April 29th , 1803
Paul Cardinal Cullen (29 April 1803 – 24 October 1878) was Roman Catholic Archbishop of Dublin and previously of Armagh, and the first Irish cardinal.
His Ultramontanism spearheaded the Romanisation of the Catholic Church in Ireland and ushered in the devotional revolution experienced in Ireland through the second half of the 19th century and much of the 20th century. A trained biblical theologian and scholar of ancient languages, Cullen crafted the formula for papal infallibility at the First Vatican Council.
Cullen was born at Prospect, Narraghmore, Athy, County Kildare, one of 16 children of Hugh and Judith (Maher) Cullen, six of whom were from Hugh’s first marriage. His first school was the Quaker Shackleton School in nearby Ballitore.
