Two dominant football clubs emerged in the city at this time, as the old guard of Saint Petersburg such as Sport and Unitas faded.
Kolomyagi were Petrograd Champions in 1916 and came close to the double, losing 2-1 to Sport in the cup final (having scored 27 goals in the 2 previous rounds!)
In 1917 and 1918 Kolomyagi retained the championship. In 1919 the league was abandoned but the cup went ahead, Kolomyagi beating Mercur 7-1 in the final.
In 1920 the championship was decided by a knockout tournament that Kolomyagi won by beating Mercur, a feat they repeated in the regular cup final- a quite remarkable game which went to extra time and produced a final score of 9-2.
The other leading team in the city at this time was Mercur . Known as the merchant club- drawing their patrons and players from small businessmen and the working classes, they played in red and black stripes. Mercur (Mercury) made their debut in 1906. After 2 poor seasons they dropped out of the league and reappeared in 1909 and were champions in 1911.
Indifferent seasons followed, though in 1914 Mercur reached the cup final, they were thrashed 8-2 by Sport.
They won the championship in 1915 and were runners up to Kolomyagi in 1916, 1917 and 1918. In 1917 and 1918 they won the cup, the latter being a 3-1 victory over Kolomyagi . As we have seen Kolomyagi enjoyed revenge in the next 2 seasons, thrashing Mercur 7-1 and 9-2 in successive cup finals and also beating them to the championship.
Mercur enjoyed a further 2 championships (1921,1923)* in the years before Petrograd became Leningrad.
* some sources have Mercur as 1922 champions, other as runners up and winners 'unknown'.
