American social welfare began in the colonial period with the adoption of the Elizabethan Poor Laws as the basis for treatment of society's poor and deviant. By the beginning of the Progressive Era (1900), immigration, the Women's Movement, scientific investigation of social problems, and societal growth produced significant innovations in both public and private perceptions, programs, and treatment in such areas as poor relief, mental and physical health, and corrections, and led to the beginnings of professionalization of social work.

This article discusses the African American social welfare system that began to develop during the early 20th century. This social welfare system, designed by African Americans to serve African Americans, addressed needs that were not being met by any other formal social services while the nascent social work profession was emerging. The myriad programs included settlement houses, boys and girls programs, training schools, and day nurseries. The women’s club movement played a critical role in the development of this social welfare system and provided much of the impetus for change and inclusion. Through formal organizations, including the National Urban League (NUL) and the Universal Negro Improvement Association (UNIA), and an array of clubs and social groups, social services were extended to urban and rural communities throughout the United States.
Mentona Moser (1874–1971) was a pioneer of social work in Switzerland. Following the ideas of the settlement movement, Moser initiated and contributed to fundamental social welfare activities in Zurich until the end of World War I. As a communist, from the early 1920s on, she worked on several projects of radical social work in the context of the Red Aid.
