What occurred on this day through Irish history:
1534 - Thomas Garrett (Lord Offaly and grandson of Garret Mór Fitzgerald, Earl of Kildare), rides through Dublin with a large band of followers. Known as "Silken Thomas" because of the silk worn on his followers' helmets, he has heard the false rumor spread by Henry VIII that his father, Garrett Óg has been executed in the Tower of London. He enters the Chapter House of St. Mary's Abbey where the King's Council is awaiting him and flings down his Sword of State. This is a dramatic act of defiance, by which he hopes to force his claim to power. Henry VIII treats it as an act of open revolt and confines his father, Garret Óg, to the Tower where he dies two months later
