Sonam Drakpa deposes Drakpa Changchub as ruler of Tibet.
The Ming dynasty of China annexes the areas of the old Kingdom of Dali, in modern-day Yunnan and Guizhou provinces, inhabited by the Miao and Yao peoples. Hundreds of thousands of Chinese (including military colonists) will migrate there from the rest of China.
In Ming dynasty China, the lijia census registration system begun in 1371 is now universally imposed, during the reign of the Hongwu Emperor. The census counts 59,873,305 people living in China in this year. This depicts a drastic drop in population since the Song dynasty, which counted 100 million people at its height in the early 12th century. A modern historian states that the Ming census is inaccurate, as China at around this time has at least 65,000,000 inhabitants, if not 75,000,000.[1]
