LKS Lodz

The club was founded in 1908. It was one of the founders of the Ekstraklasa, Poland's top division.

During World War II, two pre-war players of ŁKS, Adam Obrubański and Alojzy Welnitz, were among Poles murdered by the Russians in the large Katyn massacre in April–May 1940.

ŁKS enjoyed greatest success in the 1950s and 1990s, when it reached the podium six times, including winning the championship title in 1958 and 1997–98. It also won the Polish Cup in 1957, and reached the final in 1994.

In March 2010, the city government sold the football team to a private investor, as the city could no longer afford to support the football team, particularly after several seasons in the top level Ekstraklasa, where expenses often exceeded the ticket revenue from the club's small seating-capacity stadium.

In May 2013, at the conclusion of the second-tier 2012–13 I liga season, the private investor declared bankruptcy. The club survived when a partnership between fans and other local investors raised the necessary funds to enter the much more affordable amateur fifth-level IV liga in time for the 2013–14 IV liga season, competing against other local area teams in the Łódź group. The rebuilt club returned to the top division in 2019.

On 28 May 2023, ŁKS secured promotion to Ekstraklasa after a 1–1 draw against Arka Gdynia; this result also confirmed ŁKS as I liga champions. ŁKS suffered a yo-yo year and were relegated to the second division after just one season back in the top flight.
