Archaeological research, pioneered by Charles Thurstan Shaw has shown that people were already living in south-eastern Nigeria (specifically Igbo Ukwu, Nsukka, Afikpo and Ugwuele) 100,000 years ago. Excavations in Ugwuele, Afikpo and Nsukka show evidence of long habitations as early as 6,000 BC. However, by 9th Century AD, it seemed clear that the Igbos had settled in Igboland. Shaw's excavations at Igbo-Ukwu, Nigeria revealed a 9th-century indigenous culture that created highly sophisticated work in bronze metalworking, independent of any Arab or European influence and centuries before other sites that were better known at the time of discovery.
