Jules Ferry in the context of Sino-French War

The Moderates or Moderate Republicans (French: Républicains modérés), pejoratively labeled Opportunist Republicans (Républicains opportunistes), was a French political group active in the late 19th century during the Third French Republic. The leaders of the group included Adolphe Thiers, Jules Ferry, Jules Grévy, Henri Wallon and René Waldeck-Rousseau.

Although described as centre-left and considered leftist at the time, the Moderate Republicans were ideologically a centre-right political party.

The Retreat from Lạng Sơn (French: retraite de Lang-Son) was a controversial French strategic withdrawal in Tonkin at the end of March 1885 during the Sino-French War (August 1884 to April 1885). It represented the last major event of the conflict and was deemed a considerable embarrassment in France, further cementing negative public opinion about the colonial conflict which led to the collapse of French Prime Minister Jules Ferry's government.

The Battle of Thuận An (20 August 1883) was a clash between France and Vietnam during the period of early hostilities of the Tonkin Campaign (1883–1886). During the battle a French landing force under the command of Admiral Amédée Courbet stormed the coastal forts that guarded the river approaches to the Vietnamese capital Huế, enabling the French to dictate a treaty to the Vietnamese that recognised a French protectorate over Tonkin. The French strike against the Vietnamese in August 1883, sanctioned by Jules Ferry's administration in Paris, did more than anything else to make a war between France and China inevitable, and sowed the seeds of the Vietnamese Cần Vương national uprising in July 1885.
