The title was disputed by Peter I and Guerau IV de Cabrera during Aurembiaix's time.

After a period of dynastic squabbles Jaume I acknowledged Ponç IV of Cabrera as the successor to the County of Urgell.

The bishop of Urgell, who since 2003 has been Joan Enric Vives Sicília, is simultaneously joint head of state of Andorra alongside the President of the French Republic.
