One of the oldest clubs in the
Valencian Community, Eldense enrolled in the
Valencian Football Federation in 1924, and started competing in
Tercera División 19 years later. It first appeared in
Segunda División in the
1956–57 season, narrowly avoiding relegation after finishing in 16th position; the first spell in that tier lasted three years, in a total of five at the professional level.
Match fixing allegations On 4 April 2017, Eldense coach Filippo Vito di Pierro and
general manager Nobile Capuani were arrested by Spanish authorities on charges of corruption. The detentions occurred after club president David Aguilar made complaints of
match fixing following a 0–12 loss to
Barcelona B, whilst Eldense player Cheikh Saad said that he had seen Aguilar arguing with di Pierro at half-time of the match, calling the latter a "scoundrel"; subsequently, the former asked
La Liga president
Javier Tebas to investigate those allegations. Eldense temporarily suspended all sporting activities, also ending its contract with the Italian investment group represented by Capuani. They also released 12 players, with five people being arrested in connection with the events.
Three consecutive promotions Eldense spent four years in
Tercera División and were promoted to the new fourth level
