Guanarteme Tenesor Semidán

Tenesor Semidán was 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. He spent time at the court of the Catholic Monarchs and returned 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. Chronicle tradition describes that intervention as mediation, though no complete account of its details survives.

The descent and several family identifications associated with Fernando Guanarteme are historiographically problematic, and his birth and death dates are not known with certainty. His figure stands as a point of contact between colonial documentation, conquest chronicles and later Indigenous memory.
