Old Anatolian Turkish in the context of "Firman"

Jalāl al-Dīn Muḥammad Rūmī (Persian: جلال‌الدین محمّد رومی), or simply Rumi (30 September 1207 – 17 December 1273), was a Sufi mystic and poet whose followers went on to found the Mevlevi Order most famous for its whirling dervishes – a practice that he instigated. Rumi is a seminal figure in Sufism, or mystical Islam, whose thought and works loom large in both Persian literature and mystic poetry in general, with his translated works being enjoyed globally to this day.

Rumi's works are written in his mother tongue, Persian. He occasionally used the Arabic language and single Turkish and Greek words in his verse. His Masnavi (Mathnawi), composed in Konya, is considered one of the greatest poems of the Persian language. Rumi's influence has transcended national borders and ethnic divisions: Iranians, Afghans, Tajiks, Turks, Kurds, Greeks, Central Asian Muslims, as well as Muslims of the Indian subcontinent have greatly appreciated his spiritual legacy for the past seven centuries. His poetry influenced not only Persian literature, but also the literary traditions of the Ottoman Turkish, Chagatai, Pashto, Kurdish, Urdu, and Bengali languages.

The Artuqid dynasty (alternatively Artukid, Ortoqid, or Ortokid; Old Anatolian Turkish: أرتقي بيليك, Turkish: Artuklu Beyliği, Artuklular, pl. Artukoğulları) was established in 1102 as a Turkish principality of the Seljuk Empire. It formed a Turkoman dynasty rooted in the Oghuz Döğer tribe, and followed the Sunni Muslim faith. It ruled in Northern Syria and Upper Mesopotamia in the eleventh through thirteenth centuries. The Artuqid dynasty took its name from its founder, Artuk Bey, who was a member of Döger branch of the Oghuz Turks and ruled one of the Turkmen principalities of the Seljuk Empire. Artuk's sons and descendants ruled the three branches in the region: Sökmen's descendants ruled the region around Hasankeyf between 1102 and 1231; Ilghazi's branch ruled from Mardin and Mayyafariqin between 1106 and 1186 (until 1409 as vassals) and Aleppo from 1117–1128; and the Harput line starting in 1112 under the Sökmen branch, and was independent between 1185 and 1233.

The Zengid or Zangid dynasty, also referred to as the Atabegate of Mosul, Aleppo and Damascus (Arabic: أتابكة الموصل وحلب ودمشق), or the Zengid State (Old Anatolian Turkish: ظانغى دولتی, Modern Turkish: Zengî Devleti; Arabic: الدولة الزنكية, romanized: al-Dawla al-Zinkia) was initially an Atabegate of the Seljuk Empire created in 1127. It formed a Turkoman dynasty of Sunni Muslim faith, which ruled parts of the Levant and Upper Mesopotamia, and eventually seized control of Egypt in 1169. Imad ad-Din Zengi was the first ruler of the dynasty. In 1174, the Zengid state extended from Tripoli to Hamadan and from Yemen to Sivas, as it also included the Egyptian territories held by Saladin as governor in the name of Nur al-Din Zengi.

The Zengid Atabegate became famous in the Islamic world for its successes against the Crusaders, and for being the Atabegate from which Saladin originated. Following the demise of the Seljuk dynasty in 1194, the Zengids persisted for several decades as one of the "Seljuk successor-states" until 1250.

Germiyan, or the Germiyanids (Old Anatolian Turkish: كرميان; Turkish: Germiyanoğulları Beyliği or Germiyan Beyliği), were a dynasty that controlled parts of western Anatolia from c. 1300 to 1429. Germiyan first appeared in the 12th-century chronicles of Matthew of Edessa and The Georgian Chronicles when they fought against the County of Edessa and the Kingdom of Georgia. They reappeared in historical records of 1239 near Malatya, where they were tasked with suppressing the Babai revolt. The tribe relocated to western Anatolia with the encroaching Mongol invasion. During the reign of Yakub I (r. 1300–40), Germiyan gained sovereignty with the demise of the Sultanate of Rum and forged war with the neighboring Ottomans and the Byzantine Empire, which continued during his successor Mehmed's rule (r. 1340–61).

Amidst political tension caused by the neighboring Karamanids, Suleiman (r. 1361–87) married his daughter Devletşah Hatun to the Ottoman prince and future sultan, Bayezid I (r. 1389–1402). The process saw a major dowry payment that transferred much of the Germiyanid realm to Ottoman control, including the capital Kütahya. Yakub II (r. 1387–90, 1402–11) was initially on friendly terms with the Ottomans but eventually attempted to reclaim the former lands that were lost following his sister's wedding. He was jailed by his brother-in-law Bayezid I in 1390, and Germiyan wholly came under Ottoman control. Nine years later, Yakub escaped from prison and sought the protection of Timur (r. 1370–1405), who, after defeating Bayezid with the help of Yakub at the Battle of Ankara in 1402, restored Germiyan's former boundaries. In 1411, Kütahya fell to Mehmed II of Karaman (r. 1398–99, 1402–20), interrupting Yakub's reign a second time. His rule was reinstated by the Ottoman sultan, Mehmed I (r. 1413–21), upon the defeat of the Karamanids. Although Yakub meddled with the internal conflicts within the Ottomans, the triumph of Murad II (r. 1421–44, 1446–51) over his opponents forced Yakub to revert to amicable relations. Yakub lacked male heirs and left the sultanate to Murad II in his will shortly before he died in 1429.

Yunus Emre (Turkish pronunciation: [juːˈnus emˈɾe]), also known as Derviş Yûnus (Yûnus the Dervish; 1238–1320; Old Anatolian Turkish: يونس امره), was a Turkish folk poet and Sufi who greatly influenced Turkish culture. The UNESCO General Conference unanimously passed a resolution declaring 1991, the 750th anniversary of the poet's birth, International Yunus Emre Year.
