Since the end of the nineteenth century, Ireland has witnessed a profound reconfiguration of its cultural, political, constitutional and religious identities, resulting in an unparalleled questioning of the dominant discourses and narratives that have seemingly defined the nation. The essays in this collection examine the ways in which established Irish socio-cultural structures of authority and their constructs of collective identity have been challenged within literary and cultural discourses of the twentieth and twenty-first centuries. Every challenge to the purported wisdom of these authority structures adds a new facet to the complexity of Irish national identity and contributes to the continuous evolution of the 'New Ireland', a phrase often used to signify the momentous transformations of the country in times of change.
