The Sieraków Sports Club "Warta" was established in the difficult year of 1939 for Poland. The organizer and president of the club at that time was Józef Dyniewicz, a shopkeeper. During the war, for obvious reasons, "Warta" suspended its activity, which it resumed after 1945. In those years, the players still played in the park across the Warta River. Later, the club changed its name to "Spójnia" and operated at the Warta Glassworks in Sieraków. Another organization associating footballers was the Ludowy Klub Morena. From May 1, 1977 to August 31, 1979, it played in the C class, while in the years 1979-1980 in the B class. The club was dissolved for a good few years. It was reactivated in 1990 as the WARTA Sieraków Sports Club, and Włodzimierz Góral became the president. In 1998, the club was taken over by Grzegorz Chojan, who managed it until his death. Later, Adam Brzeziński took over the management of Warta, and thanks to his dedication and commitment, he brought a new quality to the club. During this short period of its activity, the changing rooms were renovated, the main and training pitches were renovated, and most importantly, the club achieved the greatest success in its 68-year history - promotion to the district class, in which, as a newcomer, it took 9th place. On July 16, 2010, Tomasz Dobkowicz died in a tragic accident - a football player and later the Vice-President of the Sierakowski Sports Club "Warta". Tomek is a person we will never forget, he was with us in moments of triumph and defeat. We will definitely miss him. The current president is Zbigniew Sus, who is assisted by secretary Wojciech Maćkowiak and members of the board.
