts and floods from regional gazetteers, price data and other documents. A single national average conceals differences between the north, the Yangtze basin and northeast Asia.

The long deterioration of the late sixteenth and seventeenth centuries

Climate historian Timothy Brook identifies repeated cold and dry conditions after the late sixteenth century, with severe drought in parts of the north between 1637 and 1643. Tree-ring research published in 2024 identifies protracted northern megadroughts in 1576–1593 and 1628–1644. Research on contrasting conditions in North and Northeast China suggests that these shocks affected the competing Ming and rising Manchu states differently.

Harvest failures meant not only empty granaries but also reduced tax payments, grain-price spikes and refugees unable to remain on their farms. Army units could go unpaid or undersupplied; officials argued about how to meet urgent expenses. Climate contributed to the crisis without creating the political structure that made suffering worse. War, administrative weakness, factional conflict and fiscal strain remained essential parts of the explanation.

How Beijing was lost in 1644

Li Zicheng’s rebel forces gained ground in an exhausted northern countryside. In April 1644 they entered Beijing; the Chongzhen emperor died as Ming authority in the capital collapsed. A Ming general, Wu Sangui, later cooperated with Manchu forces approaching through Shanhai Pass. Manchu armies entered Beijing and established Qing rule, although fighting to consolidate the conquest continued for decades.

The outcome was not decided by drought alone, and it was not a single pitched battle. Rebel organization, troop morale, frontier alliances, fiscal crisis and political mistakes all mattered. Ming rulers had presided over lasting cultural and administrative achievements. Their defeat exposed the fragility of a government that could no longer keep soldiers paid, grain available and elites united when exceptional environmental stress arrived.
