Introduction
Terrorism is one of the most complex and multi-layered crisis areas of the modern era and has left profound impacts on the international system as well as the internal structures of nation-states. Since the second half of the 20th century, ideologically and ethnically based armed organizations have emerged in various geographies, creating security problems and challenging the political architecture, social cohesion, and legal systems of states. In this framework, organizations such as the Irish Republican Army (IRA), Basque Homeland and Liberty (Euskadi Ta Askatasuna, ETA), the Liberation Tigers of Tamil Eelam (LTTE), the Revolutionary Armed Forces of Colombia (FARC) and the Kurdistan Workers’ Party (Partiya Karkerên Kurdistanê, PKK) are among the examples that need to be carefully examined in terms of their terrorist acts, the demands they represent, the forms of attack and their endgame strategies.
This study aims to analyze the historical origins, organizational structures, and eventual end of these five organizations from a comparative perspective. Some of these organizations have evolved into political representation by choosing the path of integration with democratic systems, while others have been dismantled through foreign interventions and military operations. The end of terrorist organizations has been shaped by the approach of states, the involvement of international actors, and the course of social legitimacy.
