Persecution is the systematic mistreatment of an individual or group by another group. The most common forms are religious persecution, ethnic persecution, and political persecution, though there is naturally some overlap between these terms. The inflicting of suffering, harassment, isolation, imprisonment, fear, or pain are all factors that may establish persecution. Even so, not all suffering will necessarily establish persecution. The suffering experienced by the victim must be sufficiently severe. The threshold level of severity has been a source of much debate.

As part of the Nuremberg Principles, crimes against humanity are part of international law. Principle VI of the Nuremberg Principles states that

The crimes hereinafter set out are punishable as crimes under international law:... (c)Crimes against humanity:

Telford Taylor, who was Counsel for the Prosecution at the Nuremberg Trials wrote "[at] the Nuremberg war crimes trials, the tribunals rebuffed several efforts by the prosecution to bring such 'domestic' atrocities within the scope of international law as 'crimes against humanity'". Several subsequent international treaties incorporate this principle, but some have dropped the restriction "in connection with any crime against peace or any war crime" that is in Nuremberg Principles.
