This is the first publication about Bishop Teofil Bromboszcz. The importance of the biographical sketch of Bishop Bromboszcz lies in the fact that his activities were closely connected with the problems of Silesia in its crucial periods. Such periods in the history of Silesia were undoubtedly the years of the plebiscite and uprisings (1919-1922) and the interwar period (1929-1939).
