Slavia's B team competed in the tournament until 1909.[1] In 1949, the team entered the Oblastní soutěž, the second tier of Czechoslovak football, winning the title in 1958. During the 1960s, Slavia Prague B competed in the Second League, the Prague Championship and Divize B and Divize C, competing in the latter two competitions during the 1970s, before withdrawing from football from 1977 to 1984. During the 1980s, the team bounced between the third and the fourth tiers of Czech football, before the formation of the Bohemian Football League.[2]
Following the dissolution of Czechoslovakia in 1993, Slavia Prague B remained in the Bohemian Football League, winning the competition in 1997.[3] In 2011, Slavia Prague B finished 17th in the Bohemian Football League, being relegated into Divize A.[4] From 2012 to 2019, the team competed in youth football, before returning to the Bohemian Football League in 2019.[5] In 2022, Slavia Prague B were promoted in the Czech National Football League, the second tier of Czech football, after winning the Bohemian Football League.[6] In 2023, Slavia Prague B finished 15th in the 2022–23 Czech National Football League, being relegated back into Bohemian Football League.[7]
