Guanarteme Tenesor Semidán

Tenesor Semidán is presented by historiography as the guanarteme of Gáldar, one of the main political spheres of Indigenous Gran Canaria. After his capture during the final phase of the conquest, he was baptised as Fernando Guanarteme. Chronicles and later studies place him at the court of the Catholic Monarchs and on his return to the islands as an intermediary between Castilians and the Canarian population.

His most frequently cited role is linked to Ansite, the episode that preceded the end of Gran Canaria's conquest in 1483. That intervention is best described as mediation attributed by chronicle tradition, not as a separate battle or as a conflict-free surrender documented in every detail.

The descent and several family identifications associated with Fernando Guanarteme are historiographically problematic. He is best treated as a point of contact between colonial documentation, conquest chronicles and later Indigenous memory.
