Social group work began in the late 19th/early 20th century influenced by settlement houses, progressive education, and democratic ideals. It grew out of informal organizations in the US and was established as a method in social work education in the 1930s-1940s. Key figures helped define it as distinct from group psychotherapy. It was introduced globally in social work schools by the 1950s and continued developing new techniques. In India, it began in the 1930s in social work schools and was emphasized in programs in the 1960s, mainly using the American theoretical framework until recent indigenization efforts.
