Using Poland as example, the article explores the operation of east European communist welfare states, with particular attention paid to benefits offered to working mothers. By exploring a number of diverse sources, I analyze the evolution and the meaning of institutional care and maternity leave in the life of professionally-active women. Studying a variety of factors that shaped the welfare policies of the time, including post-war industrialization, consumption, the demographic panic, and the struggling economy of the twilight years of communism, I attach particular importance to the early 1970s, when Poland saw a particular shift in gender-equality discourse. Welfare benefits played a key role in communists states, serving as a guarantee of equal opportunities or, in the case of mothers, as a tool for potentially facilitating employment. In time, however, they became chiefly tools designed to control the population and female fertility.
