The Act of Union, coming into effect on 1 January 1801, portended the integration of Ireland into a unified, if not necessarily uniform, community. This volume treats the complexities, perspectives, methodologies and debates on the themes of the years between 1801 and 1879. Its focus is the making of the Union, the Catholic question, the age of Daniel O'Connell, the famine and its consequences, emigration and settlement in new lands, post-famine politics, religious awakenings, Fenianism, the rise of home rule politics and emergent feminism.
