This is the first book to provide a broad yet balanced overview of the extraordinary events that led to the collapse of Hungary between October 1918 and March 1919. Pal Hatos reveals how, by the end of that period, Hungary had lost three quarters of its territory and was run by a brutal Bolshevik dictatorship. Combining social, political, and diplomatic history to show the rise and fall of the first Hungarian republic, Hungary's Collapse in the First World War provides a lively history of the 1918 revolution in Hungary. It offers a wealth of new and revealing information based on extensive research and a much-needed exploration of this critical period in Hungarian history.
