History textbooks on the 1918-1919 revolutions in Hungary (1920-1984)

History texbooks have never relied exlusively on the state of the art; they were always overwhelmed by the political developments of the era. Following a particular topic of history books through the ages can tell a lot not only about the given question, but also about the politics and prevailing ideologies of those times. Such an inquiry is especially interesting, if the topic is the assessment of the revolutions of 1918 and 1919.
