Answer:
Human sacrifice
Explanation:
Among the Aztecs, the priests demanded HUMAN SACRIFICE in exchange for promising to bring fertility to the people and the land.
Before the arrival of the Spanish colonial master in modern-day Mexico, the Aztecs' priests who are the custodians of the religious system among the tribe, promised fertility of the people and the Aztec land but mandated the use of human sacrifices, involving several men and women from invaded and imprisoned tribes.
