in the ninth century and inherited by scions of the ducal house in the tenth. It remained semi-independent of ducal authority throughout the next two centuries, and was briefly attached to the Viscounty of Béarn (1080–1097). Thereafter the Counts of Bigorre, notable participants in the Reconquista, the Crusades, and the war against the Cathars, strongly asserted their independence, though on a few occasions they prudently acknowledged the suzerainty of another; as of Alfonso II of Aragon in 1187. Confiscated in 1292 by King Philip IV of France who intervened in a quarrel over the succession of Bigorre, the area was surrendered to Edward III of England by virtue of the Treaty of Brétigny (1360), which marked the end of the first phase of the Hundred Years' War. Recaptured by the French and their allies the counts of Foix between 1370 and 1406, Bigorre was granted by King Charles VII of France to Count Jean I of Foix in 1426. Thus, Bigorre was incorporated into the estates of the House of Foix-Grailly, which included the county of Foix, Béarn, and Nébouzan. Later, the estates of the House of Foix-Béarn passed through heiresses to the House of Albret, then eventually to the House of Bourbon with Henry III of Navarre, son of Antoine de Bourbon and Jeanne d'Albret. Henry III of Navarre became King Henry IV of France in 1589. In 1607, he united to the French crown those of his personal fiefs that were under French sovereignty (i.e. County of Foix, Bigorre, Quatre-Vallées, and Nébouzan, but not Béarn and Lower Navarre, which were sovereign countries outside of the kingdom of France), and so Bigorre became part of the royal domain. Before the French Revolution, Bigorre was made part of the gouvernement (military area) of Guienne-Gascony, whereas for general matters it depended from the généralité of Auch like the rest of Gascony (although for a certain period of time it depended from the généralité of Pau, like Béarn, Nébouzan, County of Foix, and the Basque provinces). For judicial matters, Bigorre depended from the Parlement of Toulouse. Unlike so many other French provinces, Bigorre kept its provincial parliament, its estates, until the Revolution. The provincial estates of Bigorre decided the level of taxation in Bigorre, and how much tax money was given to the king of France. In 1789 Bigorre sent four representatives to the Estates-General in Versailles. The representatives of Bigorre lobbied
