Thomas Osborne, 1st Duke of Leeds, KG (20 February 1632 – 26 July 1712) was an English Tory politician and peer.^[1] During the reign of Charles II of England, he was the leading figure in the English government for roughly five years in the mid-1670s. Osborne fell out of favour due to corruption and other scandals. He was impeached and eventually imprisoned in the Tower of London for five years until James II of England acceded in 1685. In 1688, he was one of the Immortal Seven who invited William of Orange to depose James II during the Glorious Revolution. Osborne was again the leading figure in England's government for a few years in the early 1690s before dying in 1712.^[2]
