The former political prisoners in Kosovo during the Yugoslav period were mostly charged for irredentist and nationalist activities, and considered internal enemies of Yugoslavia. They were identified as Ilegalja, a blanket term for the underground groups organised in threes. The movement still remains obscure due to their form of activism that acted in secret. The political legacy of Ilegalja is discussed within different historical contexts. Contradicting narratives about this movement calls for new ways of mediating this difficult-to-approach heritage.
