Nevertheless, two years have passed until the match between two oldest clubs in the Kingdom of Serbia took place. On July 20, 1906, Šumadija and Soko met in Kragujevac, and Soko won by 6:1. In the rematch, on August 27, 1906, Soko won again, but this time more convincingly, with the score of 9:0. Unknown chronicle registered that the crown prince himself, George Karađorđević, was also present. For the history of Serbian football, it is very important to mention that these were the first matches played between two domestic clubs. This tradition of the rival matches between FK BASK (former SOKO) and FK Šumadija is held, since 1993, every year on St. George's Day, on May 6, and on Krstovdan, on September 14, when they celebrate their respective holiday Slava´s.
