Since the middle of the 19th century, the number of newly educated women teachers seeking the same employment and rights as their male counterparts has been rising. However, this was not the case and they encountered various forms of discrimination. Accordingly, they join forces to fight for their rights. In the first half of the 20th century, a large number of women teacher associations were formed, in which they are sometimes the same members as they have similar rules and activities. They all preserved their rules that show us the set structure and functioning of associations. Based on the material of the Association of Women Teachers of the Kingdoms of Croatia and Slavonia from 1904 and the Association of Women Teachers of City Children's Shelters in Zagreb created in 1933, something more is learned about their professional, humanitarian and social work. Within the association, teachers trained professionally, fought for a better position like trade unions and liaised with other associations for general wellbeing. Humanitarian work remained best remembered and documented since they devoted most of their work to the care and education of children. The Women Teachers' Association launched child welfare institutions in Zagreb such as cradle, asylum, shelter and children's home, and women teachers from the Association continued their work in shelters.
