Anti-French sentiment (Francophobia) refers to a dislike or hatred toward France, the French people, the French government or the Francophonie (set of political entities that use French as an official language or whose French-speaking population is numerically or proportionally large). It has existed in various forms and in different countries for centuries. Its antonym is Francophilia.
Though French history in the broadest sense extends back more than a millennium, its political unity dates back from the reign of Louis XI, who set up the basis of nation-state (rather than a dynastic, transnational entity typical of the late Middle Ages). According to Eric Hobsbawm (1990), only aristocrats and scholars spoke French before the French Revolution. About two-thirds of the population of the French kingdom spoke a variety of local indigenous languages l, often referred to as dialects. Henceforth, Hobsbawm argues that the French nation-state was constituted during the 19th century through conscription, which accounted for interactions between French citizens coming from various regions and the Third Republic's public instruction laws, enacted in the 1880s, probably in parallel with the birth of the European nationalisms.
England and France have a long history of conflict, dating from before the Battle of Hastings, when William the Conqueror claimed the English throne. Before becoming King of England, William found conflict with his liege several times and conquered some neighbouring fiefs. The relationship between the countries continued to be filled with conflict, even during the Third Crusade. The medieval era of conflict climaxed during the Hundred Years' War, when the House of Plantagenet fought unsuccessfully for control of the French throne and lost almost all French holdings, which resulted in future English kings being more culturally English. (Previously, they had largely spoken French and lived in French castles much of the time. Richard the Lionheart, who was famous for his feud with French King Philip, spent most of his life in France and as little as six months of his reign as King in England).
