Founded in 1893 as a cricket club, B.93 began playing football in 1895 and entered DBU's first-team tournament in 1896, marking the beginning of its official football history. The club participated continuously in the top league from the start of the Denmark tournament in 1927 until 1954, when it was relegated to the
2nd Division. B.93 enjoyed its most successful period during the 1930s, earning the nickname
Champagneholdet ("The Champagne Team") and winning five
Danish championships. B.93 experienced a notable decline in prominence from the mid-20th century. The club's most recent stint in the top league was during the
1998–99 season. Prior to that, B.93 had played in the top league uninterrupted from 1975 to 1983. A highlight of this period was in 1982, when B.93 reached the
Danish Cup final. The club defeated
B 1903 over two legs at
Københavns Idrætspark, with the first match ending 3–3 after extra time and the replay won 1–0. This victory secured B.93 a place in the
UEFA Cup Winners' Cup, where the club eliminated East German club
Dynamo Dresden in the first round but was subsequently defeated by Belgium's
Waterschei Thor in the second round. The early 2000s were marked by financial difficulties for B.93. In February 2002, the club faced a bankruptcy crisis, which was averted when IT millionaire Thomas Olsen and former
Denmark international Preben Elkjær took over the professional company B.93 Copenhagen A/S. However, the partnership ended in June 2004, leading to a decline in the club's performance and relegation from the second tier in 2005. The decline continued, and in 2012, B.93 were relegated from the 2nd Division East, falling outside divisional football for the first time in its history. Despite this setback, the club was promoted from the
Denmark Series the following year and has remained a divisional team since. ==Honours==
