When Poland regained independence it was crucial to unite school systems of all polish lands under one governance, as well as to prepare projects of school acts, that would apply to all country. Most important was to unify system, its organization, language of lectures etc. in the whole country. In accordance with Ustawa o ustroju szkolnictwa dated 11th March 1932 school system was to be based on seven-year 3rd degree public school. It was assumed, that schools would prepare talented children and adolescents to promotion from one type of school to the other, as well as to promotion from lower degree schools to higher degree schools. „Wiadomości Historyczno-Dydaktyczne” were one of the journals published between 1933 and 1939 by Polish Historical Society for history teaching. Editor-in-chief was Kazimierz Tyszkowski, who after 1937 functioned together with Antoni Knot. Articles concerning teaching of history in secondary school, especially concerning introduction of new programs, were published in „Wiadomości Historyczno-Dydaktyczne”. Taking into account the need to organize school system after more than 100-years dependence from invaders governance, should not be surprising, that it was developed fast, and not always proposed and implemented solutions were supported by the public, teachers and experts, what can be noticed when analyzing content of particular articles.
