Independence is the state or condition of being free from control, influence, or support by an external power or authority. It often refers to a nation, country, or state exercising self-government and sovereignty over its territory without interference from other countries or powers. Independence can be achieved through various means, including peaceful diplomacy, popular movements, referenda, or war. It is celebrated as a significant milestone, often marked by an Independence Day. The term also applies broadly to personal independence, meaning freedom from reliance on others.
