Answer:
By the 1900s the Qing were growing very corrupt, and many communists, republicans, liberals, and anarchists worked together to overthrow the dynasty once and for all. By this time, the emperor, or empress, Dowager Cixi, died. She was succeeded by a 2 year old boy, and many thought it was absurd for a 2 year old to rule over a massive country. This made a perfect time to overthrow the Qing. In 1911, they staged a revolution, similar to Russia's Feburary revolution.
