Mohammad Reza Shah took the title Shahanshah ("King of Kings") on 26 October 1967. He was the second and last monarch of the House of Pahlavi. Mohammad Reza Shah Pahlavi held several other titles, including that of Aryamehr ("Light of the Aryans") and Bozorg Arteshtaran ("Commander-in-Chief"). His dream of what he referred to as a "Great Civilisation" (Persian: تمدن بزرگ‎, romanized: tamadon-e bozorg) in Iran led to a rapid industrial and military modernisation, as well as economic and social reforms.
