Alexander McCabe (Irish: Alasdar Mac Cába), teacher, revolutionary, Sinn Féin politician, and founder of the Educational Building Society (EBS), dies in Dublin on May 31, 1972.

McCabe is born in Keash, County Sligo, on June 5, 1886. He is educated at Summerhill College, Sligo. He wins a scholarship to St. Patrick’s College of Education, Drumcondra, Dublin, and later obtains a diploma from University College Dublin (UCD). He is appointed headmaster of Drumnagranchy national school, County Sligo, in 1907. He joins the Irish Republican Brotherhood (IRB) in 1913.

McCabe is elected as a Sinn Féin MP for the South Sligo constituency at the 1918 Irish general election. In January 1919, Sinn Féin MPs refuse to recognise the Parliament of the United Kingdom and instead assemble at the Mansion House in Dublin as a revolutionary parliament called Dáil Éireann, though McCabe does not attend as he is in prison in Lincoln Gaol.

At the 1921 Irish elections, McCabe is re-elected for Sligo–Mayo East. He supports the Anglo-Irish Treaty and votes in favour of it. He is again re-elected for Sligo–Mayo East at the 1922 Irish general election, this time as pro-Treaty Sinn Féin Teachta Dála (TD). During the Treaty debate, he asserts that the counties of Ulster which comprise “Northern Ireland” can never be incorporated into an Irish Republic while the British Empire is what it is.

At the 1923 Irish general election, McCabe is elected as a Cumann na nGaedheal TD for Leitrim–Sligo. He resigns from Cumann na nGaedheal in 1924 because of dissatisfaction with government attitude to certain army officers and joins the National Party led by Joseph McGrath.

McCabe resigns his Dáil seat on October 30, 1924, along with several other TDs, and the resulting by-election on March 11, 1925, is won by the Cumann na nGaedheal candidate Martin Roddy. He does not stand for public office again and returns to his post as a schoolteacher.

In the 1930s McCabe is involved with the short-lived but widely followed Irish Christian Front (ICF), serving as the organisation’s secretary and announcing its creation to the public on August 22, 1936. He is also a member of the Blueshirts during this period and later the Irish Friends of Germany (later known as the “National Club”) during World War II, a would-be Nazi Collaborator group in the event Germany were to invade Ireland. He chairs their meetings, denies the group is a fifth column and expresses the belief that a German victory will lead to a United Ireland. He is interned in 1940–41 because of his pro-German sympathies, which he claims resulted from the desire to “see the very lifeblood squeezed out of England.”

In 1935, McCabe co-founds the Educational Building Society with Thomas J. O’Connell. He retires from teaching in the 1940s and becomes the full-time managing director of the EBS.

McCabe dies in Dublin on May 31, 1972, leaving his wife, son, and three daughters. There is a bronze bust of him in the headquarters of the Educational Building Society, Westmoreland Street, Dublin.
