Religion in politics covers various topics related to the effects of religion on politics. Religion has been claimed to be "the source of some of the most remarkable political mobilizations of our times". Various political doctrines have been directly influenced or inspired by religions. Various strands of Political Islam exist, with most of them falling under the umbrella term of Islamism. Graham Fuller has argued for a broader notion of Islamism as a form of identity politics, involving "support for [Muslim] identity, authenticity, broader regionalism, revivalism, [and] revitalization of the community." This frequently may take a socially conservative or reactionary form, as in wahhabism and salafism. Ideologies which espouse Islamic modernism include Islamic socialism and Post-Islamism. Christian political movements range from Christian socialism, Christian communism, and Christian anarchism on the left, to Christian democracy on the centre, to the Christian right. Beyond universalist ideologies, religions have also been involved in nationalist politics. Hindu nationalism exists in the Hindutva movement. Religious Zionism seeks to create a religious Jewish state. The Khalistan movement aims to create a homeland for Sikhs. An extreme form of religious political action is religious terrorism. Islamic terrorism has been evident in the actions of the Islamic State, Boko Haram, the Taliban and Al-Qaeda, all of these organizations practice jihadism. Christian terrorism has been connected to anti-abortion violence and white supremacy, for example in the Christian Identity movement. Saffron terror describes terrorism connected to Hinduism. There has also been cases of Jewish religious terrorism, such as the Cave of the Patriarchs massacre, as well as of Sikh terrorism, such as the bombing of Air India Flight 182. Religious political issues may involve, but are not limited to, those concerning freedom of religion, applications of religious law, and the right to religious education.
