Tahuantinsuyu was a patchwork of languages, cultures, and peoples. The components of the empire were not all uniformly loyal, nor were the local cultures all fully integrated. The portions of the Chachapoya that had been conquered were almost openly hostile to the Inca, and the Inca nobles rejected an offer of refuge in their kingdom after their troubles with the Spanish. For instance, the Chimú used money in their commerce, while the Inca empire as a whole had an economy based on exchange and taxation of luxury goods and labour (it is said that Inca tax collectors would take the head lice of the lame and old as a symbolic tribute).
