Rebel groups are non-state actors that engage in armed conflict against established governments or other opposing forces. These groups typically operate outside of the legal framework and challenge the authority and legitimacy of the ruling regime. Rebel groups can have various motivations for their actions, including political, social, economic, or ethnic grievances. They often use tactics such as guerrilla warfare, terrorism, and propaganda to advance their goals and undermine the authority of the government. Rebel groups can be found in various regions across the world and pose significant challenges to state security and stability. Research on rebel groups often focuses on understanding their origins, motivations, tactics, and impact on conflict dynamics.
