It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
It depends on what you mean by capitalize. I'd say you should follow the normal rules of punctuation, unless you have reason to think that the context of the a particular historical even would make it more correct to do otherwise. A slogan such as "No taxation without representation" would generally rate at least one capital letter.
