What was the reason Columbus sailed to the Americans?

Question

He wanted to find riches
He wanted to prove that the world was round
He wanted to prove his seamanship ••
He wanted to see India

Answer 1

I would vote for the riches :)

He was quite sure the world was round as were most navigators but he far underestimated the diameter and therefore thought he was in the East Indies when in fact he was in the West Indies :)
