RedIRIS originated in 1988 when the National Research and Development Plan implemented a special horizontal programme, known as IRIS (Interconexión de los Recursos InformáticoS, i.e. Computing Resources Interconnection), to set up a network interconnecting the universities and research centres' computer resources.
From when it was set up until the end of 1993, IRIS was managed by Fundesco . After 1991, when the promotion and launch phase was considered complete, the IRIS Programme became RedIRIS. Between January 1994 and 2003 RedIRIS was managed by the CSIC (Spanish National Research Council).
