In season 74/75 the newly named club won their first trophy when after beating Realmont XIII 9-8 in the National League 1 they were promoted to the top flight.

A change of colours to the cities blue and white didn't bring with it any good luck as a major sponsor pulled out of the club in 1992 leaving them in severe financial trouble, relegation to the bottom tier soon followed.

In 2004 it was announced that AS Cadurcienne and Villefranche de Rouerge XIII would join forces to become Union Villefranche-Cahors abbreviated to UVC and that they compete in the top tier Elite One Championship.

In 2007 the partnership was ended and Cahors Lot XIII were born and began life in the bottom tier National Division 2.

In season 2012/13 they reached the Midi-Pyrenees regional final against Gratentour XIII[1] The Stade Lucien Desprats has been used by the club since 1946, prior to this they played at the Gambetta High School.
