FSV Berolina Stralau  Friedrichshaner SV Berolina Stralau 01 is a German association football club from the city of Berlin. It is the successor to Berolina Berlin which was formed 1 July 1901 as "Berliner Fußball-Club Libertas-Südost Berlin". "Libertas" played in the Märkische Fußball-Bund, an early Berlin-based league active from 1901–11. They adopted the name "Berliner Sport-Club Berolina" in 1909 and became part of the Oberliga Berlin (I) in 1913. Generally a lower table side, the club's best results came as a 3rd-place finish in the MFB in 1910 and a 2nd place Oberliga finish in 1918. The team joined the "Berliner Turnerkooperation" in 1918 as that club's football department and maintained its identity as "Fußballabteilung Berolina der BT". They became independent again sometime in 1923. On 12 May 1926, "Berolina" merged with "Lichtenburger Sportclub 01" to form "Berolina-Lichtenburger SC 01". The Lichtenburg side was the product of 22 August 1919 union between "Lichtenburger Sport-Club 02" and "Lichtenburger Sport-Club Frisch-Auf". In 1933, German football was reorganized under the Third Reich in 16 top-flight regional divisions. Although "Berolina" never managed to qualify for play in the Gauliga Berlin-Brandenburg (I), they did advance to the first knock out round of the 1935 Tschammerspokal, predecessor to today's DFB-Pokal with victories over "SC Victoria Hamburg" and "Vorwärts-Rasensport Gleiwitz" before being eliminated 1:5 by "Berlin FC Hanau 93". Towards the end of World War II, "SC" became part of the wartime side "Kriegspielgemeinde Berolina/Stalau Berlin" alongside partner "Sportverein Stralau". Following the conflict occupying Allied authorities dissolved most organizations in the country, including football and sports clubs, as part of the process of de-Nazification. Many clubs were soon reestablished and the former membership of "Berolina" was reorganized as "Sportgruppe Stralau". Located in the Soviet-occupied eastern part of the country the team became part of the separate football competition that emerged in East Germany.
