1420

In 1420, the Norman lords consolidated their dominion over the islands of Lanzarote and Fuerteventura, marking a significant milestone in the history of the Canary Islands' conquest. This process was led by Jean de Béthencourt and Gadifer de La Salle, who had begun the conquest in 1402. The consolidation of Norman control was crucial for establishing a feudal structure on the islands, introducing new forms of social and economic organization. This dominion facilitated the expansion of European influence in the archipelago, serving as a base for future conquests on the other islands. Additionally, Norman control allowed for the development of agriculture and trade, integrating Lanzarote and Fuerteventura into Atlantic trade routes. This event underscores the strategic importance of the Canary Islands in the context of European expansion into the Atlantic during the 15th century.
