Sir Winston Churchill in the context of "Oxford Union Society"

The Oxford Union Society is a debating society in the city of Oxford, England, whose membership is drawn primarily from the University of Oxford. Founded in 1823, it is one of Britain's oldest university unions and is widely considered as one of the world's most prestigious private students' societies. The Oxford Union exists independently from the university and is distinct from the Oxford University Student Union.

The Oxford Union has a tradition of hosting some of the world's most prominent individuals across politics, academia, and popular culture ranging from Albert Einstein and Elton John to Sir Winston Churchill, Ronald Reagan, Queen Elizabeth II and Mahathir Mohamad. Many former Presidents of the Union have gone on to hold high office in the UK and the Commonwealth including William Gladstone, Ted Heath, Boris Johnson, and Benazir Bhutto.

George Spencer, 4th Duke of Marlborough, KG, PC, FRS (26 January 1739 – 29 January 1817), styled Marquess of Blandford until 1758, was a British courtier and politician from the Spencer family. He served as Lord Chamberlain between 1762 and 1763 and as Lord Privy Seal between 1763 and 1765. He is the great-great-great grandfather of Sir Winston Churchill.
