Manifest Destiny was the belief prevalent in the 19th century United States that it was the divine right and duty of the country to expand and spread its democratic ideals across the North American continent. It was the idea that American settlers were destined to conquer and populate the entire continent, from the Atlantic to the Pacific Ocean. This belief fueled expansionist policies and led to the acquisition of territories such as Texas, California, Oregon, and the Southwest through treaties, purchases, and military conquest. The concept of Manifest Destiny played a significant role in shaping American history and the country's territorial growth.
