Alfonso II of Aragon

Alfonso II (1–25 March 1157 – 25 April 1196), called the Chaste or the Troubadour, was the King of Aragon and, as Alfons I, the Count of Barcelona from 1164 until his death. The eldest son of Count Ramon Berenguer IV of Barcelona and Queen Petronilla of Aragon, he was the first King of Aragon who was also Count of Barcelona. He was also Count of Provence, which he conquered from Douce II, from 1166 until 1173, when he ceded it to his brother, Ramon Berenguer III. 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. Reign Born at Huesca, Alfonso, called indistinctly from birth Alfonso and Ramon, ascended the united throne of Aragon and Barcelona as Alfonso, in deference to the Aragonese, to honour Alfonso the Battler. For most of his reign he was allied with Alfonso VIII of Castile, both against Navarre and against the Moorish taifas of the south. In his Reconquista effort Alfonso pushed as far as Teruel, conquering this important stronghold on the road to Valencia in 1171. The same year saw him capturing Caspe. Apart from common interests, kings of Aragon and Castile were united by a formal bond of vassalage the former owed to the latter. Besides, on January 18, 1174, in Zaragoza Alfonso married Sancha, sister of the Castilian king. Another milestone in this alliance was the Treaty of Cazorla between the two kings in 1179, delineating zones of conquest in the south along the watershed of the rivers Júcar and Segura. Southern areas of Valencia including Denia were thus secured to Aragon. Alfonso also reached an agreement, the Treaty of Sangüesa (1168), with Sancho VI of Navarre dividing the territory of the Taifa of Murcia between them.
