A remarkable first-person narrative by a sixteenth-century Iranian ruler, the Memoirs of Shah Tahmasp I, Safavid Ruler of Iran (1514-1576), originally written in Persian, represent a vitally important primary source for the history of the Middle East in the period. In particular, the Memoirs shed light on the Safavid conflict with the Uzbeks and Ottomans, which played a decisive role in shaping the modern frontiers of the region. The Memoirs also represent an invaluable source for the internal political and religious life of the Safavid court, and the ways in which Shah Tahmasp, one of the most important rulers in Iranian history, wished to be remembered and viewed. This book represents the first English translation of this important text, and is furnished with an extensive introduction and notes that situate the work in its literary and historical context.
