Genocide is defined as the mass, organized elimination of a racial or ethnic group through killing, causing serious harm, inflicting living conditions to bring about destruction, preventing births, or forcibly transferring children. The UN Genocide Convention of 1948 defines genocide as a crime and lists five punishable acts: genocide, conspiracy to commit genocide, direct and public incitement, attempt, and complicity. Dr. Gregory Stanton of Genocide Watch identified ten stages that often occur in genocides: classification, symbolization, discrimination, dehumanization, organization, polarization, persecution, preparation, extermination, and denial.
