Task: Question Generation
Input (English): Passage: The Bethencourt era ended in 1418 when Maciot sold his holdings and the rights to subjugate the remaining islands to Enrique Pérez de Guzmán. From this point on the intervention of the King of Castile increased. Between 1418 and 1445 dominion over the islands changed hands on a number of occasions. Finally, control over the conquered islands and the right to further conquests fell to Hernán Peraza The Elder and his children Guillén Peraza and Inés Peraza. The death of Guillén Peraza in the attack on La Palma has been immortalized in a moving lament. After the death of her brother Inés and her husband Diego García de Herrera became the sole rulers of the islands until 1477 when they ceded La Gomera to their son Hernán Peraza The Younger and the rights to the conquest of La Palma, Gran Canaria and Tenerife to the King of Castile. 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 due to outrages committed by the rulers on the native Gomeros. The last one, in 1488 caused the death of the islands ruler, Hernán Peraza, whose widow, Beatriz de Bobadilla y Ossorio, 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.
Output (English): What year did the rebellion end?
