In the 19th century, the great Chinese Diaspora began. Losses due to emigration were added to by conflicts and catastrophes such as the Northern Chinese Famine of 1876–79, in which between 9 and 13 million people died. In 1898, the Guangxu Emperor drafted a reform plan to establish a modern constitutional monarchy, but these plans were thwarted by the Empress Dowager Cixi. The ill-fated anti-Western Boxer Rebellion of 1899–1901 further weakened the dynasty. Although Cixi sponsored an ambitious program of reforms, the Xinhai Revolution of 1911–12 brought an end to the Qing dynasty and established the Republic of China.
