Traditionally, every time an emperor died or resigned, his successor was disinherited from his father inheritance and formed his own lineage royal clan or Panaka, his father's lands, houses and servants were passed to his other children remaining on the previous Panaka. The new Sapa Inca had to obtain land and spoils to bequeath to his own descendants. Each time they subdued a people, they demanded that the defeated leader surrender part of their land to continue in command, and whose people pay tribute in the form of labor (mita) taxes.
