Spain did have an empire, and a fairly massive one at that. It had just about all of Central America, all of South America save Brazil, and also huge chunks of North America such a Florida, Texas, California, and at some point large parts of the Louisiana Territory. Like most colonial powers, Spain also had bits of Africa.

Although I don't have sources for that and am certainly no kind of historian, I think this is pretty basic world history knowledge. So my question for OP is how do you see the British Empire having been different from the Spanish one, and what in particular about the Spanish Empire doesn't measure up to the British counterpart in your view?
