Sancho III of Navarre in the context of Queen of Aragon

This is a list of the kings and queens of Aragon. The Kingdom of Aragon was created sometime between 950 and 1035 when the County of Aragon, which had been acquired by the Kingdom of Navarre in the tenth century, was separated from Navarre in accordance with the will of King Sancho III (1004–35). In 1164, the marriage of the Aragonese princess Petronila (Kingdom of Aragon) and the Catalan count Ramon Berenguer IV (County of Barcelona) created a dynastic union from which what modern historians call the Crown of Aragon was born. In the thirteenth century the kingdoms of Valencia, Majorca and Sicily were added to the Crown, and in the fourteenth the Kingdom of Sardinia and Corsica. The Crown of Aragon continued to exist until 1713 when its separate constitutional systems (Catalan Constitutions, Aragon Fueros, and Furs of Valencia) were abolished by the Nueva Planta decrees at the end of the War of the Spanish Succession.
