Persecution is the systematic mistreatment of an individual/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.
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 the for example although only binding on the 60 states that have ratified it, the Rome Statute of the International Criminal Court) includes in Article 7 the definition for crimes against humanity, and clause 7.1 states "For the purpose of this Statute, "crime against humanity" means any of the following acts when committed as part of a widespread or systematic attack directed against any civilian population, with knowledge of the attack: ... (h) Persecution against any identifiable group or collectivity on political, racial, national, ethnic, cultural, religious, gender as defined in paragraph 3, or other grounds that are universally recognized as impermissible under international law, in connection with any act referred to in this paragraph or any crime within the jurisdiction of the Court; ... ".
Not only theorists of secularization (who presume a decline of religiosity in general) would willingly assume that religious persecution is a thing of the past. However, with the rise of fundamentalism and religiously related terrorism, this assumption has become even more controversial. Indeed, in many countries of the world today, religious persecution is a human rights problem.
With the extermination order Mormons have the distinct privilege of being the only Religious group to have a state of the United States legalize the extermination of their religion. The Mormons suffered through tarring and feathering, their lands being taken from them, mob attacks, and the US sending an army to Utah to deal with the "Mormon problem" in the Utah War. A government militia slaughtered Mormons in what is now known as the Haun's Mill massacre. The Founder of the Mormons, Joseph Smith was killed in Carthage, Illinois by a mob of about 200 men. Currently Mormons still appear to have ill will towards them. In the 2008 US presidential race Mitt Romney's capability as president was attacked by mainstream Christians based on his membership in the LDS Church.
Persecution of Muslims is a recurring phenomenon during the history of Islam. Persecution may refer to unwarranted arrest, imprisonment, beating, torture, or execution. It also may refer to the confiscation or destruction of property, or incitement to hate Muslims. Persecution can extend beyond those who perceive themselves as Muslims to include those who are perceived by others as Muslims, or to Muslims which are considered by fellow Muslims as non-Muslims. In India, there are events of persecution of Muslims by Hindu activists. In 1992, the Babri Mosque was demolished by the Sangh Parivar family of organizations on the basis of their controversial assertion that a Hindu temple belonging to a Hindu god existed at the site before the erection of the Mosque. The 2002 Gujarat violence officially led to the death of 1044 people, 754 Muslims and 290 Hindus.Human Rights Watch puts the death toll at higher figures, with 2000 deaths, mostly Muslim.
Historically, this has been due to two causes: the German population were considered, whether factually or not, linked with German nationalist regimes such as those of the Nazis or Kaiser Wilhelm. This was the case in the World War I era persecution of Germans in the United States, and also in Eastern and Central Europe following the end of World War II. While many victims of these persecutions did not, in fact, have any connection to those regimes, cooperation between German minority organisations and Nazi regime did occur, as the example of Selbstschutz shows, which is still used as a pretense of hostilities against those who did not take part in such organisations. After World War II, many such Volksdeutsche were killed or driven from their homes in acts of vengeance, others in ethnic cleansing of territories prior to populating them with citizens of the annexing country. In other cases (e.g. in the case of the formerly large German-speaking populations of Russia, Estonia, or the Transylvanian (Siebenbürgen) German minority in Rumania and the Balkans) such persecution was a crime committed against innocent communities who had played no part in the Third Reich.
