Borja, Zaragoza in the context of "Mudéjar"

Alfonso I (c. 1073/1074 – 7 September 1134), called the Battler or the Warrior (Spanish: el Batallador), was King of Aragon and Navarre from 1104 until his death in 1134. He was the second son of King Sancho Ramírez and successor of his brother Peter I. With his marriage to Urraca, queen regnant of Castile, León and Galicia, in 1109, he began to use, with some justification, the grandiose title Emperor of Spain, formerly employed by his father-in-law, Alfonso VI. Alfonso the Battler earned his sobriquet in the Reconquista. He won his greatest military successes in the middle Ebro, where he conquered Zaragoza in 1118 and later took Ejea, Tudela, Calatayud, Borja, Tarazona, Daroca, and Monreal del Campo. He died in September 1134 after an unsuccessful battle with the Muslims at the Battle of Fraga.

Alfonso's nickname comes from the Aragonese version of the Chronicle of San Juan de la Peña (c. 1370), which says that "they called him lord Alfonso the battler because in Spain there wasn't as good a knight who won twenty-nine battles" (clamabanlo don Alfonso batallador porque en Espayna no ovo tan buen cavallero que veynte nueve batallas vençió).

The House of Borgia (/ˈbɔːr(d)ʒə/ BOR-zhə, BOR-jə; Italian: [ˈbɔrdʒa]; Spanish and Aragonese: Borja [ˈboɾxa]; Valencian: Borja [ˈbɔɾdʒa]) was a noble family of Spanish origins, which rose to prominence during the Italian Renaissance. They were from Xàtiva, Kingdom of Valencia, the surname being a toponymic from the town of Borja, then in the Crown of Aragon, in Spain.

The Borgias became prominent in ecclesiastical and political affairs in the 15th and 16th centuries, producing two popes: Alfons de Borja, who ruled as Pope Callixtus III during 1455–1458, and his nephew Rodrigo Lanzol Borgia, as Pope Alexander VI, during 1492–1503.
