The centuries between the fall of Huari and the rise of the Inca were marked in Peru by the florescence of several large states along the coast north (Sicán, Chimor) ad smaller ones along the central and south coasts (Chancay, Pachacamac. Ychsma, Ica etc).. Some of these are mentioned in early Spanish accounts taken from native oral histories, others, those of the northern Andes are completely prehistoric.
