Constituent Unions

Imperial College London was founded in 1907 through the merger of a number of smaller scientific and engineering teaching institutions. When these institutions united, their students' unions also came together to become Imperial College Union (ICU). Decades later, after absorbing several medical schools, their students' unions were also merged into ICU.

Maintaining the history

The distinctions between the different schools, and their diverse areas of research and teaching, can be seen in the College as the Faculties of Science, Engineering, and Medicine.

At ICU, they live on as the Constituent Unions, of which there are five. The Constituent Unions are fully integral parts of ICU, collectively forming a single organisation. Each Constituent Union has its own President and executive, and supports its own events, clubs and societies, as well as collaborating with the Academic and Wellbeing Representation Networks.

Unique to Imperial amongst students' unions in the UK, our Constituent Unions maintain the rich history and independent identities of the various communities within the wider Imperial student body. Each Constituent Union has its own set of historic mascots and traditions, as well as healthy rivalries with each other, all of which are familiar to Imperial students to this day.

Imperial College School of Medicine Students' Union

The ICSMSU represents undergraduate students in the Faculty of Medicine, including Medicine, BSc Medical Biosciences, and intercalated BSc students. It was founded from the merger of the students' unions of the Charing Cross & Westminster, Royal Postgraduate, and St Mary's Hospital Medical Schools between 1988 and 1997 as they each became part of Imperial College London.

The ICSMSU's mascot is the Phoenix, holding a blue fleur-de-lis in its right foot (for St Mary's) and a red cross in its left foot (for Charing Cross). The Phoenix is represented at ICSMSU events by the Phoenix Suit, worn by the braver ICSM students at inter-Constituent Union sports fixtures.

Royal College of Science Union

The Royal College of Science Union (RCSU) represents all Undergraduate students in the Faculty of Natural Science. Founded in 1881 alongside the Royal College of Science itself, legend has it that science fiction writer HG Wells was its first student leader.

The RCSU's mascots are:

  • Theta: A 100lb+, seven-foot-long stainless steel thermometer. The current Theta is Theta IV, as Thetas I - III have been lost to history through mascotry
  • Jezebel: A 1916 Dennis 'N' Type fire engine that saw action in Zeppelin raids on London in the First World War and gets four miles to the gallon

Royal School of Mines Union

The Royal School of Mines Union (RSMU) represents all undergraduate students in the Department of Materials and the Department of Earth Science and Engineering.

The Royal School of Mines was founded in 1851 as an institution dedicated to geology and metallurgy. The RSMU dates back to at least 1902, when the first Varsity match against the Camborne School of Mines was played, an intense rivalry that lasts to this day.

The RSMU's mascots are:

  • Clementine II: A 1926 Morris 'T' type truck purchased by the RSMU in 1960
  • Davy II: A 132lb, three-foot-tall mining lamp made of brass and aluminium.

Silwood Park Students' Union

The Silwood Union represents students based at the Silwood Park campus, which focuses on ecology, evolution and conservation. As these students are distant from the main South Kensington campus, the Silwood Union organises local events and activities for their members.
