This fine book provides the first comprehensive account of the Indian merchant communities that arose in Central Asia in the 16th century and continued to occupy an important niche in the local economy until the turn of the 20th century. The subject of India's relations with Central Asia and Russia has often been addressed, but it has usually fallen afoul of methodological and linguistic boundaries that divide the historiographies of the two regions. This is the first work that is equally at home in both Indian and Central Asian history. Levi's greatest contribution is to bring Central Asian sources to bear fully on his argument. He uses Persian-language narrative and documentary sources from Central Asia (housed in the manuscript collections of the Beruni Institute of Oriental Studies in Tashkent) and the state archives of Uzbekistan to glean useful new information about life in the diaspora and the activities of its members. He backs these up with accounts of European travelers, which he has mined with great thoroughness for all references to Indian merchants.
