House of Trastámara
This Lordship was created in 1418 by King Alfonso V of Aragon, called "the Magnanimous", for his brother John II, symbolically linked to the city that had been capital of the suppressed County of Urgell, the feudal command of the greater rival of the House of Trastámara for the possession of the Aragonese Crown during the Interregnum, James II, Count of Urgell.
