Korona Kielce II

The club was founded in 1973 after the union of two clubs from Kielce – Iskra and SHL. The new club got its first promotion to the Polish 2nd league in 1975. Unfortunately, the team did not play very well and was soon relegated. The next promotion was in 1982. Korona played in the 2nd league until 1990 when it was once again relegated. 1996 brought several changes. Nida Gips from Gacki became the new sponsor and the club's name changed to Miejski Klub Sportowy Sekcja Futbolowa Korona. During the 1998–99 season, Korona again played in the 2nd league but dropped down at the end of the season. In 2000 Korona merged with another club from Kielce – Błękitni Kielce and was renamed to Kielecki Klub Piłkarski Korona.

In 2002, the golden era for Korona had begun. Kolporter became the new sponsor, Krzysztof Klicki the new chairman, and the club's name changed to Kielecki Klub Piłkarski Kolporter Korona. In 2003, the team was again renamed, this time to Sportowa Spólka Akcyjna Kolporter Korona. In 2005 Korona won the 2nd league and for the first time in the club's history was promoted to the Polish premier league.

Korona's first match in the Ekstraklasa was against Cracovia and the final score was 0–0. Korona ended the 2005–06 season fifth in the league table. Prior to the 2006–07 season, at a meeting with supporters, the chairman announced that club would revert to its historical coat of arms. Korona's second season in the Ekstraklasa started off strongly with an away win against Arka Gdynia (3–0). 20 September 2006 was a significant one in Korona's history. After an away victory against Odra Wodzisław Śląski, the club climbed to the top of the league table for the first time in its history although it ended the 2006–07 season in 7th place. Its third and final season in the top division was 2007–08, placing 6th but being relegated for its involvement in match-fixing in the 2003–04 season. In August 2008, Klicki sold the club to the city of Kielce for a nominal fee.

After one year, on 14 July 2009, Korona Kielce was promoted to the Ekstraklasa. In the 2019–20 season, Korona finished in 15th place and were relegated back to I liga. On 29 May 2022 Korona returned to the Ekstraklasa following a 3–2 win over Chrobry Głogów in the promotion play-off final after the winning goal scored in the final minutes of extra time.
