The club was founded in 1908 as
Cambridge Town F.C. (
Cambridge had not been granted
city status at that point) by the committee of the Cambridge St. Mary's club, and were committed to amateur sport. The club competed in the
Southern Amateur League, developing a fierce rivalry with
Ipswich Town that was evident both on and off the pitch. In 1912 they won the
Challenge International du Nord in 1912, beating
US Tourquennoise 4–1. The club were invited to join the newly formed
Eastern Counties League in 1935, but declined the invitation and switched instead to the
Spartan League. The resumption of football after the
Second World War saw Cambridge Town continuing in the
Spartan League, winning the competition 3 times between 1945 and 1950, before joining the
Athenian League for the 1950–51 season.
Cambridge was formally granted city status in April, 1951. Both Cambridge Town and their neighbours Abbey United applied to change their name to Cambridge City. Cambridge Town's application was approved because it arrived first and therefore Abbey United changed their name to
Cambridge United. In the same year, Cambridge City joined the Southern League Premier Division, aligning itself with other semi-professional and professional clubs seeking advancement toward the Football League. Professional status allowed the club to attract higher-caliber players and enhance its competitiveness. Additionally, they invested in improving their home ground, Milton Road, to meet league standards and accommodate rising attendances. Under the professional structure, City developed a more disciplined training regime and expanded its administrative staff, signalling its intent to become a major force in the region. Although Cambridge City never achieved Football League membership, the 1958 professional shift established a foundation for future success, particularly during the 1960s when the club enjoyed strong Southern League campaigns. This move epitomized the ambitions of mid-century regional clubs striving to bridge the gap between non-league and professional football. The club went on to make five applications to join the Football League between 1959 and 1974, all of which were unsuccessful.
Cambridge United were elected into
the Football League in 1970, and from that point City struggled to attract as many supporters to their games as their cross-city rivals – by the early 1980s, when United were enjoying a prolonged spell in the Second Division, City were attracting fewer than 200 supporters to each game. 1975–76 saw the second relegation in the club's history, into the Southern League's Division One North. They remained there until 1979–80, when a re-organisation of the league's structure, in order to become a feeder to the newly formed
Football Conference, placed City in the Midland Division. A switch was made to the Southern Division in the 1982–83 season and this seemed to coincide with a turnaround in City's fortunes, and 1985–86 saw City win the division on goal difference and gain promotion back to the Premier Division. The late 1980s through to the early 1990s saw City competing at the top of the Premier Division. City suffered a last day relegation at Atherstone United in May 1996, only to be reprieved. After a few seasons struggling at the wrong end of the table, including another reprieve from relegation in 1999, City's league form improved at just the right time and the club joined the
Football Conference's newly formed
South Division in 2004–05, embarking on a successful
FA Cup run in the same season – following United's relegation from the League in 2005, the two Cambridge clubs were only one division apart. However, the club was encountering financial difficulties and the City Ground was sold to an Isle of Man company called Ross River, which was linked to Brian York, a man who had briefly been a director of the club. The board announced that it was to scrap the first team and transform the reserve team into a feeder for Cambridge United. This prompted the formation of a
supporters' trust, who within weeks had taken over the running of the club. though the original deal was not overturned. In May 2008 City were demoted from the Conference South, after their ground failed an FA inspection, to the
Southern League Premier Division for the 2008–09 season. They were transferred into the
Isthmian League Division One North for 2019–20, before switching to the Northern Premier League Midlands Division for the start of the 2021/22 season. ==Colours and badge==
