Copenhagen Series

Copenhagen Series for men, unofficially also known as Københavnerserien and often shortened to KS serien and KS Herre, is the highest division for men organised by the regional football association DBU København (DBUK) and one of the fifth-highest divisions overall in the Danish football league system.

The league, deciding the Copenhagen Football Championship was introduced as a tournament exclusively for amateur clubs located in Copenhagen beginning with the 1889–90 season under the auspices of the Danish Football Association (DBU). With the formation of a regional association for the Copenhagen area in 1903, the administration of the league was handed over to the newly founded Københavns Boldspil-Union (KBU). At the time of the league's inception, it was the top flight of the Danish football league system featuring the best teams in the country, but it has since been moved to its current status as the fifth best level in Danish football, after a short period as the sixth best level, and now features lower ranking amateur clubs from the Copenhagen area and Bornholm including the reserve squads of clubs playing at the Danish third league tier or above.
