Rikon was organized for the first time in October 1997 at the Faculty of Arts and Sciences, University of Rijeka. It was being held at the Faculty anually when due to the adaptation of the building, Rikon had to be organized in Dom željezničara in 2002. One year later, in 2003, Rikon was organized at Centar za radno-proizvodne aktivnosti by a now defunt NGO Aurora. Due to technical and organization problems, in 2004 Rikon was skipped.
Next year, in 2005, NGO Udruga "3. zmaj" (The name, which means "the third dragon", is a pun based on the name of the largest Croatian shipyard, "3. Maj") takes upon itself organization of the convention to this day.
