Independence is a condition of a nation, country, or state in which its residents and population, or some portion thereof, exercise self-government, and usually sovereignty, over the territory. The opposite of independence is the status of a dependent territory.
Whether the attainment of independence is different from revolution has long been contested, and has often been debated over the question of violence as legitimate means to achieving sovereignty. While some revolutions seek and achieve national independence, others aim only to redistribute power with or without an element of emancipation, such as in democratization within a state, which as such may remain unaltered. The Haitian Revolution, for example, began as a colony-wide slave uprising that was originally content with the pro-abolitionist French Republic, only to turn into a war of independence when Napoleon tried to re-install slavery. In contrast, the American Revolutionary War was intended to achieve independence from the beginning. Causes for a country or province wishing to seek independence are many, but most can be summed up as a feeling of inequality compared to the dominant power. The means can extend from peaceful demonstrations, like in the case of India, to a violent war like in the case of Algeria.
Autonomy refers to a kind of independence which has been granted by an overseeing authority that itself still retains ultimate authority over that territory (see Devolution). A protectorate refers to an autonomous region that depends upon a larger government for its protection as an autonomous region.
