The National Portrait Gallery's history includes full color photos of portraits of some of the kings and queens. It details short biographies of the kings and queens of England that includes their personal lives and their reigns. It begins with an introduction detailing the ancient tribes' kings dating from BC through the ninth century in England. The biographies start with Alfred the Great in the mid-ninth century and end with the current monarch, Queen Elizabeth II. The familial connections and lines connecting kings as the crown passes from house to house down the generations can be hard to follow at times (what family tree isn't?).
While the biographies are fascinating--most share the sordid dramas, backstabbing, serial marriages and power plays that populated the royal circles back then (probably still do today), the copy editing missed enough typos and errors to be noticeable and distracting.
