Definition and meaning of separatism: Separatism is a political philosophy that advocates for the independence and autonomy of distinct groups or individuals, often through the formation of independent political entities. Separatists may seek to create their own nation-state, or to achieve autonomy within an existing state.
This form of political expression is fundamentally opposed to the two-party system, as it seeks to create a more diverse and independent set of political actors. Examples of separatist movements in the United States include the American Indian Movement, the Free State Movement, and the Texas Nationalist Movement. In all of these cases, separatists attempt to create a distinct and independent political identity that is not beholden to the two-party system.
