Colchester started life as Colchester Town. In 1937 it was felt the club should turn professional but this was resisted by some. As a consequence, a breakaway club was formed and Colchester United was born. The new club progressed well and were finally elected to the football league in 1950.
Since then, the club have had a brief drop into the 5th tier in the early 1990’s and a brief rise into the Championship between 2006 and 2008. In 2006 they finished second in the 3rd tier (just behind their Essex rivals Southend Utd) to gain promotion to the Championship. They played just two seasons in the Championship before being relegated back to the 3rd tier. Another relegation in 2016 dropped them back to League 2 – some 18 seasons after they last played in the 4th tier.
Colchester are one of 2 professional clubs in Essex so it isn’t surprising that Southend United are their main rivals. Wycombe Wanderers and Ipswich Town are other rivalries for U’s fans.
The club originally adopted the Colchester coat of arms as their club crest. But there was a dispute with the local authority in the 1930’s about the use of this logo and this forced a rebranding. Since then, the crest has featured an eagle. The U’s are sometimes also known as The Eagles and their mascot is called Eddie!
