The Canary Islands have been identified with a large number of the Atlantic myths of Antiquity and the Middle Ages. The fact is that they were inhabited by an aboriginal people, the Guanches, of whose history, origin, language and culture very little is known, since they were not known to the Europeans until 1312.
In the mid-14th century a number of expeditions by Mallorcans, Biscayans, Andalusians and Portuguese took place, and in 1344 Pope Clement VI grated the islands to the Castilian prince Luis de la Cerda with the title of 'Prince of La Fortuna', and preached a crusade for their conquest.
However, none of this produced any permanent results, and although several islands were subjugated, the complete conquest of the Archipelago did not come about until 1496.
