The Islamization of Albania occurred as a result of the Ottoman conquest of the region beginning in 1385.. "The Ottomans first invaded Albania in 1385. A second Ottoman force was sent to Albania 1394-96, occupying the country. Given both the Ottoman disposition to tolerate religious diversity among loyal subjects and the generally bellicose traditions of the Albanians, Ottoman authorities adopted a conciliatory policy toward Albanian Christians in the early decades of occupation. Still, although conversion to Islam was not required, a Christian Albanian lord could count on winning favor if he converted. If the Ottomans did not believe that religious reasons could compel a Christian to convert to Islam, they nonetheless looked askance when a Muslim converted (or reconverted) to Christianity. This happened in 1443 when Gjergj Kastrioti (called Skenderbeg), who had been reared as a Muslim in the sultan's palace, abandoned the Islamic faith and publicly reverted to the creed of his forefathers. But this conversion was not merely a public gesture of defiance. It was the first act in a revolutionary drama. For, after changing his religious allegiance, Skenderbeg demanded that Muslim colonists and converts alike embrace Christianity on pain of death, declaring a kind of holy war against the sultan/caliph." The Ottomans through their administration and military brought Islam to Albania.

In the first few centuries of Ottoman rule, the spread of Islam in Albania was slow and mainly intensified during the seventeenth and eighteenth centuries. It was one of the most significant developments in Albanian history as Albanians in Albania went from being a largely Christian (Catholic and Orthodox) population to one that is mainly Sunni Muslim, while retaining significant ethnic Albanian Christian minorities in certain regions. The resulting situation where Sunni Islam was the largest faith in the Albanian ethnolinguistic area, but other faiths were also present in a regional patchwork, played a major influence in shaping the political development of Albania in the late Ottoman period. Apart from religious changes, conversion to Islam also brought about other social and cultural transformations that have shaped and influenced Albanians and Albanian culture.

History

Early Ottoman period

Albanians began converting to Islam when they became part of the Ottoman Empire in the late 14th century. Albania differs from other regions in the Balkans such as Bulgaria and Bosnia in that until the 1500s, Islam remained confined to members of the co-opted aristocracy and sparse military outpost settlements of Yuruks.Zhelyazkova, Antonina. Albanian Identities. Sofia, 2000: International Center for Minority Studies and Intercultural Relations. Page 15-16 In the early 1430s, Ottoman rule was challenged by Albanian feudal lords from northern and central Albania and the Ottomans responded with two military campaigns. The Albanian defeats resulted in the Ottomans awarding much land to timars from Anatolia and a quarter to Albanians from the elite. The first conversions to Islam by some of the Albanian Christian elite allowed them to retain some previous political and economic privileges, and to join the emerging class of timar or estate holders of the sipahis in the new Ottoman system..

Among some of these aristocratic figures were George Kastrioti (Skanderbeg) who while in the service of the Ottomans was a convert to Islam and later reverted to Christianity during the late 15th century during the northern Albanian uprising he initiated. In doing so, he also ordered others who had embraced Islam or were Muslim colonists to convert to Christianity or face death. Skanderbeg received military assistance from the Kingdom of Naples that sent in 1452 Ramon d'Ortafà who was appointed as viceroy of Albania and tasked with maintaining Catholicism among the local population from the spread of Islam.. During the conflicts between Skanderbeg and Ottomans the various battles and raiding pushed Sultan Mehmet II to construct the fortress of Elbasan (1466) in the lowlands to counter resistance coming from the mountain strongholds.. During Skanderbeg's uprising, many of the Muslims and Jews in the Vlorë area were killed and some fled to Italy or Istanbul. In Albania, the important trade center Valona had a large number of Jewish immigrants from the Iberian peninsula... though the subsequent Christian Albanian revolt against the Ottomans, led by Scanderbeg, massacred most of the area's Muslims and Jews and forced the remainder to flee, mostly to Istanbul or Italy. Prior to and after Skanderbeg's death (1468) parts of the Albanian aristocracy migrated to southern Italy with some number of Albanians to escape the Ottoman conquest whose descendants still reside in many villages they settled. Another Albanian uprising against Ottoman rule happened in 1481.

Even long after the fall of Skanderbeg, large regions of the Albanian countryside frequently rebelled against Ottoman rule, often incurring large human costs, including the decimation of whole villages.Zhelyazkova, Antonina, Albanian identities, page 15. In the 1570s, a concerted effort by Ottoman rulers to convert the native population to Islam in order to stop the occurrence of seasonal rebellions began in Elbasan and Reka, and a failed rebellion in 1596 among Catholics in the North preceded a series of heavy punitive measures that induced conversion to Islam.Zhelyazkova, Antonina. Albanian Identities. Pages 15-16, 19. The peak of Islamization in Albania occurred much later than other Islamized or partially Islamized areas: 16th century Ottoman census data showed that sanjaks where Albanians lived remained overwhelmingly Christian with Muslims making up no more than 5% in most areas while during this period Muslims had already risen to large proportions in parts of Bosnia (Bosnia 46%, Herzegovina 43%, urban Sarajevo 100%), Northern Greece (Trikala 17.5%), urban Macedonia (Skopje and Bitola both at 75%) and Eastern Bulgaria (Silistra 72%, Chirmen 88%, Nikopol 22%). Later on, in the 19th century, when the process of Islamization had halted in most of the Balkans it continued to make significant progress in Albania, especially in the South.

In the early period of Ottoman rule, the areas that form contemporary Albania were reorganised into an administrative unit named Sancak-i Arnavid or Sancak-i Arnavud.. During the onset of Ottoman rule only prominent churches with significant symbolic meaning or cultural value of an urban settlement were converted into mosques.. Most early mosques constructed in Albania were mainly built within fortresses for Ottoman garrisons at times by Ottoman Sultans during their military campaigns in the area like Fatih Sultan Mehmet Mosque in Shkodër, the Red Mosque in Berat and others.

As a rule, Ottoman rule largely tolerated Christian subjects but also discriminated against them, making them second-class citizens with higher taxes and various legal restrictions like being unable to take Muslims to court, have horses, have weapons, or have houses overlooking those of Muslims. While the Ottoman authorities were chronically suspicious of Catholicism, they largely allowed the Orthodox church to function unhindered, except during certain periods when the church was suppressed with expulsions of bishops and seizure of property and revenues. During the Ottoman period, most Christians as well as most Muslims employed a degree of syncretism, still practicing various pagan rites; many of these rites are best preserved among mystical orders like the Bektashi Order.Vryonis, Spyros. Religious Changes and Patterns in the Balkans, 14th-16th centuries

Northern Albania

The Ottoman conquest of certain northern cities from the Venetians happened separately to the initial conquest of Albania from local feudal lords. Cities such as Lezhë fell in 1478, Shkodër during 1478–79 and Durrës in 1501 with the bulk of their Christian population fleeing. Over the course of the sixteenth century, the urban populations of these cities became primarily Muslim.. In the north, the spread of Islam was slower due to resistance from the Roman Catholic Church and the mountainous terrain which contributed to the curbing of Muslim influence in the 16th century.. The Ottoman conquest and territorial reorganisation of Albania though affected the Catholic church as ecclesiastical structures were decimated.. In the 16th century, the sanjak of Shkodër was reported as having a Muslim population standing at 4.5% of the total, while Dukagjini (sparsely populated at the time) had 0% and Prizreni had 1.9%.

Catholic Albanian rebellions, often in the context of Ottoman wars with Catholic powers of Venice and Austria in the seventeenth century resulted in severe reprisals against Catholic Albanians who had rebelled which accentuated conversion to Islam. In 1594, the Pope incited a failed rebellion among Catholic Albanians in the North, promising help from Spain. However the assistance did not come, and when the rebellion was crushed in 1596, Ottoman repression and heavy pressures to convert to Islam were implemented to punish the rebels. Steep decreases occurred during the 1630s-1670s where for example the number of Catholics in the diocese of Lezhë declined by 50%, whereas in the diocese of Pult Catholics went from being 20,000 to 4,045 adherents, with most converting to Islam and a few to Orthodoxy.. "Then, in 1644, war broke out between Venice and the Ottoman empire. At the urging of the clergy, many Albanian Catholics sided with Venice. The Ottomans responded with severe repressions, which in turn drove many Catholics to embrace Islam (although a few elected to join the Orthodox Church instead)... Within the span of twenty-two years (1649-71) the number of Catholics in the diocese of Alessio fell by more than 50 percent, while in the diocese of Pulati (1634-71) the number of Catholics declined from more than 20,000 to just 4,045. In general, Albanian insurrections during the Ottoman-Venetian wars of 1644-69 resulted in stiff Ottoman reprisals against Catholics in northern Albania and significantly accelerated Islamization... In general, a pattern emerged. When the, Ottoman empire was attacked by Catholic powers, local Catholics were pressured to convert, and when the attack on the Ottoman empire came from Orthodox Russia, the pressure was on local Orthodox to change faith. In some cases Islamization was only superficial, however, and in the nineteenth century many villages and some entire districts remained "crypto-Catholic" in spite of the adopting the externals of Islamic culture."

During the Great Austro-Turkish War, Albanian Catholic leaders Pjetër Bogdani and Toma Raspasani rallied Kosovo Albanian Catholics and Muslims to the pro-Austrian cause. After the war, when Kosovo did not end up part of the Habsburg empire, harsh reprisals followed. Large numbers of Catholic Albanians fled north where many "died, some of hunger, others of disease" around Budapest. After the flight of Serbs, the Pasha of Ipek (Albanian Peja, Serbian Pec) forced Catholic Albanians in the North to move to the now depopulated plains of Southern Serbia, and forced them to convert to Islam there.Pahumi, Nevila (2007). "The Consolidation of Albanian Nationalism". Page 18: "The pasha of Ipek forcibly removed Catholic inhabitants of northern Albania into the plains of southern Serbia after a failed Serb revolt in 1689 and the flight of many Serbs to the Habsburg Empire. The transferred villagers were forced to convert over to Islam."
