Patrick Augustine Sheehan was an Irish Catholic priest, author and political activist. He was usually known as Canon Sheehan after his 1903 appointment as a canon of the diocese of Cloyne, or more fully as Canon Sheehan of Doneraile, after the town of Doneraile where he wrote almost all of his major works and served as parish priest.

The All-for-Ireland League (AFIL) was an Irish, Munster-based political party (1909–1918). Founded by William O'Brien MP, it generated a new national movement to achieve agreement between the different parties concerned on the historically difficult aim of Home Rule for the whole of Ireland. The AFIL established itself as a separate non-sectarian party in the House of Commons of the United Kingdom of Great Britain and Ireland, binding a group of independent nationalists MPs to pursue a broader concept of Irish nationalism, a consensus of political brotherhood and reconciliation among all Irishmen, primarily to win Unionist consent to an All-Ireland parliamentary settlement.
