Turco-Persian tradition in the context of "Seljuk dynasty"

Persians, or the Persian people, are an Iranian ethnic group from West Asia. They are indigenous to the Iranian plateau and comprise the majority of the population of Iran. They have a common cultural system and are native speakers of the Persian language. In the Western world, "Persian" was largely understood as a demonym for all Iranians rather than as an ethnonym for the Persian people, but this understanding shifted in the 20th century.

The Persians were originally an ancient Iranian people who had migrated to Persis (also called "Persia proper" and corresponding with Iran's Fars Province) by the 9th century BCE. Together with their compatriots, they established and ruled some of the world's most powerful empires, which are well-recognized for their massive cultural, political, and social influence in the ancient Near East and beyond. The Persian people have contributed greatly to art and science, and Persian literature is one of the world's most prominent literary traditions both inside and outside of Iran. The regional prestige of their civilization was the basis for the development of many noteworthy Persianate societies, especially among the Turkic peoples, throughout Central Asia and South Asia.

The Seljuk Empire, or the Great Seljuk Empire, was a high medieval, culturally Turco-Persian, Sunni Muslim empire, established and ruled by the Qïnïq branch of Oghuz Turks. The empire spanned a total area of 3.9 million square kilometres (1.5 million square miles) from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south, and it spanned the time period 1037–1308, though Seljuk rule beyond the Anatolian peninsula ended in 1194.

The Seljuk Empire was founded in 1037 by Tughril (990–1063) and his brother Chaghri (989–1060), both of whom co-ruled over its territories; there are indications that the Seljuk leadership otherwise functioned as a triumvirate and thus included Musa Yabghu, the uncle of the aforementioned two.

The Sultanate of Rum, or Seljuk Empire of Rum, was a culturally Turco-Persian Sunni Muslim state, established over conquered Byzantine territories and peoples (Rum) of Anatolia by the Seljuk Turks following their entry into Anatolia after the Battle of Manzikert in 1071. The name Rum was a synonym for the medieval Eastern Roman Empire and its peoples, as it remains in modern Turkish. The name is derived from the Aramaic (romī) and Parthian (frwm) names for ancient Rome, via the Greek Ῥωμαῖοι (Romaioi) meaning Anatolia. It is considered to be the beginning of Turkish history in Anatolia.

The Sultanate of Rum seceded from the Seljuk Empire under Suleiman ibn Qutalmish in 1077. It had its capital first at Nicaea and then at Iconium. It reached the height of its power during the late 12th and early 13th century, when it succeeded in taking key Byzantine ports on the Mediterranean and Black Sea coasts. In the east, the sultanate reached Lake Van. Trade through Anatolia from Iran and Central Asia was developed by a system of caravanserai. Especially strong trade ties with the Genoese formed during this period. The increased wealth allowed the sultanate to absorb other Turkish states that had been established following the conquest of Byzantine Anatolia: Danishmendids, House of Mengüjek, Saltukids, Artuqids.

Indo-Persian culture refers to a cultural synthesis present on the Indian subcontinent. It is characterised by the absorption or integration of Persian aspects into the various cultures of modern-day republics of Bangladesh, India, and Pakistan. The earliest introduction of Persian influence and culture to the subcontinent was by various Muslim Turko-Persian rulers, such as the 11th-century Sultan Mahmud Ghaznavi, rapidly pushed for the heavy Persianization of conquered territories in northwestern Indian subcontinent, where Islamic influence was also firmly established. This socio-cultural synthesis arose steadily through the Delhi Sultanate from the 13th to 16th centuries, and the Mughal Empire from then onwards until the 19th century. Various dynasties of Turkic, Iranian and local Indian origin patronized the Persian language and contributed to the development of a Persian culture in India. The Delhi Sultanate developed their own cultural and political identity which built upon Persian and Indic languages, literature and arts, which formed the basis of an Indo-Muslim civilization.

Persian was the official language of most Muslim dynasties in the Indian subcontinent, such as the Delhi Sultanate, the Kashmir Sultanate, the Bengal Sultanate, the Mughal Empire and their successor states, and the Sikh Empire. It was also the dominant cultured language of poetry and literature. Many of the Sultans and nobility in the Sultanate period were Persianised Turks from Central Asia who spoke Turkic languages as their mother tongues. The Mughals were also culturally Persianised Central Asians (of Turko-Mongol origin on their paternal side), but spoke Chagatai Turkic as their first language at the beginning, before eventually adopting Persian. Persian became the preferred language of the Muslim elite of northern India. Muzaffar Alam, a noted scholar of Mughal and Indo-Persian history, suggests that Persian became the official lingua franca of the Mughal Empire under Akbar for various political and social factors due to its non-sectarian and fluid nature. The influence of these languages led to a vernacular called Hindustani that is the direct ancestor language of today's Hindi–Urdu varieties.

A nāḥiyah (Arabic: نَاحِيَة [ˈnaːħijah], plural نَوَاحِي, nawāḥī [naˈwaːħiː]), also nahiyeh, nahiya or nahia, is a regional or local type of administrative division that usually consists of a number of villages or sometimes smaller towns. The Ottoman nahiye, also called a bucak, was a third-level or lower administrative division, and remains as such in some successor states such as Syria, Iraq, Lebanon and Jordan, with the Balkan states of Serbia and Montenegro having preserved the term for a while after liberation for the highest administrative unit as nahija. In Tajikistan and the autonomous Chinese region of Xinjiang, both from the Turco-Persian or Turkic regions of Asia, it is a second- and third-level division, respectively. A nahiyah can constitute a division of a qadaa, mintaqah or other such district-type division and is sometimes translated as "subdistrict".
