The Battle of Gáldar, fought in 1483, marked the end of the indigenous resistance in Gran Canaria during the Castilian conquest period. This decisive confrontation occurred in the context of the Crown of Castile's expansion into the Canary Islands, a process that began in the 15th century. The indigenous resistance, led by the guanarteme Tenesor Semidán, was ultimately subdued after intense fighting. The Castilian victory consolidated control over Gran Canaria, facilitating the island's subsequent integration into the Kingdom of Castile. This event had profound repercussions, not only on the island's political and social structure but also on its demography, due to the decline of the indigenous population and the arrival of European settlers. The Battle of Gáldar symbolizes the end of an era and the beginning of a new chapter in the history of the Canary Islands.
