The Xinhai Revolution (or the Hsin-hai Revolution), also known as the Revolution of 1911, or the Chinese Revolution, was a revolution that overthrew China's last imperial dynasty (the Qing dynasty), and established the Republic of China (ROC). The revolution was named Xinhai (Hsin-hai) because it occurred in 1911, the year of the Xinhai (辛亥) stem-branch in the sexagenary cycle of the Chinese calendar.
