Tsarsko Selo Sofia

In the summer of 2015, the previous chairman of CSKA Sofia Stoyne Manolov established a new academy called Football Academy Tsarsko Selo, with a focus on scouting and developing youth football players born in 2002 to 2010. The club was initially registered and a subsequent men's team in the A RFG Sofia South was established, with former long-time CSKA Sofia captain Todor Yanchev appointed as manager. On November 12, 2015, Manolov announced an academy partnership with Spanish La Liga club Málaga CF. In the end of December 2015, Todor Yanchev took over Sofia 2010, which was bought by Manolov and was merged with Tsarsko Selo to establish a new club called Tsarsko Selo Sofia.

On 28 July 2016 the team was accepted in the newly created Bulgarian Second Professional League. They finished their first match against Botev Galabovo with a draw. In their first match for the Bulgarian Cup they played against Levski Sofia. The match was played on 22 September 2016 at the Lokomotiv Stadium in Sofia and was won by Levski by 2–0. After 2 heavy defeats, Yanchev stepped down from his position as a manager and on 29 October 2016, previous Cherno More Varna head coach Nikola Spasov was announced as the new manager of the team. The team finished their first season in Second League in 5th place.

The good start of the season for Tsarsko Selo was marked not only by the first place in the league after 8 rounds, but with their first win for the Cup, winning the first round against Neftochimic Burgas on 19 September 2017. On 3 January 2018 Nikola Spasov was announced as the new manager of the Kazakhstan Premier League team Kyzylzhar. Shortly the same day Veselin Velikov was announced as the new manager of the club. On 8 May 2018 Velislav Vutsov was announced as the new head coach of the team with Velikov becoming a selectionist.

On 22 April 2019 in a goalless draw against CSKA 1948 the kings secured their first place in Second League and won promotion in the First League for first time in their history, being 18 points ahead from the second and third place five rounds before the end of the season.

Tsarsko Selo's first ever match in the Bulgarian First Division resulted in a 0–2 away loss against the actual champion Ludogorets Razgrad. This was followed by a home 0–0 draw to the other debutant Arda Kardzhali. Tsarsko selo's first win came in the fifth round, when the team managed to beat Botev Plovdiv away with 0–2. Two goals for the win were scored by Dutch winger Rodney Antwi. The first home win came in the seventh round with 2–1 against Beroe Stara Zagora. Tsarsko Selo eventually finished 13th, having to play a playoff match in order to remain in the elite. They were drawn against the second-placed team from the Second League, Septemvri Sofia. In a very close fought game played in Sofia, Tsarsko Selo won 2–0, securing their place in the First League for the next season.

In January 2022 an Italian Private Investment company joined the club leadership. On 21 May 2022, in the last match of the season, Tsarsko Selo were awarded a penalty that could secure them the win. Yusupha Yaffa decided to take the penalty despite Martin Kavdanski being the regular penalty taker. Yaffa was ready to take the penalty when the owner of the team, Stoyne Manolov, entered the pitch and fought with him. He left the pitch and Kavdanski took the penalty, but it was saved. On the next day, Manolov announced that the team won't be participating in the league next season and will end their existence.
