The prodigious growth of the fortified town of Mons Albanus or Mont Alban, allows the new town of Montauban to shine on the flat country where the Tarn and Aveyron rivers converge. At the expense of Moissac Abbey, the austere cahorsin Jacques Duez, Pope under the name John XXII, seals the domination by creating the diocese of Montauban in 1317. Following the breakup of the County of Rodez in 1486, Caussade became the capital of a fortified barony. The last count of Rodez, Charles d'Armagnac, had been in favour of his illegitimate son Pierre taking the lordship. In 1562, the barony fell to Cardinal Georges d'Armagnac. In retaliation, the town was sacked by the Huguenot Duras. Georges d' Armagnac sold it in 1583 to Jacques Villeneuve, prior of the bream in Toulouse.

Besieged, the small Calvinist fortress went to the troops of Louis XIII during the first campaign in 1621. Caussade depended on the election and stewardship of Montauban and the parliament of Toulouse. Contrasting with the slow erasure of Haut-Quercy, the last two centuries of the Ancien Régime are the economic heyday of this prosperous southern area, diversified agriculture, viticulture and arboriculture refined the remarkable industrial dynamics, driven by textile and mills. In the seventeenth and eighteenth century, Bordeaux's proximity began to touch the valleys of the Quercy. Old polyculture here and there supplemented by dyeing and textile crops, declines. Industrial crops regress in 1830, apart from tobacco . After 1850, fruit and vegetable crops characterise the country of the Garonne. Until 1900, rail encouraged the production and export of tomatoes, peas, beans, onions, asparagus and cauliflower plus artichokes and melons in a few areas. After the crises of the vine by phylloxera between 1880 and 1900, fruit crops were grown, especially plums, cherries and table grapes. Economic change in industrial France after 1850 dramatically increased emigration to attractive areas or major cities and the northern areas, causing an exodus compounded by the population decline of the world wars. Caussade, did not avoid the demographic decline . The Straw Hat industry was born from a cottage industry, using "pailloles" braided by shepherdesses of sheep as straw
