Tawantinsuyu (also known as the Inca empire) came into existence around 1200 when its capital Cuzco was founded. Undisturbed by the events in the Old World, its history stayed the same as in OTL even centuries after the POD. In 1493, Huayna Capac I became the Inca (ruler) of Tawantinsuyu. He didn't die in 1527, however, since there were no European diseases. One year later, in 1528, his son Huascar Capac was caught conspiring against his brother, the heir of Huayna Capac, named Ninan Cuyochi. Huayna Capac died in 1532, Ninan Cuyochi became new Inca.
