"Royal Flash" is set during the Revolutions of 1848. The story features Lola Montez and Otto von Bismarck as major characters, and fictionalises elements of the Schleswig-Holstein Question, 1843, 1847 and 1848. It is set in the fictional Duchy of Strackenz, making it the only Flashman novel to be set in a fictitious location.
