Tupac Inca Yupanqui (literally “noble Inca accountant”) was the tenth Sapa Inca (1471-93 CE) of the Inca Empire, and fifth of the Hanan dynasty. His father was Pachacuti, and his son was Huayna Capac. His father appointed him to head the Inca army in 1463. He extended the realm northward along the Andes through modern Ecuador, and developed a special fondness for the city of Quito, which he rebuilt with architects from Cuzco. Wikipedia
