Colombia, formally the Republic of Colombia, is a South American republic with a North American insular area. It is bounded to the north by the Caribbean Sea, to the east by Venezuela, to the southeast by Brazil, to the south by Ecuador and Peru, to the west by the Pacific Ocean, and to the northwest by Panama. Colombia is divided into 32 departments, as well as the Capital District of Bogotá, the country's biggest city. It has a population of 50 million people and an area of 1,141,748 square kilometers (440,831 square miles). Colombia's diverse cultural legacy reflects influences from numerous Amerindian civilizations, European settlement, African slaves, and European and Middle Eastern immigration. Spanish is the official language of the country, however, over 70 other languages are spoken.
Colombia has been inhabited by indigenous peoples such as the Muisca, Quimbaya, and Tairona since at least 12,000 BCE. The Spanish arrived in La Guajira in 1499 and colonized sections of the area by the mid-16th century, creating the New Kingdom of Granada with Santa Fé de Bogotá as its capital. In 1819, what is now Colombia gained independence from the Spanish Empire as the United Provinces of New Granada. Before declaring the Republic of Colombia in 1886, the new country experimented with federalism as the Granadine Confederation (1858) and subsequently the United States of Colombia (1863). Panama seceded in 1903, establishing Colombia's current boundaries. Since the 1960s, the nation has been plagued by an asymmetric low-intensity military war and political violence, both of which erupted in the 1990s. Security, stability, and the rule of law have improved significantly since 2005, as has exceptional economic growth and development.
Colombia is one of the world's seventeen megadiverse nations, with the world's second-highest degree of biodiversity. Its landmass includes the Amazon rainforest, hills, plains, and deserts. It is the only South American nation having coasts and islands on both the Atlantic and Pacific seas.
Colombia is a member of important global and regional organizations such as the United Nations, World Trade Organization, OECD, Organization of American States, Pacific Alliance, and Andean Community. It also serves as a NATO Global Partner. It has the third-largest economy in South America, with macroeconomic stability and strong long-term development prospects.
