Chimú culture
The Chimú were the residents of Chimor, with its capital at the city of Chan Chan, a large adobe city in the Moche Valley of present-day Trujillo city. The culture arose about 900 AD. The Inca ruler Tupac Inca Yupanqui led a campaign which conquered the Chimú around 1470 AD.
This was just fifty years before the arrival of the Spanish in the region. Consequently, Spanish chroniclers were able to record accounts of Chimú culture from individuals who had lived before the Inca conquest. Similarly, archaeological evidence suggest Chimor grew out of the remnants of Moche culture; early Chimú pottery had some resemblance to that of the Moche. Their ceramics are all black, and their work in precious metals is very detailed and intricate.
The Chimú resided on the north coast of Peru: "It consists of a narrow strip of desert, 20 to 100 miles wide, between the Pacific and the western slopes of the Andes, crossed here and there by short rivers which start in the rainier mountains and provide a series of green and fertile oases." The valley plains are very flat and well-suited to irrigation, which is probably as old as agriculture here. Fishing was also very important and was almost considered as important as agriculture.
