With the rise of the Safavids (1501-1732), Iran was reconstituted as a territorial state within borders not very different from those prevailing today. Shia Islam became the state religion, and monarchy once again became a central institution. Persian became unquestionably the language of administration and high culture. Although historians no longer assert that under the Safavids Iran emerged as a nation-state in the modern sense of the term, nevertheless by the seventeenth century the sense of Iranian identity and Iran as a state within roughly demarcated borders was more pronounced.
