NUSU is made from a merger of several earlier student organisations. The oldest of these was the Junior Union Society, founded in 1881, which arranged debates and dances for the Durham colleges in Newcastle. From 1914 to 1925 Newcastle Union Society and the
Durham Union Society collaborated with a shared president and vice-president selected alternatively from the two divisions. The previous Union Society dealt almost solely with student societies and entertainment and was governed by a Union Management Committee. The committee was composed of the President (in the Chair), the Lady President, two Vice Presidents (one male, one female), the Secretary, and various members of staff from
King's College (including the Bursar and the Society Steward). This structure remained in varying forms until the 1950s. The Students’ Representative Council (SRC) of
Armstrong College was formed in 1900 to represent all students, in matters of policy, to the Board of Professors. It remained a separate entity from the Union Society. In 1937 it became the SRC of King's College, and subsequently for Newcastle University when it disaffiliated from
Durham University in 1963. The Union Society became a
limited company, with a board of trustees, in 2009. In 2011 it also became an independent charity after completing the legal requirements and registering with the
Charity Commission. This coincided with a name change to Newcastle University Students’ Union (NUSU). In 2017, the Students' Union voted to rename the student bar from
Mensbar to ''Luther's
, to commemorate the 50th anniversary of the honorary doctorate awarded to Martin Luther King Jr. by the university in 1967. The previous name came from the fact it was initially male-only, originally Men's bar'', and from the motto - ‘Mens Agitat Molem’ – of the Armstrong College. In May 2016, NUSU held a referendum on their membership of the NUS. A 67% majority of students voted to end the affiliation. The then NUSU president Dominic Fearon said students felt the NUS “no longer represents their views, does not prioritise correctly, and is not effective at achieving change.” A second referendum was held in December 2018 with the result being to not re-affiliate with 52% of the vote, and a turnout of only 4%. ==Clubs and societies==
