What were the effects of Mongol rule in Iran? This book focuses on Shiraz and the province of Fars to provide a detailed political, social and economic history of Ilkhanid rule from the first Mongol invasions in 1220 until the end of the Injuid Dynasty in 1357. Using a vast collection of sources, Denise Aigle combines local and global approaches to integrate the history of the province into the whole administrative system. Central is the thesis that Mongol rule caused a break in traditional administrative patterns.
