Mlada Boleslav

The first registered football club in Mladá Boleslav and the official predecessor of FK Mladá Boleslav was Studentská XI. The club then transformed itno S.K. Mladá Boleslav and then to Mladoboleslavský SK, officially founded in 1910.

In 1905, a team called SK Aston Villa Mladá Boleslav, referring to the English club Aston Villa F.C., was founded in Mladá Boleslav. In 1919, SK Aston Villa Mladá Boleslav has registered for league competitions, playing home games at the Astonka pitch near Havlíčkova Street. In the same year, the third club in the city – Slavoj Mladá Boleslav was founded. In 1934, new Astonka pitch was opened in Čechova Street.

In 1942 and 1944 respectively, Mladoboleslavský SK and Aston Villa did not take their chances to make it to the top Czechoslovak competition from the final stage of the qualification. The derby between the clubs in 1942 was watched by 8,000 spectators, which remains a record to this day.

In 1948–1949, as a result of the advent of the communist regime in 1948, all three Mladá Boleslav clubs were gradually merged under the club "Závodní sokolská jednota Automobilové závody národní podnik Mladá Boleslav" (ZSJ AZNP Mladá Boleslav), referring by its name to the patronage of the Sokol movement and Škoda Auto factory, which was then called Automobilové závody národní podnik ("Automobile Works national enterprise"). Mladá Boleslav played in the second tier in 1952–1992 with the exception in 1959, when the club played in the third tier. In that era, the name was changed two times (TJ Spartak Mladá Boleslav from 1950, TJ Auto Škoda Mladá Boleslav from 1966). In 1983, 1984 and 1986, the club finished on third place.

In 1965, the new stadium was opened. However, the old pitch, which is still called Astonka, still exists today and the youth teams of FK Mladá Boleslav play matches there.

As a result of Škoda Auto's difficult economic situation after the Velvet Revolution in 1989, the company's support for sports clubs was reduced, leading to relegation of FK Mladá Boleslav to the third tier in 1992–93 and to the fourth tier in 1994–95. During these years, the club was a farm for SK Slavia Prague and Bohemians 1905. In the following two seasons, FK Mladá Boleslav again made it to the second league.

In 2001, the club's most successful era began when the club was bought by the local construction company Gema and the company's co-owner Josef Dufek became the club's president. The new owners subsequently transformed the club into a joint-stock company, renewed cooperation with Škoda Auto as the club's main sponsor, started to cooperate with the city of Mladá Boleslav, acquired other business partners from the region, and renovated the stadium. In the summer of 2002, Josef Dufek publicly announced a five-year plan during which the second-league club was to become a participant in European cups.

The club was promoted to the Czech First League for the first time in its history in the 2003–04 season. In their first top-flight season fought, the club against relegation, eventually finishing in the 14th place. The club's greatest success was achieved in the 2005–06 season, as they finished runners-up in the Czech First League, earning a place in the qualifying rounds of the UEFA Champions League. The club thus fulfilled its ambitious plan in just four years. They came through their first tie, defeating Vålerenga (3–1 and 2–2), then lost against Galatasaray (2–5 away, 1–1 home), dropping into the UEFA Cup first round. The club went on to achieve a surprising 4–3 aggregate victory over Marseille (1st leg: 0–1, 2nd leg 4–2). The home match against Marseille is considered one of the greatest wins in the club's history. However, the club was eliminated after reaching the group stage, taking just 3 points from 4 matches (Panathinaikos 0–1, Hapoel Tel Aviv 1–1, Paris Saint-Germain 0–0, Rapid București 1–1).

The following season, the club finished 3rd in the league. The club's Luboš Pecka was the top goalscorer in the league that season. After the season, the coach Dušan Uhrin, Jr. decided to leave the club after leading it since October 2004. The club qualified directly for the first round of the UEFA Cup. Qualification for the group stage was only narrowly secured by beating Palermo 4–2 on penalties after a nail biting 1–1 aggregate scoreline. On the verge of being eliminated with the score reading 1–0 Palermo, (with their goal in the first leg still standing) in the 2nd leg, Tomáš Sedláček scored the winner in the 2nd leg with only seconds to spare. In their group Mladá Boleslav defeated IF Elfsborg 3–1, but again failed to reach the knockout stages of the competition after losing matches against Villarreal 1–2, AEK Athens 0–1 and Fiorentina 1–2. The club subsequently achieved a 7th place league finish in the 2007–08 season, missing out on European cups.

The club's greatest successes in the following years included winning the Czech Cup in the 2010–11 and 2015–16 seasons. In the league, the club was among the wider top teams from 2010 to 2017, finishing on the third place once and on the fourth place several times. These results guaranteed FK Mladá Boleslav a place in the qualifying rounds of European cups, but the club never managed to advance to the group stage during this era.

In 2018–19, the new format of the Czech First League with division into three groups after the regular season was introduced. In that season FK Mladá Boleslav finished 7th, but won the play-offs for participation in the 2019–20 UEFA Europa League qualifying rounds. The top goalscorer of the 2018–19 season was Mladá Boleslav's Nikolay Komlichenko with 29 goals, which became the league record for goals scored in a single season. In January 2020, Komlichenko transferred to FC Dinamo Moscow for a fee of around 3.5 million EUR, a record in the club's history.

In 2018–2023, the club finished in the middle of the league table each time. In the 2023–24 season, the club finished in fifth place and, after a five-year break, made it to the European cups. After the season, David Trunda bought a majority stake (51 %) in the club and became its president, ending the 21-year era of Josef Dufek. The city of Mladá Boleslav owns 34 % of the shares. In 2024–25 UEFA Conference League, FK Mladá Boleslav advanced through three qualifying rounds to the league phase of the competition.
