What did the cubans have to do with the war?
The Cubans had to do with everything about the war. The Cuban rebellions were trying to gain freedom from Spain. If the Cubans didn't rebell, there would be no war.
Why did the cubans want freedom?
The Cubans wanted freedom for the same reason the young America wanted freedom. One of these were religious prosecution. The Cubans also wanted their own government and not be ruled by someone who was across the ocean. When Spain heard of this rebellion, they sent ships to cease the rebellion.
