Reza Shah, helped shape Iranian nationalism by infusing it with a distinctly secular ideology, and diminishing the influence of Islam on Iran. By integrating European legal policies in the place of Islamic courts, Shah reassured the efficiency of the state bureaucracy and promoted a strong sense of Iranian nationalism.[10] In addition, Reza Shah sought to change the names of various towns to honor pre-Islamic Persian kings and mythological heroes, and to continue to reduce the power of the mullahs by seeking to modernize Iran. The Pahlavi dynasty thus was set irrevocably down the road towards infusing the country with a form of secular nationalism, a path that would eventually bring it into conflict with the country's clerical class.
