The Unity first entered competitive football in 1883–84, with an entry for the
Birmingham Senior Cup and the Walsall Cup. In the former, the club lost to Sutton Coldfield in the first round, after two replays. In the latter, the club beat
Aston Victoria in the first round, but lost to West Bromwich All Saints in the second. The club competed in the
FA Cup in the
1887–88 season. In the first round, the Unity was beaten by
Stafford Road of
Wolverhampton, but the
Football Association ordered a replay as only seven of the Stafford Road players were eligible for the tournament. Rather than replay the tie, the Roadsters scratched, and played a friendly against the Unity on the due date (which ended 1–1). In the second round, the Unity came from 2–1 down to beat
Burton Swifts 5–2 away from home. The Unity beat
Birmingham Excelsior away in the third but were finally downed by
Bootle in the fourth, amid controversy; the
Sporting Life judged Bootle's winner to have been offside, and the Unity made protests against the eligibility of six Bootle players. By the time the appeal had been heard, Bootle had been knocked out by the
Old Carthusians, and the FA had little appetite for finding in the Unity's favour in such circumstances. The club's achievement at least earned it an invitation to the West Bromwich Charity Cup at the end of the season, and it reached the final, albeit then going down 10–1 at FA Cup winners
West Bromwich Albion. It continued to play in the qualifying rounds over the next few seasons, but never made the main stages of the competition. It was disqualified after beating
Kidderminster in the third qualifying round in
1890–91, after a protest by
Langley Green Victoria (whom Unity had beaten in the second round) over the eligibility of Unity's Pittaway; the protest was lodged too late to help Victoria, but it did help Kidderminster. In 1889–90 the club was one of the founders of the Birmingham and District League; it later dropped out but resumed membership of the league for the season of 1891–92, but did not complete the season. The final reported competitive matches for the club are in the 1895–96 season, in the West Midland League for amateur and reserve clubs, and the last matches in toto are recorded in 1897. ==Colours==
