After many difficulties, through a combination of good luck and persuasiveness, he gained the support of the Catholic monarchs, Isabel and Fernando.

The widely published report of his voyage of 1492 made Columbus famous throughout Europe and secured for him the title of Admiral of the Ocean Sea and further royal patronage. Columbus, who never abandoned the belief that he had reached Asia, led three more expeditions to the Caribbean. But intrigue and his own administrative failings brought disappointment and political obscurity to his final years.
