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 early days of the Third Republic were dominated by political disruptions caused by the Franco-Prussian War of 1870–1871, which the Republic continued to wage after the fall of Emperor Napoleon III in 1870. Harsh reparations exacted by the Prussians after the war resulted in the loss of the French regions of Alsace (keeping the Territoire de Belfort) and Lorraine (the northeastern part, i.e. present-day department of Moselle), social upheaval, and the establishment of the Paris Commune. The early governments of the Third Republic considered re-establishing the monarchy, but disagreement as to the nature of that monarchy and the rightful occupant of the throne could not be resolved. Consequently, the Third Republic, originally envisioned as a provisional government, instead became the permanent form of government of France.
