The Incas
Though the Inca's had no actual written history most of what we know about their culture actually comes from archeological finds and Spanish accounts. The Inca empire had a short life of about 100 years and it stretched about 2,500 miles. The Inca's used gifts as well as spears to demonstrate power to potential subjects. They were very willing to fight for their land and homes. When the Spanish conquered the Inca in 1532, they were only a small ethnic group based in Cuzco, and they ruled more than 12 million from 100 different cultures and speaking at least 20 languages. For their time period they were a pretty good and advanced society.
