The personal rule of Gearóid Mór FitzGerald, 8th Earl of Kildare, is brought to an end on February 27, 1495, when he is arrested in Dublin by the Lord deputy Sir Edward Poynings and sent to the Tower of London to await trial for treason.

FitzGerald is Ireland’s premier peer and serves as Lord Deputy of Ireland from 1477 to 1494 and again from 1496 to 1513. His power is so great that he is called “the uncrowned King of Ireland.”

Gerald FitzGerald is appointed Lord Deputy in 1477, but is replaced by Lord Grey of Codnor on the supposition that an Englishman can do a better job. The Lords of the Pale set up a breakaway Parliament in protest, and Edward IV is forced to re-install FitzGerald. He inherits the title of Earl of Kildare in 1478.

FitzGerald manages to keep his position after the York dynasty in England is toppled and Henry VII becomes king, but FitzGerald blatantly disobeys King Henry on several occasions. He supports the pretender to the throne of England and the Lordship of Ireland, Lambert Simnel. However, Henry needs FitzGerald to rule in Ireland but, at the same time, he cannot control him. Simnel’s attempt to seize the throne ends in disaster at the Battle of Stoke Field and many of his supporters are killed. Henry, now secure on his throne, can afford to be merciful and pardons both Simnel and Kildare. Kildare is shrewd enough not to commit himself to the cause of the later pretender, Perkin Warbeck, despite Henry’s caustic comment that the Irish nobility would crown an ape to secure power for themselves.

FitzGerald presides over a period of near independence from English rule between 1477 and 1494. This independence is brought to an end on February 27, 1495 when his enemies in Ireland seize power and Lord deputy Sir Edward Poynings has him sent to London as a traitor. With FitzGerald’s absence, the way is cleared to end the independence of the Irish Parliament. Poynings directs the Irish Parliament, which is sitting in the town of Drogheda, to pass legislation making it subordinate to the English Parliament in Westminster. This marks the end of medieval Ireland and the commencement of the period of Tudor rule.

FitzGerald suffers another blow when his wife Alison dies soon after his arrest. He is tried in 1496, and uses the trial to convince Henry VII that the ruling factions in Ireland are “false knaves.” Henry immediately appoints him as Lord Deputy of Ireland and allows him to marry Elizabeth St. John, a distant cousin of the King. FitzGerald returns to Ireland in triumph.

He rules Ireland with an iron fist. He suppresses a rebellion in the city of Cork in 1500 by hanging the city’s mayor. He raises up an army against rebels in Connacht in 1504, defeating them at the Battle of Knockdoe. In 1512, after entering O’Neill of Clandeboye’s territory, capturing him and taking the castle of Belfast, FitzGerald proceeds through to utterly ravage the Bissett family’s lordship of the coastal Glens of Antrim.

The following year, while on an expedition against the O’Carrolls, he is mortally wounded while watering his horse in Kilkea. He is conveyed back to Kildare where he dies on or around September 3, 1513.
