This course introduces students to key theories and concepts of international social work alongside critical decolonial theories and concepts that intervene into the body of literature about (international) social work. We will start with a historical account of the development, professionalization and institutionalization of international social work, followed by a critical decolonial and feminist reading of the Western narrative of social work’s history. Next, we will look at the "broad definition of international social work" (Midgley, 2001) and continue with an in-depth and critical reading of key texts, that deal with theoretical and conceptual issues of international social work such as globalization, migration, gender, (post-) development, human rights and decolonial social work and collective trauma.
