As Ceres (2012–2020) Early years The club was founded by Leo Rey Yanson in 2012 as Ceres–La Salle, with the cooperation of the
University of St. La Salle of
Bacolod. The club was initially composed of college and some Korean players, becoming primarily led by Philippines national team players. A notable early victory was at the inaugural Negros Men's Open Football Championships in January 2012, an 11–0 win against Bacolod United in the final. United City's first national tournament was the
2012–13 PFF National Men's Club Championship. United City won the championship trophy with a 1–0 victory against
Pasargad in the final. En route to the championship, they won matches against
Stallion,
Global and
Kaya.
United Football League After their victory in the PFF championship, Ceres expressed an intention to join the United Football League (UFL, the top-tier football league in the Philippines at that time). They were not able to play in the 2013 UFL season, however, and joined the league for the
2013 UFL Cup. Ceres debuted in the UFL in the
2014 season in Division 2. The club dominated the division, and was promoted to Division 1 the following season. Ceres were considered serious contenders for the
2015 UFL Division 1 title in their first year, and clinched the championship with several regular-season games to play. They were unable to replicate their success in the 2016 season, and finished second.
First three seasons in the Philippines Football League When the
Philippines Football League supplanted the UFL as the Philippines' top-tier football league, Ceres was among the pioneer clubs of the 2017 inaugural season. Ceres renamed themselves the
Ceres–Negros, designating the
Panaad Stadium in
Bacolod as their home venue. Ceres-Negros won the championship in 2017, 2018 and 2019, and the
2019 Copa Paulino Alcantara title. Issues at
Vallacar Transit affected Ceres–Negros operations during the 2019 season, when the team's status was uncertain due to a Yanson family dispute about Vallacar's management. Although Ceres chairman Leo Rey Yanson lost control of Vallacar after four of his siblings staged a
boardroom coup in July, he regained control of the company in August. Despite the turmoil, Ceres clinched the league title.
As United City (2020–2023) Amidst the
COVID-19 pandemic and after the 2020 PFL season was postponed, rumors of Ceres–Negros' departure from the league (or disbanding) have circulated. In July 2020, Ceres-Negros announced that club owner and chairman Leo Rey Yanson would step down and the club would negotiate with potential investors. Emirati-Philippine sports marketing firm MMC Sportz Asia was announced as the negotiator on behalf of the new group of owners of Ceres–Negros, and renamed the club as
United City. The new owners said that the core of the original club (16 of its 21 players) would remain. MMC Sportz Asia had been involved in Philippine football as appointed marketing arm of
Global F.C. in 2019, but terminated their agreement during the season due to non payment by the club. United City's, (owned by United City Football Company Inc.) new management re-signed Ceres' former players, intending to retain the core of its previous owner. They include team captain
Stephan Schröck, who was appointed a player-coach. They went on to clinch the league title of the shortened
2020 season which was held in a
bubble due to the pandemic. The league title was their first as United City, and their fourth overall.
AFC Champions League debut United City are also the first Filipino Club to qualify in the
AFC Champions League group stage. On 8 July 2021, the club beat Chinese side,
Beijing Guoan to become the first-ever Filipino club to win an AFC Champions League group stage match. In June 2021, in a lead up to the
2021 season, United City announced that it has adopted
New Clark City in
Capas, Tarlac as its home locality. It also has entered a partnership with the local government of
Pampanga. The club with intentions to have its home stadium also announced that it would be temporarily using the
New Clark City Stadium as its home venue. It also said that it would be changing its name to United Clark after the 2021 season however, the name change did not happen as planned. United City was not able to play in their home venue either for the 2021 season since most games were still held at the PFF National Training Center. They are finally set to play their first home game at the
NCC Athletics Stadium on October 22, 2022, as part of the
2022–23 PFL season.
Withdrawal from the Philippines Football League Following the conclusion of the first half of the
2022–23 season, United City released its players and staff. The PFL and the PFF would confirm the withdrawal of the club from the league in February 2023. This is due to the financial issues arising from the club's deal with investor Riau Capital Live (RCL) which is based in Singapore. The RCL entered into a major agreement in United City in mid-2021 but later defaulted in October 2022. The non-fulfillment of RCL's final settlement with United City led to the withdrawal of the club while the results of a legal dispute is pending.
Return to the Philippines Football League United City announced its return to the PFL for the
2024 season, a hybrid tournament that showcases professional and amateur teams. However, they withdrew again the following season reportedly due to financial issues. ==Crest and colors==
