I’ve been using the connections of classical and medieval history to push the connected topics. This yielded the observations that I don’t have much to say about particular nations except at a broad, general level before about the 18th century, and that I have little to say about Greece before the 19th century, considering how important it was in classical and medieval times. I did manage to introduce the topic of international government to the United States.
Early classical history has been covering much the same ground of interconnections among nations, This part is rather slow-growing. It suggests various ideas while I am working on it, but nothing remarkable enough to stick in the memory and write about later.
