Some theories claim the earliest human habitation of South America to be as early as 43,000 BC, but the current scholarly consensus among archaeologists is that human habitation in South America only dates back to around 15,000 BC at the earliest. Anthropologist
Tom Dillehay dates the earliest hunter-gatherer cultures on the continent at almost 10,000 BC, during the late
Pleistocene and early
Holocene periods. According to his evidence based on rock shelters, Colombia's first human inhabitants were probably concentrated along the Caribbean coast and on the Andean highland slopes. belonged to several hundred tribes, and largely spoke mutually unintelligible dialects. and is considered the world's largest

Ciudad Perdida is a major settlement believed to have been founded around 800 CE. It consists of a series of 169
terraces carved into the mountainside, a net of tiled roads and several small circular
plazas. The entrance can only be accessed by a climb up some 1,200 stone steps through dense jungle.
Pre-Columbian history . The complexity of the Indigenous peoples' social organization and technology varied tremendously, from stratified agricultural chiefdoms to tropical farm villages and nomadic hunting and food-gathering groups. At the end of the colonial period, the native population still constituted about half of the total population. In the agricultural chiefdoms of the highlands, the Spaniards successfully imposed institutions designed to ensure their control of the Amerindians and thereby the use of their labor. The colonists had organized political and religious administration by the end of the sixteenth century, and they had begun attempts to religiously convert the Amerindians to Christianity, specifically Roman Catholicism. The most important institution that regulated the lives and welfare of the highland Amerindians was the
resguardo, a reservation system of communal landholdings. Under this system, Amerindians were allowed to use the land but could not sell it. Similar in some respects to the
Native American reservation system of the United States, the resguardo has lasted with some changes even to the present and has been an enduring link between the government and the remaining highland tribes. As land pressures increased, however, encroachment of white or
mestizo settlers onto resguardo lands accelerated, often without opposition from the government. The government generally had not attempted to legislate in the past in matters affecting the forest Amerindians. During the colonial period,
Roman Catholic missions were granted jurisdiction over the lowland tribes. With the financial support of the government, a series of agreements with the
Holy See from 1887 to 1953 entrusted the
evangelization and education of these Amerindians to the missions, which worked together with government agencies. Division of the resguardos stopped in 1958, and a new program of community development began to try to bring the Amerindians more fully into the national society. The struggle of the Indigenous people on these lands to protect their holdings from neighboring landlords and to preserve their traditions continued into the late 20th century, when the
1991 constitution incorporated many of the Amerindian demands. New resguardos have been created, and others have been reconstituted, among forest tribes as well as highland communities. The 1991 constitution opened special political and social arenas for Indigenous and other minority groups. For example, it allowed for creation of a special commission to design a law recognizing the
black communities occupying unsettled lands in the riverine areas of the Pacific Coast. Article 171 provides special
Senate representation for Amerindians and other ethnic groups, while Article 176 provides special representation in the
Chamber of Representatives: two seats "for the black communities, one for Indian communities, one for political minorities, and one for Colombians residing abroad". Article 356 guarantees Amerindian territorial and cultural rights, and several laws and decrees have been enacted protecting them. Article 356 refers somewhat vaguely to both "Indigenous territorial entities" and Indigenous
resguardos. By 1991 the country's 587 resguardos contained 800,271 people, including 60,503 families. The general regional distribution of these resguardos was as follows:
Amazonia, 88;
llanos, 106;
Caribbean lowlands, 31;
Andean highlands, 104; and
Pacific lowlands, 258. They totaled , or about 24 percent of the national territory. Colombia today may have as many as 710 resguardos in 27 of the 32 departments. ==Indigenous political organization==
