History Today has a wonderful timeline of English and British monarchs. You click on one of them and get a brief summary (with a couple of dates) and their immediate predecessors and successors. You can then click on the name and get a list of articles on the monarch in question that is in the magazine's online archives. Then you have to subscribe to get to the archives but even without that subscription one can have a great deal of fun.
