In the end, members of all three clubs came together and on 17 June 1906 founded Olympia Oberschöneweide in the Großkopf tavern on Luisenstraße. The team initially consisted almost entirely of pupils and joined BTuFC Helgoland 1897 as a youth side a month later. That did not work out, so half a year later they moved again, this time to BTuFC Union 1892, the German champions of 1905. They spent two years there as the fourth team.\n\nIn 1907/08 they won the title in the lowest division of the Verband Berliner Ballspielvereine, their first more substantial success.
In February 1909 they broke away and wanted to stand on their own feet. In gratitude and solidarity they adopted both the name and the colours of Union.\n\nFrom then on they were Union Oberschöneweide, later with SC as a prefix, and wore blue and white.
