mutiny

Mutiny is a revolt among a group of people (typically of a military, of a crew, or of a crew of pirates) to oppose, change, or remove superiors or their orders. The term is commonly used for insubordination by members of the military against an officer or superior, but it can also sometimes mean any type of rebellion against any force. Mutiny does not necessarily need to refer to a military force and can describe a political, economic, or power structure in which subordinates defy superiors.
