 After the rule of Pachacuti, when an Inca died, his title went to one son and his property was given to a corporation controlled by his other relatives (split inheritance).Each title holder had to build a new house and add new lands to the empire, in order to own land for his family to keep after his death.According to Inca legend, the city was rebuilt by Sapa Inca Pachacuti, the man who transformed the Kingdom of Cuzco from a sleepy city-state into the vast empire of "Tawantinsuyu".
