[1] The term Holy War was coined by the defender from KS Cracovia, Ludwik Gintel.

The earliest extant records of the Holy War originate from the newspaper published on 20 September 1908 informing that the match played at Błonia Park between the two teams resulted in a 1:1 draw.

The first competition in accordance with the 1904 official FIFA standards, took place on 8 May 1913 at the Cracovia stadium in Kraków, with the home team winning over Wisła 2:1.

Despite the fact that the two stadiums are less than a kilometer away, the fans are two bitter rivals against each other, often resulting in fights between them as well as the police.

In the following, all players are listed who were under contract with the first team of both clubs from the first season played in the Polish First League in 1927.
