Excerpt from Page 331:"Depressing though the condition in the country may have been at the time of the fall of Safavids, they cannot be allowed to overshadow the achievements of the dynasty, which was in many respects to prove essential factors in the development of Persia in modern times. These include the maintanence of Persian as the official language and of the present-day boundaries of the country, adherence to the Twelever Shi'i, the monarchical system, the planning and architectural feartures of the urban centers, the centralised administration of the state, the alliance of the Shi'i Ulama with the merchant bazaars, and the symbiosis of the Persian-speaking population with important non-Persian, especially Turkish speaking minorities"
