The Reconquista and Negotiations with Granada

Timeline

1. 1290Granada–Castile border · AndalusiaGranada's Sultan Muhammad II, Sancho IV, and the ruler of Tlemcen reached a tripartite arrangement: Castile would attack Tarifa, still held by the Marinids; Granada would attack other Marinid strongholds; and Tlemcen in North Africa would launch a diversionary campaign against the Marinids. The agreement stipulated that once Castile took Tarifa, it would hand it over to Granada in exchange for six border fortresses.
2. 1291–1292Tarifa · AndalusiaAfter meeting with Sancho IV in 1291, James II of Aragon joined the war against the Marinids. In October 1292, with Aragonese naval and Granadan logistical support, Castile captured Tarifa and received the six fortresses, but after meeting Muhammad II in Córdoba, Sancho IV refused to hand over Tarifa. Granada then allied with the Marinids, and their joint siege of Tarifa in 1294 failed.
