Answer 1

On of them was that he would bring back more gold

Answer 2

 For a decade, Columbus approached the Portuguese king and the Spanish monarchs to obtain a grant to explore possible trade routes to the west. After initially turning him down, King Ferdinand and Queen Isabella reconsidered once the Moors had been successfully expelled from Spain in 1492. Columbus promised to bring back gold, spices, and silks from the Far East, to spread Christianity, and to lead an expedition to China. In return, Columbus asked for and got the hereditary title "admiral of the ocean seas" and became governor of all discovered lands.
