In total, Warta teams, sportsmen and sportswomen won almost 800 medals in Polish championship competitions in different sports disciplines.

Despite these difficulties, in 1914 the second Wielkopolska Championships were held, in which only two teams participated: Warta Poznań and KS Posnania.

But Warta also played various friendly matches against Polish and German teams during the war years, including Fever Kościan (1–3 and 5–5) and DSV Posen (2–2) in 1915, and Stella Gniezno (2–2) in 1916.

[9] In 1917, Warta celebrated its 5th anniversary year by organising a tournament with the participation of the best football teams from Poznań.

Also in 1917, Franciszek Rotnicki became chairman of the club and, during his chairmanship (1917–1924), he laid the structural foundations for Warta's future successes.

It is he, together with a skilfully selected group of associates, who builds solid foundations for the future size of the club in this difficult period.".

[11] During the successful Greater Poland Uprising against German partitioning authorities, many footballers from Poznań volunteered for military service to fight for their country but the restoration of an independent Polish state after 123 years in 1918 also provided new opportunities, as Polish sports clubs were able to function without interference from foreign powers.

Finally, with the Hungarian coach Béla Fűrst in charge, Warta won its first Polish football championship in 1929.

[17] The global economic crisis of 1929 negatively affected Polish sports clubs, including Warta.

[25] Three pre-war players, Marian Spoida, Konrad Ofierzyński and Telesfor Banaszkiewicz, were among Poles murdered by the Soviets in the large Katyn massacre in April–May 1940.

Interest in the final match in Poznań was enormous and the stadium attendance was higher than nominal capacity (over 20 000 spectators).

[29] However, the Stalinism era ended the series of Warta's successes, as regional Communist leadership favoured the local rival Lech Poznań.

Their involvement did not return Warta to its former glory, but it significantly helped to develop the club's logistical base.

Warta's tennis section was particularly known for the individual achievements of Wiesław Gąsiorek, who was Polish men's singles champion 12 times between 1959 and 1970.

In 1989, at the end of the Communist period, Warta and Hipolit Cegielski Poznań works parted ways.

At the beginning of the 1990s, Warta returned to the top tier of the Polish football league system after 43 years for two seasons 1993/94 and 1994/95.

After relegation in 2013 and because of club debts, Warta landed in the fourth tier of the league system where it spent two seasons 2014/2015 and 2015/16.

The situation was so desperate that the football team captain Bartosz Kieliba said: "Several months of player wages are in arrears, there is no certainty whether we will ever play another game, which does not help our work in training or our stance in matches".

In 2020, with experienced players such as Bartosz Kieliba and Łukasz Trałka, Warta surprisingly finished the 2019–20 I liga season in third place.

They contested the 2023–24 season much in the same way as their recent top-flight campaigns, with a below-average budget and limited transfer activity.

[36] On 25 May that year, the last matchday, Warta suffered a 0–3 loss to Jagiellonia Białystok and were jumped in the standings by Korona Kielce following their away win over Lech Poznań.

The club is well known for initiatives to protect the natural environment and its support for social inclusion, and has plans for an eco-friendly new stadium in future.

[38] In May and June 2024, they were in talks to host their home games at the Enea Stadion from the start of the 2024–25 season,[39] before Warta's negotiations with the venue's operator ultimately fell through.
