What is "jalairs"

Jalair (/Jalair; ,also Djalair (~ Yyalair), Jalair ) is one of the Darliqin Mongol tribes according to Rashid-al-Din Hamadani's Jami' al-tawarikh. They lived along the Shilka River in modern Zabaykalsky Krai of Russia. After the Mongol conquest in the 13th century many Jalairs spread over Central Asia and the Middle East. Jalairs are one of the founding tribes of Mongolia's largest ethnic group Khalkha. Smaller clans named Jalayir are also found among the Inner Mongolians in China. The Jalayirs who stayed in Central Asia under the rules of Genghis Khan's older sons' descendants eventually adopted Turkic language. They are found among the Kazakhs of the Great jüz; also they are found among the Uzbeks (especially among Uzbeks of Southern Tajikistan and Afghanistan), Karakalpaks, and the Kyrgyz. The Jalairs who went to Iran, Iraq, and Afghanistan found the Jalairid Sultanate in 1330. The state was then taken over by the "Black sheep" Turks or Kara Koyunlu in 1432. Smaller numbers of powerful Jalair families lived in Khorasan, Iran as well as in the Mughal Empire until the 19th century.
