In 1458 Alfons V, the king of Aragon, tried to keep peace with Castile. He was succeeded by his brother Johan II of Aragón. Johan was less focused on reconciliation. When in 1460 Castilean nobles decided to conspire against the King of Castile, Hendrik IV, the new king of Aragon supported this covenant against Hendrik. The covenant

The covenant took part, Johan II of Aragón, Admiral Fadrique Enríquez de Mendoza, and Brother Enrique, Pedro Manrique de Lara, Alfonso Carrillo, Archbishop of Toledo, Pedro Girón, Commander of the Order of Calatrava, Juan Pacheco and Archbishop from Sevilla, Alonso I de Fonseca. Juan Pacheco played a role as a double pony. Pacheco convinced Alonso de Fonseca to leave the League and choose Hendrik's side.
