Columbus’s finding that the West Indies were near the coast of India was not convincing enough. Magellan believed that there was a western sea route to reach the Spice Islands. He wanted to go on a voyage to discover this sea route. He sought financial aid from the Portuguese King, but the King was intent on developing a route to the East around the Cape of Good Hope. He refused to give Magellan the support he needed.
A vexed Magellan renounced his Portuguese citizenship. He relocated to Spain in 1518, and sought the help of the king of Spain.
He got a positive nod from the king. Magellan intended to search for a passage around the south of America into the Pacific Ocean.
He was given the financial support he needed and also provided a fleet of five ships. But the Spanish king did not provide funds for the crew.
This did not discourage Ferdinand Magellan. He recruited sailors by himself.
