Insurgent organizations are groups that seek to challenge or overthrow an established government or authority through various means, often including armed conflict. They typically operate in regions where the government is perceived as weak or illegitimate, and they may gain support from local populations by addressing grievances or providing services. These groups can vary widely in ideology, structure, and goals. Some may be motivated by political, religious, or ethnic factors, while others might focus on social justice or economic issues. Notable examples of insurgent organizations include the Taliban in Afghanistan and the FARC in Colombia.
