Ghilman in the context of Janissary Corps

Mamluk or Mamaluk (/ˈmæmluːk/; Arabic: مملوك, romanized: mamlūk (singular), مماليك, mamālīk (plural); translated as "one who is owned", meaning "slave") were non-Arab, ethnically diverse (mostly Turkic, Caucasian, Mongol, Eastern and Southeastern European) enslaved mercenaries, slave-soldiers, and freed slaves who were assigned high-ranking military and administrative duties in the Muslim world.

The most enduring Mamluk realm was the knightly military class in medieval Egypt, which developed from the ranks of slave-soldiers. Originally the Mamluks were slaves of Turkic origins from the Eurasian Steppe, but the institution of military slavery spread to include Circassians, Mongols, Abkhazians, Georgians, Armenians, Russians, and Hungarians, as well as peoples from the Balkans such as Albanians, Greeks, and South Slavs (see Saqaliba). They also recruited from the Egyptians. The "Mamluk/­Ghulam Phe­nom­enon", as David Ayalon dubbed the creation of the specific warrior class, was of great political importance; for one thing, it endured for nearly 1,000 years, from the 9th century to the early 19th. (See: Ghilman.)

Taj al-Din Yildiz (also spelled Yaldiz, Yildoz, and Yalduz, Persian: تاج‌ الدین یلدوز) was a Turkic ghulam of the Ghurid dynasty, who, after the death of Sultan Muhammad of Ghor, became the de facto ruler of Ghazni, while, however, still recognizing Ghurid authority.

A janissary (UK: /ˈdʒænɪsəri/ JAN-iss-ər-ee, US: /-sɛri/ -⁠err-ee; Ottoman Turkish: یڭیچری, romanized: yeñiçeri, IPA: [jeˈŋit͡ʃeɾ̞i], lit. 'new soldier') was a member of the elite infantry units that formed the Ottoman sultan's household troops. They were the first modern standing army, and perhaps the first infantry force in the world to be equipped with firearms, adopted during the reign of Murad II (r. 1421–1444, 1446–1451). The corps was established under either Orhan or Murad I, and dismantled by Mahmud II in 1826.

Janissaries began as an elite corps made up through the devşirme system of child levy enslavement, by which Christian boys, chiefly from the Balkans, were taken, levied, subjected to forced circumcision and forced conversion to Islam, and incorporated into the Ottoman army. They became famed for internal cohesion cemented by strict discipline and order. Unlike typical slaves, they were paid regular salaries. Forbidden to marry before the age of 40 or engage in trade, their complete loyalty to the Ottoman sultan was expected. By the 17th century, due to a dramatic increase in the size of the Ottoman standing army, the corps' initially strict recruitment policy was relaxed. Civilians bought their way into it in order to benefit from the improved socio-economic status it conferred upon them. Consequently, the corps gradually lost its military character, undergoing a process that has been described as "civilianization".

Anushtegin Gharchai (also spelled Anush-Tegin; Persian: نوشتکین غرچه, romanized: Anūštigin Ḡaṛčaʾī; died 1097) was a Turkic slave commander (ghulam) of the Seljuks and the governor of Khwarazm from approximately 1077 until 1097. He was the first member of his family to play a role in the history of Khwarazm, and the namesake for the dynasty that would rule the province in the 12th and early 13th centuries.

'Alā' al-Din Muhammad II (Persian: علاءالدین محمد خوارزمشاه; full name: Ala ad-Dunya wa ad-Din Abul-Fath Muhammad Sanjar ibn Tekish) was the Shah of the Khwarazmian Empire from 3 August 1200 to 11 January 1221. His ancestor was Anushtegin Gharchai, a Turkic Ghulam who eventually became a viceroy of a small province in Central Asia named Khwarazm. He was subjected to the Mongol invasion of the Khwarazmian Empire, which resulted in the utter destruction of his empire.

The Bukhara slave trade refers to the historical slave trade conducted in the city of Bukhara in Central Asia (present-day Uzbekistan) from antiquity until the 19th century. Bukhara and nearby Khiva were known as the major centers of slave trade in Central Asia for centuries until the completion of the Russian conquest of Central Asia in the late 19th century.

The city of Bukhara was an important trade center along the ancient Silk Road, through which slaves were traded between Europe and Asia. In the Middle Ages, Bukhara came to lie in the religious border zone between the Muslim and non-Muslim world, which was seen as a legitimate target of slavery by Muslims, and referred to as the "Eastern Dome of Islam". It became the center of the massive slave trade of the Samanid Empire, who bought saqaliba (European) slaves from the Kievan Rus' and sold them on to the Middle East, and as such constituted one of the main trade routes of saqaliba slaves to the Muslim world. The conquests and plundering of the Ghaznavid Empire brought a large number of slaves from India into the markets of Bukhara in the 10th and 11th centuries. Bukhara was also a center for the trade of non-Muslim Turkic slaves from Central Asia to the Middle East and India, where they composed the main ethnicity of ghilman (military slaves) for centuries.

Saqaliba (Arabic: صقالبة, romanized: ṣaqāliba, singular Arabic: صقلبي, romanized: ṣaqlabī) was a term used in medieval Arabic sources, initially to refer to Slavs, but it also came to be used as a designation for European slaves in Muslim countries in the 10th and 11th centuries. In the Arab world, the Saqaliba served as servants, harem concubines, eunuchs, craftsmen, mercenaries, slave soldiers, and as Caliph's guards. In the Iberian Peninsula, their military role may be compared with that of mamluks in the Ottoman Empire. Many rose to prominent positions in the caliphates of the Maghreb, and some became rulers of taifas (small independent states) in Levante at the beginning of the 11th century (known as the "Amirids").

Abū Isḥāq Muḥammad ibn Hārūn al-Rashīd (Arabic: أبو إسحاق محمد بن هارون الرشيد; October 796 – 5 January 842), better known by his regnal name al-Muʿtaṣim biʾllāh (المعتصم بالله, lit. 'He who seeks refuge in God'), was the eighth Abbasid caliph, ruling from 833 until his death in 842. When al-Ma'mun died unexpectedly on campaign in August 833, al-Mu'tasim was thus well placed to succeed him, with the support of the powerful chief qādī, Ahmad ibn Abi Duwad, he continued to implement the rationalist Islamic doctrine of Mu'tazilism and implementing miḥna policy.

A younger son of Caliph Harun al-Rashid (r. 786–809), he rose to prominence through his formation of a private army composed predominantly of Turkic slave-soldiers (ghilmān, sing. ghulām). This proved useful to his half-brother, Caliph al-Ma'mun, who employed al-Mu'tasim and his Turkish guard to counterbalance other powerful interest groups in the state, as well as employing them in campaigns against rebels and the Byzantine Empire.

The Numayrids (Arabic: النميريون) were an Arab dynasty based in Diyar Mudar (western Upper Mesopotamia). They were emirs (princes) of their namesake tribe, the Banu Numayr. The senior branch of the dynasty, founded by Waththab ibn Sabiq in 990, ruled the Euphrates cities of Harran, Saruj and Raqqa more or less continuously until the late 11th century. In the early part of Waththab's reign (r. 990–1019), the Numayrids also controlled Edessa until the Byzantines conquered it in the early 1030s. In 1062, the Numayrids lost Raqqa to their distant kinsmen and erstwhile allies, the Mirdasids, while by 1081, their capital Harran and nearby Saruj were conquered by the Turkish Seljuks and their Arab Uqaylid allies. Numayrid emirs continued to hold isolated fortresses in Upper Mesopotamia, such as Qal'at an-Najm and Sinn Ibn Utayr near Samosata until the early 12th century, but nothing is heard of them after 1120.

As Bedouin (nomadic Arabs), most Numayrid emirs avoided settled life in the cities they controlled; rather, they ruled their emirates (principalities) from their tribal encampments in the countryside, while entrusting administration of the cities to their ghilmān (military slaves). An exception was Emir Mani' ibn Shabib (r. ca. 1044–1063), under whom the Numayrids reached their territorial peak. Mani' resided inside Harran, transforming its Sabian temple into an ornate, fortified palace. The Numayrids were Shia Muslims and initially recognized the religious sovereignty of the Sunni Muslim Abbasid Caliphate, at least nominally, but later switched allegiance to the Shia Fatimid Caliphate after the latter extended its influence into northern Syria in 1037. By 1060, they likely reverted to Abbasid suzerainty.
