Abstract
This chapter introduces readers to classical and contemporary definitions of citizenship, the development of the nation-state, and the concept of national identity as well as other forms of identity construction. The chapter also focuses on diaspora literature and introducing the classical and contemporary characterizations of diaspora and theories on diaspora politics. Concepts such as hybridity and transnationalism are briefly presented as these concepts feed into the contemporary definitions of diaspora, which are less focused on a place of origin or homeland attachment. The chapter also delves into the Othering of national politics toward diasporic communities, providing examples from recent American policy.
