A joint episode of a town in Hajdú-Bihar County and a village in Tolna county was written in Hungarian history of the 20th century. The politicians of the post-war coalition period began to write the story, the completion of which was very much urged by the expectations of the masses, the irresponsible promise of a carefree new life, a feverish campaign, and perhaps a compulsion resulting from being a war loser. In the history of Derecske and Györköny, the common chapter was forced by internal migration processes that started in 1945 resulting from the land reform and the relocation of the Hungarian Germans in close connection with it. I have tried to explore the events so that we could remember, together with the people of the Tiszántúl Region, to what had happened. In quest of finding the truth, I have called not only the press articles of the time and literature for help, but also the memories of those who directly lived through the events. The bitter consequences of the political decisions of that time were shared by settled Hungarians and indigenous Germans.
