There are many reasons but here's two
1. The 'war' and invasion etc was fought in the West so the province that you are going to have to raise troops and revenue from to fight the war is the same one where all the fighting takes place.
Meanwhile the 'East' had Anatolia as a heartland for revenue and recruits that was untouched .
<span>2. There is alot of evidence that it wasn't simply 'barbarian' invasion but also a large element of rebellion against central authority by local forces. These are the people who are supposed to supply your troops and revenue.</span>
From whats listed, it would be Drake, Francis Drake. He was not even Spanish. In fact, he was an English sea captain, navigator, privateer who later became the second highest rank officer in the English navy against the later battle against the Spanish Amanda. He first gain fame because of his work as an English privateer/pirate who raided Spanish ports/ships and ended up making England a lot of wealth. He became the second person to successfully circumnavigate around the world on sea in one expedition.<span />
It was forgotten in it's time because no one cared about being civil and listening to what EVERYONE wanted and being at peace with one another. They thought fighting in a war would help them simmer their dispute. Today, we don't fight over lands and things as much as we used to. While South America and North America are still fighting, *not in a huge war* it's not the same as it was then.
Cuba is what you are looking for.
