Rebellion, uprising, or insurrection is a refusal of obedience or order. It may, therefore, be seen as encompassing a range of behaviours aimed at destroying or taking over the position of an established authority such as a government, governor, president, political leader, or person in charge. On the one hand the forms of behaviour can include non-violent methods such as the (overlapping but not quite identical) phenomena of civil disobedience, civil resistance and non-violent resistance. On the other hand it may encompass violent campaigns. Those who participate in rebellions, especially if they are armed rebellions, are known as "REBELS".
