Kings of Aragon

Charlemagne conquered Barcelona from the Moors 801. He created the "Spanish March", which was divided into several counties who were subordinated to the count of Barcelona. This count usually controlled more than one county and with time became Barcelona more and more independent until 987 when they refused to recognise the French king's supremacy. France would however not recognise Barcelona's independence until the treaty of Corbeil 1258. But by then hade the county of Barcelona become an important regional power with greatly expanded dominions. The most important of these were Aragon, which became the name of the united crown as it was a kingdom and Barcelona just a county.

The Kingdom of Aragon had been created when Sancho III of Navarre partitioned his kingdom between his three sons 1035. In the beginning was Aragon just an insignificant mountain kingdom, but it expanded considerably during the Reconquista. Queen Petronilla married the count of Barcelona, Ramón Berenguer IV, and their mutual son took over both states when the father died 1162. During the reconquista, Jaime I conquered Mallorca and Valencia from the Moors 1229 and 1238 respectively. These lands were called kingdoms although they were permanently united with Aragon. The crown of Aragon was it self united with crown of Castile 1479 when Fernando the Catholic became king. He had already been regent of Castile as husband to queen Isabel. This union meant that the kingdom of Spain was created.
