2 years after the original 5 series ended in 2013, the BBC announced its revival. The show returned, revamped with a new format; each episode would take an in-depth look at a different historical ruler.

A largely new cast and production team assembled and six of Britain's top comedy talents guested as a historical ruler; Lorna Watson as Boudicca, Ben Miller as King John, Kevin Eldon as William the Conqueror, Rowan Atkinson as Henry VIII, Tom Rosenthal as King Alfred and Kathryn Drysdale as Cleopatra. Four original stars reprised their roles from previous series; Simon Farnaby as George III, Jim Howick as Napoleon and Winston Churchill, Sarah Hadland as Queen Victoria and Lawry Lewin as Oliver Cromwell. New cast member Jessica Ransom completed the line-up as Mary Queen of Scots.

Although a different format, the show retained much of its identity​, not least with Rattus Rattus returning to host.
