King's College London Students' Union (KCLSU) is the oldest students' union in the UK. We were founded in 1873 as the Union Society of King's College London and then changed our name in 1908 to KCLSU. One of our early Presidents, Ivison Macadam, went on to become the founding president of the National Union of Students in 1922.
Every current student at King's is a member of KCLSU, and this includes Nobel Peace Prize winner the Most Revd Desmond Tutu FKC during his time at King's. A metal bust celebrating his time at King's was originally placed in KCLSU’s now closed nightclub on surrey street called Tutu’s. The bust was moved to Bush House in 2018 when KCLSU’s The Vault opened.
