Golden Horde of the Mongol Empire. The Fergana became part of a larger Turco-Mongol empire. This Mongolian nomadic confederation known as Barlas, were remnants of the original Mongol army of Genghis Khan. After the Mongol conquest of Central Asia, the Barlas settled in Turkistan (which then became also known as Moghulistan - "Land of Mongols") and intermingled to a considerable degree with the local Turkic and Turkic-speaking population, so that at the time of Timur's reign the Barlas had become thoroughly Turkicized in terms of language and habits. Additionally, by adopting Islam, the Central Asian Turks and Mongols also adopted the Persian literary and high culture which had dominated Central Asia since the early days of Islamic influence. Persian literature was instrumental in the assimilation of the Timurid elite to the Perso-Islamic courtly culture. Heir to one of these confederations, Timur, founder of the Timurid dynasty, added the valley to a newly consolidated empire in the late 14th century, ruling the area from Samarkand. Located on the Northern Silk Road, the Fergana played a significant part in the flowering of medieval Central Asian Islam. Its most famous son is Babur, heir to Timur and famous conqueror and founder of the Mughal dynasty in Medieval India. Islamic proselytizers from the Fergana Valley such as al-Firghani الفرغاني, al-Andijani الأندجاني, al-Namangani النمنگاني, al-Khojandi الخوجندي spread Islam into parts of present-day Russia, China, and India. The Fergana valley was ruled by a series of Muslim states in the medieval period. For much of this period local and southwestern rulers divided the valley into a series of small states. From the 16th century, the Shaybanid Dynasty of the Khanate of Bukhara ruled Fergana, replaced by the Janid Dynasty of Bukhara in 1599. In 1709 Shaybanid emir Shahrukh of the Minglar Uzbeks declared independence from the Khanate of Bukhara, establishing a state in the eastern part of the Fergana Valley. He built a citadel to be his capital in the small town of Kokand. As the Khanate of Kokand, Kokand was capital of a territory stretching over modern eastern Uzbekistan and Tajikistan, southern Kazakhstan and all of Kyrgyzstan. Russian Empire Fergana was a province of Russian Turkestan, formed in 1876 out of the former khanate of Kokand. It was bounded by the provinces of Syr-darya in the North and Northwest, Samarkand in the West, and Zhetysu in the Northeast, by Chinese Turkestan (Kashgaria) in the East,
