That's not to deny that there isn't an interesting point of view in exploring the connections among different threads of history. James Burke's fantastic Connections series comes to mind.

Some people are keenly interested in the history of their profession or hobbies. E.g. musicians interested in the history of music, or the development of their favorite instrument and such. Hackers, software devs and computer scientists interested in the history of computing and retrocomputing. Etc. Usually they are not into the political connection unless they are also interested in politics.
