The Cambridge Union Society, commonly referred to as “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 continually operating debating society in the world. Additionally, the Cambridge Union has served as a model for the foundation of similar societies at several other prominent universities, including the Oxford Union, Studentafton and the Yale Political Union. The Union is a private society with membership open to all students of Cambridge University or Anglia Ruskin University, and is completely separate from the Cambridge University Students’ Union. The Union became a registered charity in May 2010, and entered into a 3 year partnership with professional service providers Deloitte in November, 2013.
