Emirate of Bukhara
The Emirate of Bukhara was an Uzbek absolute monarchy in Central Asia that existed from 1785 to 1920 in what is now parts of Tajikistan, Uzbekistan, Turkmenistan and Kazakhstan. It occupied the land between the Amu Darya and Syr Darya rivers, known formerly as Transoxiana. Its core territory was the fertile land along the lower Zarafshon river, and its urban centres were the ancient cities of Samarqand and the emirate's capital, Bukhara. It was contemporaneous with the Khanate of Khiva to the west, in Khwarazm, and the Khanate of Kokand to the east, in Fergana.
