Fontenay was in existence as early as the time of the Gauls. The affix of comte is said to have been applied to it when it was taken by King Louis IX from the family of Lusignan and given to his brother Alphonse, count of Poitou, under whom it became capital of Bas-Poitou. Ceded to the Plantagenets by the Treaty of Brétigny, in 1360 it was retaken in 1372 by Duguesclin. It suffered repeated capture during the Religious Wars of the 16th century, was dismantled in 1621 and was occupied both by the Republicans and the Royalist Vendeans during the Revolt in the Vendée (1793). From 1790 to 1806 it was capital of the Vendée department.
At Maison Laval on rue Rabelais, a townhouse built at the end of the 18th Century, Emperor Napoleon 1st and his wife, Joséphine, spent the night of August 7 and 8, 1808. On their way from Rochefort to Nantes, they had stopped off in the Bas-Poitou capital of Fontenay-le-Comte where they were the guests of Mayor Laval who, to give them a dignified welcome, had prepared a triumphal arch over the Pont Neuf bridge. That night, the Emperor learned of the defeat of General Dupont at Bailem. The General's surrender, which seriously compromised the French army's position in Spain, threw the Emperor into a deep rage. If word is to be believed, the Emperor smashed an earthenware vase placed in front of him.
- François Rabelais (1493–1553) was a monk at Fontenay-le-Comte, where he studied Greek and Latin, as well as science, philology, and law.
- Georges Simenon(1903 – 1989) the Belgian writer, author of the Maigret series and other books, stayed at the Chateau de Terreneuve during the war. Several stories are based in the Vendee and at least one in Fontenay. There is a Simenon tour.
