This is the first in a three-volume set of the post-Islamic history of Zoroastrians of Yazd. It is based on original historic sources and written in Persian. This volume covers the lives of Zoroastrians of Yazd starting with the arrival of Islam in Iran, in 641 AD, until the formation of the Nasseri Anjoman of Yazd in 1892 AD.

This book discusses the treatment of Zoroastrians under the new Muslim rulers who regarded them as monotheists and people-of-the-book. It highlights two massive internal migrations to the Yazd region elevating its status as the center of Zoroastrianism. It also focuses on the formation of Akaber-Saheb Anjoman by Parsis and their efforts to abolish the Jazzieh tax and improve Zoroastrians' lives.

The author, Dr. Ali Tashakori is a historian and a history professor at the History Department of Yazd University (Yazd, Iran). He has authored numerous articles and five books prior to this landmark work.
