The castle at Maynooth, which for several centuries was one of the largest and strongest in Ireland, was built by Gerald, the fifth earl, in 1427, whose second son was the founder of the house of Ormonde and was created earl of that name. For sixteen generations the earls of Kildare were the most active men in Ireland, and the history of their adventures would fill a book as big as a dictionary. There was always "something doing" wherever they went; they were on all sides of all questions and were sometimes fighting each other as fiercely as the family foes. They led rebellions against their sovereign, have suffered imprisonment, and have been executed at Tyburn and the Tower. They have been the boldest and most powerful defenders of British authority in Ireland and several times have saved the island to the British throne. More lords lieutenants have come from the Kildares than from any other family, and among the long list of earls have been some splendid characters. The eighth earl subdued all the native chieftains and made them submit to English authority. An early historian describes him as "A mightie man of stature, full of honoure and courage, who has bin Lord Deputie and Lord Justice of Ireland three and thirtie yeares. He was in government milde, to his enemies stearne, he was open and playne; hardley able to rule himself, but could well rule others; in anger he was sharp and short, being easily displeased and easily appeased." Thomas Gerald, the twelfth earl, having incurred the enmity of Cardinal Wolsey, was called to England and committed to the Tower for treason. When he left Ireland he intrusted his official authority and responsibilities to his son and heir, familiarly known as "Silken Thomas," because of the gorgeous trappings of his retinue. The boy was then but twenty-one, bold, brave, patriotic, and generous, and became the victim of a plot devised by agents of Cardinal Wolsey, who spread a report that his father had been beheaded in the Tower. The impetuous young lord left the Castle of Maynooth, rode into Dublin, and, entering the chamber where the council sat, openly renounced his allegiance to the King of England, gave his reasons and laid mace and sword, the symbols of office, upon the table. Archbishop Cromer, the lord chancellor, besought him to reconsider, explaining that the rumor from London might be false, and the young earl was about to yield when the voice of the family bard, who had followed him to Dublin, was heard through the window singing the death song of the Kildares. "Silken Thomas" seized his sword, summoned the Geraldines, the family clan, which was the mightiest and most numerous in Ireland, assaulted the castle, and soon involved the entire country in a desperate revolution. When the old earl heard the news in his cell in the Tower he sent a message to Henry VIII. asking pardon for the rashness of his son and then died of a broken heart.
