The kinds of resources available on the web — some scholarly, some entertaining, some put together by academics, some by amateurs — is overwhelming. I’ll try to point out a few interesting sites as we go along.
For lots of pictures and a nice historical overview, take a look at the Official Site of the Chateau of Versailles. To learn more about the Sun King, Louis XIV, you’ll get a lot out of this website.
And there are great images and chronologies and texts devoted to the English Civil Wars of the 17th c. See this on on the Glorious Revolution of 1688.
