Bosanska Krupa in the context of "Una (Sava)"

The most widely professed religion in Bosnia and Herzegovina is Islam and the second biggest religion is Christianity. Nearly all the Muslims of Bosnia are followers of the Sunni denomination of Islam; the majority of Sunnis follow the Hanafi legal school of thought (fiqh) and Maturidi theological school of thought (kalām). Bosniaks are generally associated with Islam, Croats of Bosnia and Herzegovina with the Catholic Church, and Bosnian Serbs with the Serbian Orthodox Church. The State Constitution of Bosnia and Herzegovina (BiH) and the entity Constitutions of the Federation of Bosnia and Herzegovina and the Republika Srpska provide for freedom of religion, and the Government generally respects this right in ethnically integrated areas or in areas where government officials are of the majority religion; the state-level Law on Religious Freedom also provides comprehensive rights to religious communities. However, local authorities sometimes restricted the right to worship of adherents of religious groups in areas where such persons are in the minority.

Government protection of religious freedom declined, especially during the campaign period prior to the October 2006 national elections, due to selective legal enforcement and the indifference of some government officials. At the end of the period covered by this report, the Government was implementing the State Law on Religious Freedom to protect the rights of religious communities and create a government registry allowing them to establish legal status.

Religious pluralism is an attitude or policy regarding the diversity of religious belief systems co-existing in society. It can indicate one or more of the following:

• Recognizing and tolerating the religious diversity of a society or country, promoting freedom of religion, and defining secularism as neutrality (of the state or non-sectarian institution) on issues of religion as opposed to opposition of religion in the public forum or public square that is open to public expression, and promoting friendly separation of religion and state as opposed to hostile separation or antitheism espoused by other forms of secularism.
• Any of several forms of religious inclusivism. One such worldview holds that one's own religion is not the sole and exclusive source of truth, and thus acknowledges that at least some truths and true values exist in other religions. Another concept is that two or more religions with mutually exclusive truth claims are equally valid; this may be considered a form of either toleration (a concept that arose as a result of the European wars of religion) or moral relativism.
• Perennialism (based on the concept of philosophia perennis) is the understanding that the exclusive claims of different religions turn out, upon closer examination, to be variations of universal truths that have been taught since time immemorial. While some perennialists are universalists who accept religious syncretism, those of the Traditionalist School reject it, and uphold the importance of the historical, "orthodox" faiths.
• Sometimes as a synonym for ecumenism, i.e., the promotion of some level of unity, co-operation, and improved understanding between different religions or different denominations within a single religion.
• As a term for the condition of harmonious co-existence between adherents of different religions or religious denominations.

European Islam, or Euro-Islam, is a hypothesized new branch of Islam that historically originated and developed among the European peoples of the Balkans (primarily Albania, Bosnia and Herzegovina, Kosovo, and European Turkey, but also in Bulgaria, Montenegro, and North Macedonia, countries with sizable Muslim minorities). These communities, alongside those in some republics of Russia, constitute a large population which constitute large populations of European Muslims. Historically significant Muslim populations in Europe include Azerbaijanis, Ashkali and Balkan Egyptians, Balkan Turks, Bosniaks, Böszörmény, Chechens, Circassians, Cretan Turks, Crimean Tatars, Gajals, Gorani, Greek Muslims, Ingush, Khalyzians, Kazakhs, Lipka Tatars, Muslim Albanians, Muslim Romani people, Pomaks, Torbeshi, Turks, Turkish Cypriots, Vallahades, Volga Tatars, Yörüks, and Megleno-Romanians from Notia today living in East Thrace, although the majority are secular.

The terms "European Islam" and "Euro-Islam" were originally introduced at a conference that took place in Birmingham in 1988, presided by Carl E. Olivestam, senior lecturer at Umeå University, and subsequently published in the Swedish handbook Kyrkor och alternativa rörelser ("Churches and Alternative Movements"). "European Islam" defines the ongoing debate on the social integration of Muslim populations in Western European countries such as France, Germany, the United Kingdom, and the Netherlands. There are three Islamic scholars who participate in the debate on "Euro-Islam": Enes Karić, Bassam Tibi, and Tariq Ramadan, who adopted the term in the second half of the 1990s but use it with different meanings. The foremost Western, Non-Muslim scholars of political science and/or Islamic studies involved in the debate on "Euro-Islam" are Jocelyne Cesari, Jørgen S. Nielsen, and Olivier Roy.
