Cambridge Union Society

The Cambridge Union Society, commonly referred to as simply "the Cambridge Union" or "the Union," is a debating society in Cambridge, England and the largest society at the University of Cambridge. Founded in 1815, the Union is the oldest student debate society in Britain and has developed a worldwide reputation as a noted symbol of free speech and open debate. Additionally, the Cambridge Union has served as a model for the subsequent foundation of similar societies at several other prominent universities, including the Oxford Union and the Yale Political Union. The Union is a private society, and is distinct from the Cambridge University Students' Union.

The Union has a long and distinguished history of hosting leading state and international political and other figures in its chamber, from Presidents to Prime Ministers and Oscar winners to Olympic legends. Over its history, these have included the Dalai Lama, President Ronald Reagan, Professor Germaine Greer, Prime Minister Winston Churchill and Clint Eastwood. Recent speakers include academic Richard Dawkins, former British Prime Minister John Major, former President of Pakistan Pervez Musharraf, comedian Dara Ó Briain, civil rights leader Jesse Jackson, Olympic legend Lord Coe, violinist and songwriter Diana Yukawa, actor Sir Ian McKellen and Wikileaks founder Julian Assange.
