Kerala United

Founded in 1976 as Quartz Football Club in Kozhikode, Kerala and since has been growing up step by step from district to state to national level. The Quartz Academy was incorporated in 2009. In December 2011, they were officially certified by the All India Football Federation to participate in the I-League 2nd Division. For the first time in 2012 I-League 2nd Division, Quartz FC participated but failed to make an impression. They only got one point in the group stage thereby failing to get promotion.

In 2012–13 season, Quartz FC signed I-League players like Rino Anto, Sabas Saleel, K. Noushad, Manoj Manoharan, Sherin Sam, Kamardeep Singh, Suji Kumar, J. Prasad, P.M. Britto, Salil Usman and Ajmaluddin. Club also signed the top-scorer and player of the tournament at the 2012 Santosh Trophy V.V. Farhad. They appointed Assistant coach Bino George of Chirag United Club Kerala. Later withdrew from the 2013 I-League 2nd Division due to financial instability.

Club managed to win Kozhikode District League back to back in 2011 and 2012. Later in 2013–14, Quartz played with their academy side in the very first edition of Kerala Premier League. After making a late entry in 2017–18 Kerala Premier League season, the club finished as runners-up after losing to Gokulam Kerala in final. They had withdrawn from two editions of Kerala Premier League (2016–17, 2018–19) due to financial issues.

In November 2020, English Premier League Club Sheffield United have taken over Calicut Quartz and rebranded it as Kerala United FC. United World Group, the umbrella firm holding Sheffield, said in a statement that it envisages to make Kerala United a competitive, community-focused football club playing at the highest level possible in Indian football.

P. Haridas, who owned Calicut Quartz FC, is also the president of the Kozhikode District Football Association (KDFA), said a Premier League club coming to the state will bring major changes to Kerala football. Company director Akshay Das said: "We're looking for an overall development in the state, especially in Malabar."

As Kerala United, they participated in the 2020–21 Kerala Premier League and qualified for the knockout stages after finishing second in the Group-B with 12 points. In the semi-finals, regular time couldn't separate Gokulam Kerala and Kerala United, match ending goalless. They lost 4–2 on penalties at the Thrissur Municipal Corporation Stadium. In that season, they participated in Independence Day Cup in Assam and finished as runners-up, losing to Assam State Electricity Board SC by 4–3 in penalties. In October 2022, Nigerian-born naturalized Indian manager Saheed Ramon was appointed head coach. In 2023, they participated in Stafford Challenge Cup in Bangalore. Kerala United won their first ever Kerala Premier League title in 2022–23, defeating Gokulam Kerala B in final. In August 2023, Kerala United gained I-League 3 spot, ahead of the beginning of its inaugural season. In that tournament, the club finished in fourth place in final round play-off, missed the opportunity of qualifying to I-League 2.
