Rebellion is an uprising that resists and is organized against one's government. A rebel is a person who engages in a rebellion. A rebel group is a consciously coordinated group that seeks to gain political control over an entire state or a portion of a state. A rebellion is often caused by political, religious, or social grievances that originate from a perceived inequality or marginalization. Rebellion comes from Latin re and bellum, and in Lockian philosophy refers to the responsibility of the people to overthrow unjust government.
