Okay, mainly I my knowledge of history is limited to modern history. So as such the term the Third Reich often pops up, of course. However this begs an obvious question which for some reasons I've just never known, if Nazi Germany is the third reich, what are the 1st and 2nd?

My guesses where that the first was the Holy Roman Empire, and the second was the Kaisers Germany that ended when Germany lost WW1. Is that at all correct? That's just me guessing.
