Founded in 1934, Isla Cristina played in the regional leagues until 1994, when they achieved promotion to Tercera División. In the 1997 play-offs, the club achieved a first-ever promotion to Segunda División B after leading their group.[1]
After an impressive ninth position in the 1997–98 season (which included a 4–4 aggregate victory on away goals over La Liga side Sevilla FC in the 1997–98 Copa del Rey),[1] the club had a disastrous 1998–99 campaign, which ended with just four points in 38 rounds,[2] and a record number of seven managers during the entire season; the record of managers was only surpassed by CD Eldense in 2017.[3]
Shortly after Isla Cristina's relegation, the club folded, and a new club called Isla Cristina FC was founded shortly after.[1]
