This lecture series, first given on a speaking tour of the US, is interesting from several perspectives as these lectures are about the time period in which several of Thackeray's books are set, most famously [b:Vanity Fair|5797|Vanity Fair|William Makepeace Thackeray|http://d.gr-assets.com/books/1344386439s/5797.jpg|1057468], and very much reflect some of the more satirical elements of those novels. It was also interesting to get an insight into the frivolous Georgians from a more sober and socially aware Victorian point of view.
These are probably mostly of interest to Thackeray/Vanity Fair
fans but they are also, in some ways, valuable documents on Victorian thinking. What they aren't are potted biographies of the four kings concerned so it would be advisable to at least know the basics about Georges I, II, III & IV before reading.
