South America: Sovereign States and Dependent Territories
South America is a vast and diverse continent, ranking fourth in total area and fifth in population globally. Covering approximately 17,840,000 square kilometres (6,890,000 sq mi), it accounts for nearly 3.5% of the Earth's total surface area. As of 2018, the continent's population was estimated to be over 430 million people.
Geographically, the continent is bounded by the Pacific Ocean to the west and the Atlantic Ocean to the north and east. To the northwest lie North America and the Caribbean Sea. The transition between North and South America occurs at the Isthmus of Panama, with most atlases defining the border along the Darién Mountains watershed, known as the Darién Gap, where the Colombia–Panama border is located.

Defining Sovereignty in South America
A sovereign state is defined as a political association that maintains effective sovereignty over a population and makes decisions in the national interest. According to the Montevideo Convention, a state must possess four specific criteria: a permanent population, a defined territory, a government, and the capacity to enter into relations with other states.
The 12 sovereign states of South America are all members of the United Nations and have been members of the Union of South American Nations.
