History

Before the Spanish 
The land where Colombia now stands has been home to people for more than 20,000 years. The first people had many groups, cultures, and languages. There are many tools, caves, and things of those peoples. In Colombia, the peoples were similar to those of Asia, because scientists say that the first people came to America from Siberia or southeast Asia more than 50,000 years ago. The peoples of Colombia were called Arawak, Caribe, and Chibcha, but there were many other groups. The most famous were the Muiscas. legend of El Dorado comes from the Muiscas. The king of the Muiscas used to bathe in Lake Guatavita and he used a lot of gold for his bath. The Spanish heard about this, and the people told them that there was a great golden city somewhere. They started to look for El Dorado. The International Airport of Bogotá is called El Dorado International Airport, because the legend was born in Colombia. The descendants of the first peoples of Colombia live integrated with others. Some groups live in the forest, but many live in the countryside and in the cities.

The colony 
The Spanish, led by Christopher Columbus, first came to the Americas in 1492. Columbus saw the coasts of Venezuela, Colombia and Panama and he gave them his own name. But Alonso de Ojeda was the first colonist to explore the area of the Gulf of Darién. After that, the Spanish founded the first European cities on the American continent: Santa Marta in 1525 and Cartagena de Indias in 1533. It was from Colombia that the Spanish conquered the Incas of Peru.

Spain would enslave the indigenous peoples who were already living there, but they also used the port they built at Cartagena to bring many black slaves from Africa into the area. The Spanish captured many, many people from Africa and forced them to work on plantations and ranches, in mines, and as personal servants.

While this was happening, they founded the city of Popayán in 1536 and they conquered the Confederation of the Muiscas. In Bacatá, the capital of the Muiscas, the Spanish founded the city of Santa Fe in 1538. In 1550 the Spanish declared the territory as a colony and its capital was Santa Fe de Bogotá, but in the first decades it depended on Peru. Soon after, it was declared a Viceroyalty.

Independence 
On November 11, 1810, the city of Cartagena de Indias declared its independence from Spain. The whole region would fight a war to become independent, led by people like Antonio Nariño and Simón Bolívar. Nariño was one of the most important leaders in the war for the independence of Colombia. He was a politician, journalist and soldier. Bolivar was another important leader, and he was a president and a colonel. Bolivar had promised Alexandre Pétion, the president of Haiti, that he would abolish slavery during his independence war. But he only agreed because he was afraid the slaves would revolt against the slaveowners, like they did in Haiti, and only freed slaves if they agreed to fight in his army. He never freed all the slaves, and slavery was not abolished in Colombia until 1851.

Geography
The geography of Colombia has six main natural regions. Each has its own unique characteristics. The Andes mountain region shares borders with Ecuador and Venezuela. The Pacific Coast region shares borders with Panama and Ecuador. The Caribbean coastal region shares borders with Venezuela and Panama. The Llanos (plains) shares a border with Venezuela. The Amazon Rainforest region shares a border with Venezuela, Brazil, Peru and Ecuador. The insular region includes all the islands of the country.

The main rivers of Colombia are Magdalena, Cauca, Guaviare, Atrato, Meta, Putumayo and Caquetá. Colombia has four main drainage systems: the Pacific drain, the Caribbean drain, the Orinoco Basin and the Amazon Basin.

Most of the population lives in the Andes region. But the plains make over half the land. Only about 6% of the people live in the plains. The Sierra Nevada de Santa Marta mountain range includes the country's tallest peaks (Pico Cristóbal Colón and Pico Simón Bolívar).

Climate 

Colombia's temperature changes with the altitude, and the temperature is different by region. The regions around the Andes are colder than the coast, which is lower.

Because of the many altitudes, Colombia has many different fruits, vegetables and kinds of animals. It has many valleys, beaches, plains, mountains and forests like the Amazon rainforest.

The top of some of the mountains in Colombia are so cold that people can ski over the equator. The lower mountains have warmer climates. The sea shores are cooled by ocean breezes. At sea level near the equator it is hot.

Rivers are important as waterways in the land for shipping things. One of the most important rivers in Colombia is the Magdalena-Cauca. The Magdelena River divides the eastern and center mountains. It makes a fertile valley. The Cauca River divides the center mountain range and the western ridge, making another great valley. The Cauca is really a part of the Magdalena. However, the two do not meet until a few miles before the Magdalena goes into the Caribbean Sea.

Biodiversity 
Colombia is a megadiverse country. This means the country is home to a majority of Earth's species. There are also a high number of endemic species.

Colombia has 1,900 species of bird, more than any other country. There are about 2,000 species of marine fish. It is the second most diverse country in freshwater fish. As for plants, the country has between 40,000 and 45,000 species. Colombia is second in the number of amphibian species and is the third most diverse country in reptiles. There are about 2,900 species of mollusks and about 300,000 species of invertebrates.

Politics 
In May 2006, President Álvaro Uribe was re-elected. His term lasted until 2010. Uribe was the first President in Colombia to win a second election in over 100 years.

In August 2010, Juan Manuel Santos became Colombia's president. Santos won the election on June 20 by a landslide. He promised to "preside over a government of national unity that will bring social prosperity for all Colombians"

Eight years later, conservative Senator Iván Duque Márquez was elected president and soon became the nation's latest president. He won the election by 2 million votes against his rival liberal Senator Gustavo Petro.

Departments
Colombia is divided into 32 departments and one capital district. The capital district is treated as a department. Departments are divided into municipalities. Municipalities are divided into corregimientos. Each department has a local government with a governor and assembly directly elected to four-year terms. Each municipality is headed by a mayor and council. Each corregimiento by an elected corregidor, or local leader.

Demographics 
The population of Colombia was approximately 47 million as of 2016. The ethnic groups of the population are:
 48% Mestizo
 23% Mulatto
 20% White
 6% Black
 2% Amerindian

Security 
There are several guerilla groups in Colombia, the FARC being the most powerful, a guerilla group responsible for kidnappings, murders, attacks, and drug-dealing. Drug dealing is a problem the government has been trying to fight. This creates violence in the cities. With Operation: Jaque, Ingrid Betancourt, three Americans, and 11 soldiers were rescued from the FARC.

Transport 
Most parts of Colombia are modern and the country has many roads. All major Colombian cities have airports and there are many ports on both oceans (Pacific and Atlantic). Because Colombia is a huge country and there are many mountains, airports are very important in the country. There are some regions like the Amazon Forest and Dariend, where the most important way of transportation is by the rivers.
 Roads: The Pan American Highway in South America begins in Colombia. You can go as far as Tierra de Fuego in Chile using that road. Most of the Colombian cities are connected by road in Colombia. The most important roads are the Bogotá-Medellín Highway, the Bogotá-Cali Highway, the Bogotá-Cucuta Highway, the Bogotá-Barranquilla Highway and many others connecting big cities like Medellín, Cali, Barranquilla and Cartagena de Indias with other important centers. You can go by road from Bogotá to Caracas, Venezuela and Quito, Ecuador. The major cities have bus stations.
 Airports: They are very important in Colombia and all the main cities have their own airports. The El Dorado International Airport in Bogotá is the most important. The Palmaseca International Airport in Cali is the second most important. Other important airports are the ones of Medellín, Barranquilla, San Andrés and Cartagena de Indias. The Colombian airports have international connections with most of the South American capitals, North America and Europe. The main Colombian airline is Avianca and it is the second oldest world airline and one of the most important in Latin America.
 Ports: Colombia has coasts on both oceans - Atlantic and Pacific - and it is one of the first world water reserve because it has many rivers and lakes. The longest rivers are the Amazon, Magdalena, Cauca, and the Atrato. The main ports on the Atlantic coast are Barranquilla, which was the first Colombian port, Cartagena de Indias and Santa Marta. There are other ones like Rioacha and Turbo. The ports on the Pacific coast are Buenaventura and Tumaco. The port of the San Andres Island is also one of the most important for the country in the Caribbean and Antillean Sea. The city of Leticia is a very important river port on the Amazon river.
 Train: The National Train was very important to Colombia during the 20th century, but it was forgotten when roads and airports were developed. Today the railways in Colombia are used more for tour visits, and they are not modern.
 Transportation in the cities: The major Colombian cities have a very good system of transportation. There are public buses that connect the suburbs to the center of the cities. There are many taxi companies in Colombia. There are also very modern urban transports in the main cities like Transmilenio in Bogotá, the Metro in Medellín, and similar proposals in Cali, Barranquilla, Cartagena de Indias and many others that are being developed.
