Its two other chief towns were Figeac and Moissac. Ecclesiastically it was included almost entirely in the diocese of Cahors until 1317, when a bishopric for lower Quercy was established at Montauban.

The demand was absurd and exorbitant and was refused, though the French government offered him the hand of their kings daughter Catherine with a dowry of 800,000 crowns and the districts of Quercy and Prigordsufficiently handsome terms. When he began to collect a fleet and an army, they added to the offer the Limousin and other regions; but Henry was determined to pick his quarrel, and declared war in an impudent and hypocritical manifesto, in which he declared that he was driven into strife against his will.
During the wars between England and France in the reign of Henry II., the English placed garrisons in the county, and by the treaty of Paris in 1259 lower Quercy was ceded to England.
