The French Third Republic (French: Troisième République, sometimes written as La IIIe République) was the system of government adopted in France from 4 September 1870, when the Second French Empire collapsed during the Franco-Prussian War, until 10 July 1940, after the Fall of France during World War II led to the formation of the Vichy government. The French Third Republic was a parliamentary republic.
The early days of the French Third Republic were dominated by political disruption caused by the Franco-Prussian War of 1870–1871, which the Third Republic continued to wage after the fall of Emperor Napoleon III in 1870. Social upheaval and the Paris Commune preceded the final defeat.
