Lublinianka is the oldest sports organization in the city of Lublin, and one of the oldest in the region. It continues the traditions of pre-war Wojskowy Klub Sportowy (Military Sports Club) Unia Lublin. The origins of Lublinianka date back to 1921. At that time, it had two departments: football, and track and field. In 1923, the organization split into WKS Lublin and KS Lublinianka, to be reunited in 1927 as WKS Unia.
