The origin and development of social work can be traced back to the late 19th and early 20th centuries when societal changes and industrialization led to increased urbanization and social challenges. The roots of social work can be found in various movements, including the Charity Organization Societies (COS), settlement house movement, and the emergence of professional social work education.
