At the start of World War I, Transylvania was a multi-ethnic province that was still incorporated within the borders of the Austro-Hungarian Monarchy. The studies included in this collection show that the war and its propaganda affected the entire Transylvanian population, regardless of age, ethnic origin or social status. While some Transylvanians were required, by virtue of their profession, to enter the service of the Austro-Hungarian Monarchy’s propaganda machine, others chose to do so voluntarily or became the target population. The political and ecclesiastical authorities intended to persuade Transylvanians of the justness of the war and encouraged them to keep fighting and hold their ground, at home or on the front, wherever the war took them.
