White Slavery in the Ottoman Empire:
White slavery (also white slave trade or white slave trafficking) refers to the enslavement of any of the world's European ethnic groups throughout human history, whether perpetrated by non-Europeans or by other Europeans. Slavery in ancient Rome was frequently dependent on a person's socio-economic status and national affiliation and thus included European slaves.
It was also common for European people to be enslaved and traded in the Muslim world; European women, in particular, were highly sought-after to be concubines in the harems of many Muslim rulers. Examples of such slavery conducted in Islamic empires include the Arab slave trade, the Barbary slave trade, the Ottoman slave trade, and the Black Sea slave trade, among others.
Many different types of white people were enslaved. On the European continent under feudalism, there were various forms of status applied to people (such as serf, bordar, villein, vagabond, and slaves) who were indentured or forced to labor without pay.
During the Arab slave trade, Europeans were among those traded by the Arabs. The term Saqaliba (Arabic: صقالبة) was often used in medieval Arabic sources to refer specifically to Slavs being traded by the Arabs, but it could also refer more broadly to Central, Southern, and Eastern Europeans who were also traded by the Arabs, as well as all European slaves in some Muslim-controlled regions like Spain, including those abducted from raids on Spanish Christian kingdoms. During the era of the Fatimid Caliphate (909–1171), the majority of slaves were Europeans taken from European coasts and during conflicts.
Similarly, the Ottoman slave trade that included European captives was often fueled by raids into European territories or were taken as children in the form of a blood tax from the families of citizens of conquered territories to serve the empire for a variety of functions. In the mid-19th century, the term 'white slavery' was used to describe the Christian slaves that were sold into the Barbary slave trade in North Africa.
Slavery was a major institution and a significant part of the Ottoman Empire's economy and traditional society. The main sources of slaves were wars and politically organized enslavement expeditions in the Caucasus, Eastern Europe, Southern Europe, Central Europe, Southeast Europe, the Western Mediterranean and Africa. It has been reported that the selling price of slaves decreased after large military operations.
In Constantinople (present-day Istanbul), the administrative and political center of the Ottoman Empire, about a fifth of the 16th- and 17th-century population consisted of slaves. Statistics of these centuries suggest that Istanbul's additional slave imports from the Black Sea slave trade have totaled around 2.5 million from 1453 to 1700.
Individual members of the Ottoman slave class, called a kul in Turkish, could achieve high status in some positions. Eunuch harem guards and janissaries are some of the better known positions an enslaved person could hold, but enslaved women were actually often supervised by them. However, women played and held the most important roles within the harem institution.
A large percentage of officials in the Ottoman government were bought as slaves, raised free, and integral to the success of the Ottoman Empire from the 14th to 19th centuries. Many enslaved officials themselves owned numerous slaves, although the Sultan himself owned by far the most.
By raising and specially training slaves as officials in palace schools such as Enderun, where they were taught to serve the Sultan and other educational subjects, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.
Other slaves were simply laborers used for hard labor, such as for example agricultural laborers and galley slaves. Female slaves were primarily used as either domestic house servants or as concubines (sex slaves), who were subjected to harem gender segregation.
While there were slaves of many different ethnicities and race was not the determining factor in who could be enslaved, there was still a racial hierarchy among slaves since slaves were valued and assigned tasks and considered to have different abilities due to racial stereotypes.
Even after several measures to ban the slave trade and restrict slavery, introduced due to Western diplomatic pressure in the late 19th century, the practice continued largely unabated into the early 20th century.
