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 a dependent territory. Whether attainment of independence is different from revolution has long been contested, and has often been debated over the question of violence as a 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. Nation-states have been granted independence without any revolutionary acts.
