The Sao civilisation flourished in Middle Africa from ca. the sixth century BC to as late as the sixteenth century AD. The Sao lived by the Chari River south of Lake Chad in territory that later became part of Cameroon and Chad. They are the earliest people to have left clear traces of their presence in the territory of modern Cameroon. Sometime around the 16th century, conversion to Islam changed the cultural identity of the former Sao. Today, several ethnic groups of northern Cameroon and southern Chad but particularly the Sara, Kotoko claim descent from the civilization of the Sao.
Origins and decline
The Sao civilisation may have begun as early as the sixth century BC, and by the end of the first millennium BC, their presence was well established south of Lake Chad and near the Chari River. The city states of the Sao reached their apex sometime between the ninth and fifteenth centuries AD.
The Sao's demise may have come about due to conquest, Islamization, or both. Traditional tales say that the Sao west of Lake Chad fell to "Yemenites" from the east. These invaders made several unsuccessful attempts to conquer the Sao before finally succeeding by resorting to trickery. If true, the newcomers may have been Arab Bedouin or Sayfuwa raiders coming from the east who moved into the region in the fourteenth century . Although some scholars estimate that the Sao civilization south of Lake Chad lasted until the fourteenth or fifteenth century, the majority opinion is that it ceased to exist as a separate culture sometime in the 16th century subsequently to the expansion of the Bornu Empire. The Kotoko are the inheritors of the former city states of the Sao.
Little is known about the Sao's culture or political organisation: But historians proved that they may have originated from the Nile valley. Historians outlines three major origins for the Sao based on oral tradition and archaeological theories. One theory holds that they were the descendants of the Hyksos who conquered Ancient Egypt. They moved south from the Nile valley into middle Africa in several waves under pressure from invaders. Sao artifacts show that they were skilled workers in bronze, copper, and iron. Finds include bronze sculptures and terra cotta statues of human and animal figures, coins, funerary urns, household utensils, jewelry, highly decorated pottery, and spears. The largest Sao archaeological finds have been made south of Lake Chad.
Ethnic groups in the Lake Chad basin, such as the Buduma, Gamergu, Kanembu, Kotoko, and Musgum claim descent from the Sao. Lebeuf supports this connection and has traced symbolism from Sao art in works by the Guti and Tukuri subgroups of the Logone-Birni people. Oral histories add further details about the people: The Sao were made up of several patrilineal clans who were united into a single polity with one language, race, and religion. In these narratives, the Sao are presented as giants and mighty warriors who fought and conquered their neighbors.
