Magellan attempted to receive funds from the King of Portugal, but he would not fund this voyage because he saw no need for such a frivolous expenditure. Magellan then turned to King Charles (also known as Holy Roman Emperor Charles V) of Spain for support. Magellan convinced the king that this voyage would be useful to show that the Spice Islands were property of Spain, not Portugal. The dispute over these islands was significant because the possession of these islands would bring vast wealth to the owner. King Charles I saw this as an opportunity to gain status and wealth for his country and gave Magellan his funding.
