The Rise of the IncaThe Inca began their progression, extending their territories, and calling themselves Inca around the mid-1300's to 1400's.
Topa Inca Became the Tenth Inca RulerTopa Inca was responsible for the growing size of the Inca empire because he continued his Pachacuti's legacy of military conquest.
Huayna Capac and Millions of Incas Caught FeverSpanish conquistadors made landfall in Inca territory, bringing new diseases with them that killed and weakened the Inca greatly because Huayna Capac and his heir died in the outbreak and caused the Incas to start a civil war between Huayna Capac's sons who survived.
Atahualapa is the New Inca RulerAtahualapa won the civil war against his brother Huascar, and he came across European invaders who outmatched them with their horses and guns. The Spanish took Ataualapa captive, and he died a year after.
The Fall of the IncaThe remaining forces who survived the civil war and fever of the Inca had fled from their old capital Cuzco, to their new one, Vilcabamba. They resisted the conquistadors control for 40 years or so before the Spanish annihilated them completely.
