The Sino-French War, Tonkin War, or Tonquin war, was a conflict between China and France regarding the control of Tonkin, a region in northern Vietnam. The Qing Dynasty performed well on land and won limited strategic victories; however, the Qing forces in Taiwan and other surrounding islands were defeated by the French. Ultimately, the war ended with the Treaty of Tientsin, which arguably satisfied most of the goals of the French.
1894 · First Sino-Japanese War
The First Sino-Japanese War was a conflict regarding Korean influence between Japan and China. The fighting began on July 25, 1894, and ended on April 17, 1895. This period was notable for Japan beginning to show regional dominance over China, primarily due to the fact that the Qing Dynasty's military had not been sufficiently modernized. In February of 1895, after suffering repeat losses for over six months, the Qing Dynasty sued for peace, initiating the close of the war.
1898 · French Territory
The region was still a small fishing port when it was occupied by the French in 1898. The next year, the French forced the Chinese to lease a small enclave of Zhanjiang to them for 99 years as the territory of Kouang-Tchéou-Wan. The French wanted to develop the port, which they called Fort-Bayard.
