The main aim of this paper is to present the activity of Łódzkie Kuratorium Obywatelskie nad Rodzinami Rezerwistów during the World War I. It mainly refers to different types of aid and care of soldiers’ families, including child care. The historical-pedagogical research was conducted by using the source analysis method, which consists of finding facts and their general sense in the context of research questions. Kuratorium provided aid in the city in two forms. Mainly, it included monetary benefits granted to adults (mothers and closer relations) and children, which bought, most of all, food, medicines, and fuel. The other form of aid consisted in providing reservists’ children, orphans and half-orphans with places in orphanages orshelters in Łódź or at the children’s relations.
