Ibn Khaldun in the context of "Timur"

Nomadic empires, sometimes also called steppe empires, Central or Inner Asian empires, were the empires erected by the bow-wielding, horse-riding, nomadic people in the Eurasian Steppe, from classical antiquity (Scythia) to the early modern era (Dzungars). They are the most prominent example of non-sedentary polities.

Some nomadic empires consolidated by establishing a capital city inside a conquered sedentary state and then exploiting the existing bureaucrats and commercial resources of that non-nomadic society. In such a scenario, the originally nomadic dynasty may become culturally assimilated to the culture of the occupied nation before it is ultimately overthrown. Ibn Khaldun (1332–1406) described a similar cycle on a smaller scale in 1377 in his Asabiyyah theory.

Georges Duby (French: [ʒɔʁʒ dybi]; 7 October 1919 – 3 December 1996) was a French historian who specialised in the social and economic history of the Middle Ages. He ranks among the most influential medieval historians of the twentieth century and was one of France's most prominent public intellectuals from the 1970s to his death. In 2019, his work was published in the Bibliothèque de la Pléiade. He is one of the rare historians to benefit from such an honor, with Herodotus, Thucydides, Ibn Khaldoun, Froissart and Michelet.

'Asabiyyah (Arabic: عصبيّة, romanized: ʿaṣabiyya, also 'asabiyya, 'group feeling' or 'social cohesion') is a concept of social solidarity with an emphasis on unity, group consciousness, and a sense of shared purpose and social cohesion, originally primarily used in the context of tribalism and clanism. In the modern period, it is generally analogous to solidarity. However, it is often negatively associated because it can widely used in ethnically and linguistically nationalism or partisanship, i.e., loyalty to one's group regardless of circumstances.

The concept was familiar in the pre-Islamic era, but became popularized in Ibn Khaldun's Muqaddimah, in which it is described as the fundamental bond of human society and the basic motive force of history, pure only in its nomadic form. Ibn Khaldun argued that asabiyya is cyclical and directly relevant to the rise and fall of civilizations: it is strongest at the start of a civilization, declines as the civilization advances, and then another more compelling asabiyyah eventually takes its place to help establish a different civilization.

Muḥammad ibn Muḥammad ibn al-Ḥasan al-Ṭūsī (1201 – 1274), also known as Naṣīr al-Dīn al-Ṭūsī (Arabic: نصیر الدین الطوسی; Persian: نصیر الدین طوسی) or simply as (al-)Tusi, was a Persian polymath, architect, philosopher, physician, scientist, and theologian. Nasir al-Din al-Tusi was a well published author, writing on subjects of math, engineering, prose, and mysticism. Additionally, al-Tusi made several scientific advancements. In astronomy, al-Tusi created very accurate tables of planetary motion, an updated planetary model, and critiques of Ptolemaic astronomy. He also made strides in logic, mathematics but especially trigonometry, biology, and chemistry. Nasir al-Din al-Tusi left behind a great legacy as well. Tusi is widely regarded as one of the greatest scientists of medieval Islam, since he is often considered the creator of trigonometry as a mathematical discipline in its own right. The Muslim scholar Ibn Khaldun (1332–1406) considered Tusi to be the greatest of the later Persian scholars. There is also reason to believe that he may have influenced Copernican heliocentrism.

The Hamrin Mountains (Arabic: جبل حمرين, romanized: Jabāl Hamrīn, Kurdish: چیای حەمرین, romanized: Çiyayê Hemrîn or Çiyayên Hemrîn) are a small mountain ridge in northeast Iraq. The westernmost ripple of the Zagros Mountains, the Hamrin mountains extend from the Diyala Governorate bordering Iran, northwest to the Tigris river, crossing northern Saladin Governorate and southern Kirkuk Governorate.

Historically the Hamrin mountains were called Barima, Bārimā and Birimma (Arabic: جبل بارِمّا, romanized: Jabāl Bārimā). Ibn Khaldun, a 14th century historian called the Hamrin mountains range, the "Kurdish mountains". That is because these mountains are situated in the south of Kirkuk and Kurds live there, so, Ibn Khaldun said, "the range Hamrin mountains is a place whose people are Kurdish."

The Muqaddimah (Arabic: مقدّمة "Introduction"), also known as the Muqaddimah of Ibn Khaldun (Arabic: مقدّمة ابن خلدون) or Ibn Khaldun's Prolegomena (Ancient Greek: Προλεγόμενα), is a book written by the historian Ibn Khaldun in 1377 which presents a view of universal history. Some modern thinkers view it as the first work dealing with the social sciences of sociology, demography, and cultural history. The Muqaddimah also deals with Islamic theology, historiography, the philosophy of history, economics, political theory, and ecology. It has also been described as a precursor or an early representative of social Darwinism, and Darwinism.

Ibn Khaldun wrote the work in 1377 as the introduction and the first book of his planned work of world history, the Kitab al-ʿIbar ("Book of Lessons"; full title: Kitābu l-ʻibari wa Dīwāni l-Mubtada' wal-Ḥabar fī ayāmi l-ʻarab wal-ʿajam wal-barbar, waman ʻĀsarahum min Dhawī sh-Shalṭāni l-Akbār, i.e.: "Book of Lessons, Record of Beginnings and Events in the history of the Arabs and Foreigners and Berbers and their Powerful Contemporaries"), but already in his lifetime it became regarded as an independent work on its own.

Sundiata Keita (Mandinka, Malinke: [sʊndʒæta keɪta]; c. 1217 – c. 1255, N'Ko spelling: ߛߏ߲߬ߖߘߊ߬ ߞߋߕߊ߬; also known as Manding Diara, Lion of Mali, Sogolon Djata, son of Sogolon, Nare Maghan and Sogo Sogo Simbon Salaba) was a prince and founder of the Mali Empire. He was also the great-uncle of the Malian ruler Mansa Musa, who is usually regarded as the wealthiest person of all time, although there are no reliable ways to accurately calculate his wealth.

Written sources augment the Mande oral histories, with the Moroccan traveller Muhammad ibn Battúta (1304–1368) and the Tunisian historian Ibn Khaldun (1332–1406) both having travelled to Mali in the century after Sundiata's death, and providing independent verification of his existence. The semi-historical but legendary Epic of Sundiata by the Malinké/Maninka people centers on his life. The epic poem is primarily known through oral tradition, transmitted by generations of Maninka griots (djeli or jeliw). The Manden Charter issued during his reign is listed by UNESCO as one of an intangible cultural heritage.
