The First Georgians: The Kings Who Made Britain was a series presented by Lucy Worsley which ties into an exhibition at Buckingham Palace this year to mark the 300th anniversary of George I taking the throne. The series (and presumably exhibition?) focussed on Georges I and II who are often overlooked a bit in the rush to get to George III and the madness and loss of the American colonies.
The last episode of Fit to Rule backed up a bit from the end of the second episode (post) to a time when George III was still on the throne and the future of the Hanoverian dynasty looked secure. His granddaughter, Princess Charlotte (daughter of the future George IV), had married and was expecting her first child.
