In Transnational Nationalism and Collective Identity among the American Irish, Howard Lune considers the development and mobilization of different nationalisms over 125 years of Irish diasporic history (1791-1920) and how these campaigns defined the Irish nation and Irish citizenship.

Lune takes a collective approach to exploring identity, concentrating on social identities in which organizations are the primary creative agent to understand who we are and how we come to define ourselves. As exiled Irishmen moved to the United States, they sought to create a new Irish republic following the American model. Lune traces the construction of Irish American identity through the establishment and development of Irish nationalist organizations in the United States. He looks at how networks-such as societies, clubs, and private organizations-can influence and foster diaspora, nationalism, and nationalist movements.

By separating nationalism from the physical nation, Transnational Nationalism and Collective Identity among the American Irish uniquely captures the processes and mechanisms by which collective identities are constructed, negotiated, and disseminated. Inevitably, this work tackles the question of what it means to be Irish-to have a nationality, a community, or a shared history.
