Profile — Facts, Figures and Milestones
1. FC Union Berlin (officially: 1. Fußballclub Union Berlin e. V.) is a football club based in Berlin-Köpenick. Its founding history is complicated. In 1906, in Luisenstraße (today's Plönzeile), ball boys and friends of the local club Excelsior gathered in a sandpit behind the Oberschöneweide school and founded the football club Olympia. The club dissolved shortly after, but some football enthusiasts from the same circle soon formed a new club, modelled on the neighbouring Lichtenberger S.C. Frisch Auf. Excelsior split into Preußen and Vorwärts, but neither offshoot lasted long.
Ultimately, members of all three clubs came together and on June 17, 1906, founded Olympia Oberschöneweide at the "Großkopf" tavern in Luisenstraße 17. The team initially consisted almost entirely of schoolboys and joined BTuFC Helgoland 1897 as a youth team barely a month later. The club was not very successful, so the Oberschöneweide players decided to switch again just six months later. This time they attached themselves to the 1905 German Football Champions — BTuFC Union 1892. There the team played for two years — albeit only as the fourth team. In the 1907/08 season, they achieved their first modest success by winning the championship of the lowest division of the Berlin Ball Sports Association (VBB). In February 1909, the team separated from BTuFC. They wanted to stand on their own feet. Out of gratitude and loyalty, they adopted both the name (henceforth calling themselves Union Oberschöneweide, later with the prefix SC) and the club colours blue and white.
Three years later, in the 1909/10 season, the Berliners first competed as an independent club in the VBB — quite successfully. After three promotions in five years, the club played in Berlin and Brandenburg's top division from 1914. In the new league of the Brandenburg Ball Sports Association, Union even became runners-up in 1917.
The team played for nearly ten years at a sports ground on Wattstraße in Oberschöneweide, until the 1920 move to the Sadowa sports complex — today's Stadion An der Alten Försterei — in the Wuhlheide forest. For the official opening ceremony on August 7, 1920, the reigning German champions 1. FC Nürnberg visited. In 1920, Union became Berlin champions for the first time and qualified for the German championship final round. They reached the quarter-finals and narrowly lost 2-3 to Vereinigte Breslauer Sportfreunde. In 1923, the club became Berlin champions again and, after victories over Arminia Bielefeld and SpVgg Fürth, made it all the way to the championship final. At the Grunewald Stadium in Berlin, Union lost their "home match" 0-3 against Hamburger SV in front of 64,000 spectators. The early heyday of "Union-Ob." — as fans called the club — came to an end.

The 1925 runner-up spot in Berlin and reaching the Berlin Cup final in 1926 were the only other significant achievements. From then on, clubs like Hertha BSC or Tennis Borussia Berlin dominated Berlin football. After the Second World War, the club initially continued as the communal sports group SG Oberschöneweide. In 1948, it was transformed into SG Union Oberschöneweide. And the club thrived — qualifying for the 1949 German Championship final round, only to be forbidden from travelling to Kiel for the match against HSV. In response, virtually the entire first team defected to West Berlin and left Union. The club changed its name in the GDR to BSG Motor Oberschöneweide and was incorporated into the VEB Transformatorenwerk Karl Liebknecht as a factory sports group. Until 1962, the club played predominantly in the GDR's third division. Only in the 1965/66 season did they earn promotion to the DDR-Oberliga.
The club benefited from politics in this regard. Herbert Warnke, chairman of the FDGB (Free German Trade Union Federation), demanded that a civilian football club be established for Berlin's working people. He succeeded. On January 20, 1966, "1. FC Union Berlin" was newly founded.
