High Quality Content by WIKIPEDIA articles! Alfonso II (Aragon) or Alfons I (Provence and Barcelona; 1157 25 April 1196), called the Chaste or the Troubadour, was the King of Aragon and Count of Barcelona from 1162 until his death. He was the son of Ramon Berenguer IV of Barcelona and Petronilla of Aragon and the first King of Aragon who was also Count of Barcelona. He is thus sometimes called, like his successors, especially by Catalan historians, the "count-king". He was also Count of Provence from 1167, which he acquired from the heiress Douce II, until 1173, when he ceded it to his brother Berenguer. His reign has been characterised by nationalistic and nostalgic Catalan historians, as l'engrandiment occitànic or "the Pyrenean unity": a great scheme to unite various lands on both sides of the Pyrenees under the rule of the House of Barcelona.
