In the western Sahel, the rise of settled communities was largely the result of domestication of millet and sorghum. Archaeology points to sizable urban populations in West Africa beginning in the 2nd millennium BCE. Symbiotic trade relations developed before the trans-Saharan trade, in response to the opportunities afforded by north-south diversity in ecosystems across deserts, grasslands, and forests. The agriculturists received salt from the desert nomads. The desert nomads acquired meat and other foods from pastoralists and farmers of the grasslands and from fishermen on the Niger River. The forest dwellers provided furs and meat.[46] Tichit (Dhar Tichitt) and Oualata were prominent among the early urban centers, dated to 2000 BCE, in present day Mauritania. About 500 stone settlements litter the region in the former savannah of the Sahara. Its inhabitants fished and grew millet. It has been found that the Soninke of the Mandé peoples were responsible for constructing such settlements. Around 300 BCE, the region became more desiccated and the settlements began to decline, most likely relocating to Koumbi Saleh. From the type of architecture and pottery, it is believed that Tichit was related to the subsequent Ghana Empire. Old Jenne (Djenne) began to be settled around 300 BCE, producing iron and with sizable population, evidenced in crowded cemeteries. Living structures were made of sun-dried mud. By 250 BCE, Jenne was a large, thriving market town.[47][48] Farther south, in central Nigeria, around 1000 BCE, the Nok culture developed on the Jos Plateau. It was a highly centralized community. The Nok people produced miniature, lifelike representations in terracotta, including human heads, elephants, and other animals. By 500 BCE, they were smelting iron. By 200 CE, the Nok culture had vanished. Be this as it may, based on stylistic similarities with the Nok terracottas, the bronze figurines of the Yoruba kingdom of Ife and the Bini kingdom of Benin are now believed to be continuations of the traditions of the earlier Nokite culture.[49] |
