Sociedad Deportiva Logroñés was founded in 2009, following the serious economic problems which led to the demise of historical Riojan club CD Logroñés. June 4, 2009 is considered the day of the club's founding.[1]
Eventually, as Club Deportivo folded, the new team took its place in the regional leagues, starting in 2009–10. In its debut season Sociedad Deportiva finished as champions, earning promotion to Group 16 in Tercera División.
