Rehabilitation psychology is a field in flux. With roots in the early legislation to protect those injured in the course of their job or duty (or both), the field now faces those very same issues again: (welfare) legislation of health care and provision of services to those injured in the course of their job and/or duty. This chapter outlines the path from then to now, and addresses the struggles and milestones the field has faced and crossed. Finally, in an attempt to place the field in a bigger context, a modest review of rehabilitation psychology efforts around the world is presented.
