During the Spanish Conquest of the Canary Islands the island of La Gomera was not taken in battle but was incorporated into the Peraza-Herrera fiefdom through an agreement between Hernán Peraza the Elder and some of the insular aboriginal groups who accepted the rule of the Castilian. However, there were a number of uprisings by the Guanches aboriginals due to outrages committed by the rulers on the native Gomeros. The last of these, in 1488, resulted in the death of his son and Beatriz's husband, Hernán Peraza the Younger. Beatriz de Bobadilla y Ossorio then had to seek the assistance of Pedro de Vera, conqueror of Gran Canaria, in order to snuff out the rebellion. The subsequent repression caused the death of two hundred rebels and many others were sold into slavery in the Spanish markets. Beatriz then took her deceased husband's place as Lord of La Gomera and El Hierro, ruling for over ten years until their son, Guillén Peraza de Ayala, was old enough to rule himself.
