Chagatay language in the context of "Barlas"

Mīrzā Muhammad Tarāghāy bin Shāhrukh (Chagatay: میرزا محمد تراغای بن شاهرخ; Persian: میرزا محمد طارق بن شاهرخ), better known as Ulugh Beg (Persian: الغ‌بیک; 22 March 1394 – 27 October 1449), was a Timurid sultan, as well as an astronomer and mathematician.

Ulugh Beg was notable for his work in astronomy-related mathematics, such as trigonometry and spherical geometry, as well as his general interests in the arts and intellectual activities. It is thought that he spoke five languages: Arabic, Persian, Chaghatai Turkic, Mongolian, and a small amount of Chinese. During his rule (first as a governor, then outright) the Timurid Empire achieved the cultural peak of the Timurid Renaissance through his attention and patronage. Samarkand was captured and given to Ulugh Beg by his father Shah Rukh.

The Khanate of Kokand (Persian: خان‌نشین خوقند, Chagatay: خوقند خانليغى) was an early modern state in the Fergana Valley of Central Asia. At its peak, it stretched from the Ulu Tau mountains in the north, Sariqol in the south, Aq Masjid in the west, and Karakol in the east. Its territory is today divided between Uzbekistan, Kyrgyzstan, Tajikistan, and Kazakhstan.

It was established during the decline of the Khanate of Bukhara by Shahrukh Biy, the leader of the Ming tribe of Uzbeks. It developed into a multi-ethnic polity with a diverse population of sedentary Turkic and Persian-speaking communities (collectively referred to as Sarts), nomadic Turco-Mongol tribes, and Pamiri groups. It was similar to its predecessors in numerous aspects, including its internal organization, such as civilian and military personnel having Perso-Islamic and Turco-Mongol titles.

The Manghud, or Manghit (Mongolian: Мангуд, romanized: Mangud; Chagatay: منقت, romanized: Manqït; Uzbek: Mangʻit) were a Mongol tribe of the Urud-Manghud federation and mainly a sub-clan of Borjigin, but later remixed with Golden Ultai, Genghis Khan Imperial Borjigin Descent like Nogai Khan, The Manghuds (also spelled Mangkits or Mangits) who moved to the Desht-i Qipchaq steppe became Turkified. They established the Nogai Horde in the 14th century and the Manghit dynasty to rule the Emirate of Bukhara in 1785. They took the Islamic title of Emir instead of the title of Khan, since they were not descendants of Genghis Khan and rather based their legitimacy as rulers on Islam. However, Persian historian Rashid-al-Din Hamadani who chronicled the Mongols, claimed that many old Mongolian clans (such as Barlas, Urad, Manghud, Taichiut, Chonos, Kiyat) were founded by Borjigin members. The clan name was used for Mongol vanguards as well. Members of the clan live in several regions of Central Asia and Mongolia.

The Khanate of Khiva (Chagatay: خیوه خانلیگی, romanized: Khivâ Khânligi, Persian: خانات خیوه, romanized: Khânât-e Khiveh, Uzbek: Xiva xonligi, Хива хонлиги, Turkmen: Hywa hanlygy, Russian: Хивинское ханство, romanized: Khivinskoye khanstvo) was an Uzbek monarchy that existed in the historical region of Khorezm from 1511 to 1920, except for a period of Afsharid occupation by Nader Shah between 1740 and 1746. Centred in the irrigated plains of the lower Amu Darya, south of the Aral Sea, with the capital in the city of Khiva. It covered present-day western Uzbekistan, southwestern Kazakhstan and much of Turkmenistan before the Russian conquest at the second half of the 19th century.

In 1873, the Khanate of Khiva was greatly reduced in size and became a Russian protectorate. The other regional protectorate that lasted until the Revolution was the Emirate of Bukhara. Following the Russian Revolution of 1917, Khiva had a revolution too, and in 1920 the Khanate was replaced by the Khorezm People's Soviet Republic. In 1924, the area was formally incorporated into the Soviet Union and today it is largely a part of Karakalpakstan, Xorazm Region in Uzbekistan, and Daşoguz Region of Turkmenistan.
