Human sacrifice is the act of killing one or more human beings, usually as an offering to a deity, as part of a religious ritual. Human sacrifice has been practiced in various cultures throughout history. Victims were typically ritually killed in a manner that was supposed to please or appease gods, spirits or the deceased, for example as a propitiatory offering, or as a retainer sacrifice when the King's servants are killed in order for them to continue to serve their master in the next life.
