In what year did France become the third republic?

The main reason for the emergence of a new republic was that France in those years was waging a difficult war with Prussia. On September 1, 1870, the main battle of the Franco-Prussian War took place, where the first suffered a crushing defeat. Already on the 4th, the crowd broke into the Bourbon Palace and demanded the proclamation of a republic. Thus, on September 4, 1870, the III Republic was proclaimed in France. It lasted until the outbreak of hostilities in World War II, and was eliminated on July 10, 1940. When the fascist troops occupied France and established their own order there, the third republic was replaced by the Vichy regime.
