Islam in Turkey in the context of "Fiqh"

Turkey, officially the Republic of Türkiye, is a country mainly located in Anatolia in West Asia, with a relatively small part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Turkey is home to over 85 million people; most are ethnic Turks, while Kurds are the largest ethnic minority. Officially a secular state, Turkey has a Muslim-majority population. Ankara is Turkey's capital and second-largest city. Istanbul is its largest city and economic center. Other major cities include İzmir, Bursa, and Antalya.

First inhabited by modern humans during the Late Paleolithic, present-day Turkey was home to various ancient peoples. The Hattians were assimilated by the Hittites and other Anatolian peoples. Classical Anatolia transitioned into cultural Hellenization after Alexander the Great's conquests, and later Romanization during the Roman and Byzantine eras. The Seljuk Turks began migrating into Anatolia in the 11th century, starting the Turkification process. The Seljuk Sultanate of Rum ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into Turkish principalities. Beginning in 1299, the Ottomans united the principalities and expanded. Mehmed II conquered Constantinople (modern-day Istanbul) in 1453. During the reigns of Selim I and Suleiman the Magnificent, the Ottoman Empire became a global power. From 1789 onwards, the empire saw major changes, reforms, centralization, and rising nationalism while its territory declined.

Christianity in Turkey has a long history, dating back to the early origins of Christianity in Asia Minor and the Middle East during the 1st century AD. In modern times the percentage of Christians in Turkey has declined from 20 to 25% in 1914, to about 2% in 1927, to 0.2–0.4% today. Sources estimate that the Christian population in Turkey ranges between 203,500 and more than 370,000. However, the exact number remains unclear due to the absence of a religious census in the country. The percentage of Christians in Turkey fell mainly as a result of the late Ottoman genocides: the Armenian genocide, Greek genocide, and Assyrian genocide, the population exchange between Greece and Turkey, the emigration of Christians that began in the late 19th century and gained pace in the first quarter of the 20th century, and due to events such as the 1942 Varlık Vergisi tax levied on non-Muslim citizens in Turkey and the 1955 Istanbul pogrom against Greek and Armenian Christians. Exact numbers are difficult to estimate, as many Turkish former Muslim converts to Christianity often hide their Christian faith for fear of familial pressure, religious discrimination, and persecution.

This was due to events which had a significant impact on the country's demographic structure, such as the First World War, the anti-Christian genocides of Greeks, Armenians, and Assyrians perpetrated by Turkish Muslims, and the population exchange between Greece and Turkey, and the emigration of persecuted Christians (such as Assyrians, Greeks, Armenians, etc.) to foreign countries (mostly in Europe and the Americas) that began in the late 19th century and gained pace in the first quarter of the 20th century, especially during World War I. Signed after the First World War, the Treaty of Lausanne explicitly guarantees the security and protection of both Greek and Armenian Orthodox Christian minorities. Their religious institutions are recognized officially by the Republic of Turkey.

Cultural Muslims, also known as nominal Muslims, non-practicing Muslims or non-observing Muslims, are people who identify as Muslim but are not religious. They may variously be non-observing, secular, irreligious, or individuals who still identify with Islam due to belief, sprituality, family backgrounds, personal experiences, ethnic and national heritage, or the social and cultural environment in which they grew up.

Cultural Muslims can be found across the world, but especially in the Balkans, Central Asia, Europe, the Maghreb, various countries in South Asia and West Asia, Russia, Turkey, Singapore, Malaysia, Indonesia and the United States. In several countries and regions, self-reported Muslims practice the religion at low levels, and for some, their "Muslim" identity is associated with cultural or ethnic or national heritage, rather than merely religious faith.

Islam is the second-largest religion in Europe after Christianity. Although the majority of Muslim communities in Western Europe formed as a result of immigration, there are centuries-old indigenous European Muslim communities in the Balkans, Caucasus, Crimea, and Volga region. The term "Muslim Europe" is used to refer to the Muslim-majority countries in the Balkans and the Caucasus (Albania, Azerbaijan, Bosnia and Herzegovina, Kosovo, and Turkey) and parts of countries in Central and Eastern Europe with sizable Muslim minorities (Bulgaria, Montenegro, North Macedonia, and some republics of Russia) that constitute large populations of indigenous European Muslims, although the majority are secular.

Islam expanded into the Caucasus through the Muslim conquest of Persia in the 7th century and entered Southern Europe after the Umayyad conquest of Hispania in the 8th–10th centuries; Muslim political entities existed firmly in what is today Spain, Portugal, Sicily, and Malta during the Middle Ages. The Muslim populations in these territories were either converted to Christianity or expelled by the end of the 15th century by the indigenous Christian rulers (see Reconquista). The Ottoman Empire expanded into Southeastern Europe and consolidated its political power by invading and conquering huge portions of the Serbian and Bulgarian empires, and the remaining territories of the region, including the Albanian and Romanian principalities, and the kingdoms of Bosnia, Croatia, and Hungary between the 14th and 16th centuries. Over the centuries, the Ottoman Empire gradually lost its European territories. Islam was particularly influential in the territories of Albania, Bosnia and Herzegovina, and Kosovo, and has remained the dominant religion in these countries.

Islam is the second largest religion in the Netherlands, after Christianity, and is practised by 6% of the population according to 2023. estimates. The majority of Muslims in the Netherlands belong to the Sunni denomination. Many reside in the country's four major cities: Amsterdam, Rotterdam, The Hague and Utrecht.

The early history of Islam in the Netherlands can be traced back to the 16th century, when a small number of Ottoman merchants began settling in the nation's port cities. As a result, improvised mosques were first built in Amsterdam in the early 17th century. In the ensuing centuries, the Netherlands experienced sporadic Muslim immigration from the Dutch East Indies, during their long history as part of the Dutch overseas possessions. From the dissolution of the Ottoman Empire after the First World War until the independence of Indonesia, the Dutch East Indies contained the world's second largest Muslim population, after British India. However, the number of Muslims in the European territory of the Kingdom of the Netherlands was very low, accounting for less than 0.1% of the population.

Islam is the most popular religion in Bosnia and Herzegovina. It was introduced to the local population in the 15th and 16th centuries as a result of the Ottoman conquest of Bosnia and Herzegovina.

Muslims make the largest religious community in Bosnia and Herzegovina at around 51% of the population.

Islam in Montenegro refers to adherents, communities and religious institutions of Islam in Montenegro. It is the second largest religion in the country, after Christianity. According to the 2011 census, Montenegro's 118,477 Muslims make up 19.11% of the total population. Montenegro's Muslims belong mostly to the Sunni branch. In 2023, Montenegro's 124,668 Muslims made up 19.99% of the total population.

Islam in Georgia (Georgian: ისლამი საქართველოში, romanized: islami sakartveloshi) was introduced in 654 when an army sent by the Third Caliph of Islam, Uthman, conquered Eastern Georgia and established Muslim rule in Tbilisi. Currently, Muslims constitute approximately 9.9% of the Georgian population. According to other sources, Muslims constitute 10-11% of Georgia's population.

In July 2011, the Parliament of Georgia passed new law allowing religious minority groups with "historic ties to Georgia" to register. The draft of the law specifically mentions Islam and four other religious communities.
