Margarita Fernández Guanarteme, also known by her native name Guayarmina (1470-1550), was a Guanche princess, whose family ruled during the time of the conquest of the Canary Islands at the end of the 15th century.

[1] The philologist Ignacio Reyes translated her native name to signify a "guard, reserve or protection until a prolonged drought", while adding that it also referred figuratively to the star Canopus.

[5] After the capture of Tenesor Semidán by Alonso Fernández de Lugo and Hernán Peraza in 1482, the Guanches moved Guayarmina and her cousin Masequera, daughter of the former king Egonaiga el Bueno and the true holder of power on the island, to the natural fortresses in the interior of the island.

[6] After several clashes in the fortresses of Bentayga, Ajódar and others, the Castilian conquerors under the command of Pedro de Vera, accompanied by Tenesor Semidan - now called Fernando Guanarteme - besieged the natives at Ansite.

[7] After the definitive incorporation of the island into the Crown of Castile, Guayarmina was Christianised and baptised as Margarita Fernández Guanarteme, and settled in the town of Gáldar.
