Literary and filmic works, visual and oral narratives contribute to one's sense of belonging to an imagined community, whether to a domestic family, to a socio-cultural or religious group, or to a broader ideological and political system, such as a nation or empire. In addition to national literatures and films from Britain, Canada, and the United States, the field explores contemporary debates and theoretical developments in post-colonial, global, minority, indigenous, and diasporic studies (including Asian, Caribbean and African). Theoretical, cultural and historical concerns include those of war, imperialism, settlement, slavery, race, hybridity, mobility, globalization, human rights, and gender.
