Extremadura Unión Deportiva was founded in 2007,[2] as the existing CF Extremadura club was experiencing serious financial problems, which would lead to its folding three years later.
Extremadura won their fourth-tier group in 2013, qualifying for the Copa del Rey for the first time. There, they lost 2–1 at home to Albacete Balompié in the first round.[4]
One of the stars of Extremadura's promotion was Enric Gallego, who arrived halfway through the season from UE Cornellà, and scored 15 goals in 19 games in his first professional campaign at the age of 32 before leaving for La Liga club SD Huesca in January 2019 for €2 million.[7] After falling into the relegation zone around that point in the season, the club fired Rodri and hired Manuel Mosquera who guided them to safety; the end of the campaign was also marked by the death of veteran winger José Antonio Reyes in a car accident.[8]
In July 2020, Extremadura was relegated back to the third tier after losing by a single goal away to Cádiz CF, amidst problems between the club president and shareholders.[9] The club faced financial difficulties during most of the 2021–22 season, with several players opting to leave during the winter transfer window.[10]
Extremadura changed ownership in January 2022,[11] but as the financial problems were unsolved, the players began a strike in February.[12] On 28 February, after two consecutive no-shows in the competition, the club was expelled from the division;[13]RFEF confirmed the decision on 2 March, with the club being immediately relegated and being unavailable for promotion in the ensuing campaign.[14]
In May 2022, as the club was already in a liquidation process, a new club named CD Extremadura 1924 was founded in the city, with the goal of obtaining Extremadura UD's place in the Segunda División RFEF.[15]
Extremadura UD B was created after integrating San José Promesas in the club in 2016. In its first season, it played with the name of Extremadura San José, before changing to its current name in the next season.
