The Fitzgeralds
In the years leading to the ascendancy of the FitzGerald family (1470–1535) Kildare came virtual capital of Ireland. The Irish Parliament sat in Naas on twenty occasions between 1255 and 1484, and there were also sittings in Kildare in 1266-67 and 1310, 12 in Castledermot between 1264 and 1509, Ballymore Eustace in 1390 and Great Connell Priory in 1478. English King Richard II took the submission of Irish chiefs at Great Connell Priory Augustinian Priory in 1395. in 1481, Gerald FitzGerald, Gearóid Mór, eighth earl of Kildare, was appointed English King's Deputy in Ireland by Edward IV. The principles of the county, Edmond Lane, Bishop of Kildare, the Prior of Great Connell Priory and Gearóid Mór all assisted in the coronation of the Yorkist pretender Lambert Simnel in Dublin but were pardoned by the new king Henry VII after Simnel's defeat.
In 1488 Gearóid Mór became one of first to use guns in Ireland, importing six handguns from Germany for his personal guard and using cannon to destroy Balrath Castle in County Westmeath. When he was established in 1496 as Lord Deputy of Ireland, English King Henry VIII's man in Ireland, the king allegedly said "if all Ireland cannot rule this man, let him rule all Ireland." In 1504 Gearóid Mór defeated Clanricard and O Bríain at Knockdoe, Co Galway, the most important battle of his career. Gearóid Mór rebuilt Athy castle to secure his southern frontier in 1506 but died in Athy in 1513 from gunshot wounds received in an engagement with O'Mores and was succeeded by Gearóid Óg. Gearóid Óg established Ireland's first University at Maynooth in 1518.
Even at the supposed height of their power, accusations by rivals that the family was plotting against Henry VIII bedeviled the FitzGerald dynasty. Gearóid Mór spent two years and Gearóid Óg 11 years in all as the King's prisoner in the Tower of London. In 1534 Gearóid Óg was recalled to London once more (February), leaving his 20-year-old son Silken Thomas in charge. Thomas declared rebellion (11 June) on false information that his father had been executed. In 1535 Maynooth Castle, stronghold of Silken Thomas, was bombarded by cannon for 18 days and taken by William Brereton. Rathangan castle was also taken before Thomas submitted in October. Despite a guarantee of personal safety, Silken Thomas and five uncles were executed in the Tower of London in 1537. Thomas's younger brother Gearóid was smuggled to Tuscany. The FitzGerald lands were confiscated and the biggest share-out of Kildare land since the Cambro-Norman conquest took place. In 1552 Gearóid the only survivor of FitzGerald family, was restored to his ancestral title and possessions.
