These three volumes represent some of the most important historical sources for medieval Islamic scholarship. Yet the Persian of the original texts is often extremely difficult, even for accomplished scholars. Distinguished linguist and orientalist Wheeler Thackston here provides lucid, annotated translations that make this key material accessible to a wide range of scholars. Mirzar Haydar's 'Tarikh- i - Rashidi' provides a history of the of the Khans of Moghulistan, the vast stretch of territory between the ancient cities of Central Asia and Mongolia. Khwandamir's The Reign of the Mongol and the Turk covers the major empires and dynasties of the Persianate world from the 13th to the 16th century, including the conquests of the Mongols, Tamerlane, and the rise of the Safavids. The final volume, written by the grand vizier of the Mongol rulers of Iran, includes a valuable survey of the Turkic and Mongolian peoples, a history of Genghis Khan's ancestors, and a detailed account of his conquests.
