The World War I brought political and social changes in the global scale. Transformations in that range occurred also on a local ground. Grudziądz in the end of 1918 or January 1920 was completely different in terms of political-social situation than in the mid-1914. The change of the state affiliation and political-administration transformations however were not the only ones that resulted as the consequence of a global conflict. The great war in 1914–1918 was the first case which directly affected not only the soldiers fighting in the first front line but also the citizens of the furthest supply base. The city and its citizens in those days experienced the difficulties of everyday existence. The transformations were occurring in all its aspects; nourishment, customs, daily schedule or healthiness among others. The war took its toll on all those and many other elements of everyday existence. Grudziądz, being the fortress city, filled with a strong military garrison during the whole war period, possessing also a complex ethnic structure, constitutes an interesting research object to carry out analysis about the history of past everyday life, both in the breakthrough and peaceful existence periods.
