An insurrection is a violent and organised attempt to challenge or overthrow a lawful government or authority. It differs from protests or riots because it involves clear political intent and the use of force against state institutions. In the UK, actions resembling insurrection are treated as serious crimes under laws related to national security, terrorism, and public order. The term has become more visible in global news due to political unrest and attacks on democratic systems. Understanding what insurrection means helps citizens distinguish lawful dissent from actions that threaten democracy and the rule of law.
