Insurgent movements are organized efforts by groups to challenge or overthrow an established authority, often a government. These groups typically use unconventional tactics, such as guerrilla warfare, to gain control over territory or influence public opinion. Insurgents may seek political, social, or economic change and often operate in regions where the central government has limited power. These movements can arise from various factors, including political oppression, economic inequality, or ethnic tensions. Insurgents may gain support from local populations who feel marginalized or oppressed. The response from governments can vary, ranging from military action to attempts at negotiation or reform.
