Answer:
The Wuchang Uprising on 10 October 1911 led to the Xinhai Revolution. The abdication of Puyi, the last emperor, on 12 February 1912, brought the dynasty to an end.
Step-by-step explanation:
Two of the most tragic events were the Sino-Japanese War of 1894 and the foreign invasion of 1900 after the Boxer Rebellion. Defeated in the Sino-Japanese War, Qing gave up Korea, a country formerly paying tribute to Qing Dynasty, and Taiwan, a part of its territory.
Good luck!
