Tupac Inca Yupanqui Begins Conquests
1457
Pachacuti's son began military campaigns that would extend Inca control into what is now Ecuador and northern Chile. Quechua became the lingua franca of the Andes under his reach. His logistical system of storehouses along the royal road would supply his armies for years, a coordination no contemporary European state matched.
