Reddit mentions of Germany and the Holy Roman Empire: Volume I: Maximilian I To The Peace Of Westphalia, 1493-1648 (Oxford History Of Early Modern Europe)

I am very much an amateur historian, I'm afraid - I even go so far as to use my girlfriend's access to academia, as I don't have the same privileges myself.

With that said, Joachim Whaley's two-volume history on Germany and Holy Roman Empire is beyond compare. I find his argument that the HRE was in a constant state of reform especially fascinating. Beyond that, he has an extensive bibliography of his own that might help you out. Sorry I couldn't be more helpful myself.

A brief search on Amazon yielded these four books -

Link 3 and what looks like a massive, multi-volume tome:

But just to start, check out this Wikipedia article, its in-text links and the external links.

Thanks for the answer!

Since you seem to know a lot about this subject, would this book be a good starting point in learning about the HRE?

Oooooh, I'm actually not all that familiar with Early Modern Germany, but I think I've found a few books that may help you with the religious, political and military aspects. Some of these books are pretty expensive, so I'd recommend finding a good library or seeing if your local library does inter-library loans with larger libraries. Usually you have to read the books pretty quick, but it saves paying $150 for a book if you're not in a position to do that. Just be sure to take plenty of notes!

I'd also be willing to look at what you've got but, like I said, I may not be as useful as I first thought.

This is part one of a two part set. I have not gotten through it all but it is a good textbook.
