The conquest took place between 1402 and 1496. It was not an easy task, militarily, given the resistance of the Guanche aboriginals in some islands. Nor was it easy politically, given the conflicting interests of the nobility (bent on fortifying their economic and political power) and the state, particularly Castile, with an interest in reinforcing its own power in competition with the nobles.
