A Ruritanian Romance is a story set in a fictional country, usually in Central or Eastern Europe.  The genre derives its name
from the country of  Ruritania, a fictionalized place in three novels by Anthony Hope, the first being the wildly popular
Prisoner of Zenda
.  Hope's success led to a new genre of novels featuring similar elements: mistaken identity, aristo-cratic
romance, intrigue, narrow escapes, and close calls.  The themes of honor, loyalty, and love predominate, and the books
frequently feature the restoration of kings to their thrones.     

Although recognizable Ruritanian romances such as Robert Louis Stevenson's
Prince Otto were written prior to Hope's The
Prisoner of Zenda
, that 1894 novel set the type, with the handsome decoy restoring the rightful king to the throne, and
resulted in a burst of similar popular fiction, such as George Barr McCutcheon's Graustark novels and Frances Hodgson
The Lost Prince.  Edgar rice Burroughs' contributions to this tradition were The Mad King, a novel, and "The Rider," a

The Mad King is one of his most popular non-series works.  He wrote the first half of the present book in October and
November of 1913 and submitted it for publication as "The Mad King of Lutha" to All-Story Weekly in 1914.  The success of
this novelette inspired a sequel "Barney Custer of Beatrice" in 1915.  Both novelettes were combined in 1926 to form the
present volume,
The Mad King.
