In the early 1900s, Britain was a dominant imperial, military, and economic power. By the end of the century, the empire was gone and the country's international status had been eclipsed by the United States and the European Union. This course charts these developments through the impacts of the two world wars, decolonization, the welfare state, postwar affluence, youth cultures, "Thatcherism", and "New Labour". Course materials include historical analyses, contemporary documents, film, and music.
