Blood Law, in some traditional Native American communities, is the severe, usually capital punishment of certain serious crimes.
The responsibility for delivering this justice has traditionally fallen to the family or clan of the victim, usually a male relative.
Justice under Blood Law would be considered revenge killing or summary murder, and also could be an additional aggravating circumstance requiring the death penalty for the crime.
Historically, a "cursory survey of the ethnohistorical literature indicates that death was the standard punishment [for witchcraft] among Native American societies,"[1] including the Cherokee, Chickasaw, Creek, Delaware, Hopi, Miami, Natchez, Navajo and Seneca.
[1][2] In 1824 the western Cherokee passed new laws "forbidding the wanton killing of suspected witches".
