The Shah made major changes to curb the power of certain ancient elite factions by expropriating large and medium-sized estates for the benefit of more than four million small farmers. In the White Revolution, he took a number of major modernization measures, including extending suffrage to women, much to the discontent and opposition of the Islamic clergy, the participation of workers in factories through shares and other measures, the improvement of the educational system through new elementary schools and literacy courses set up in remote villages by the Imperial Iranian Armed Forces. The latter step was called "Sepāh e Dānesh", "Army of Knowledge". As part of the White Revolution, the Armed Forces were engaged in infrastructural and other educational projects throughout the country ("Sepāh e Tarvij va Ābādāni") as well as in health education and promotion ("Sepāh e Behdāsht"). Moreover, he instituted exams for Islamic theologians to become established clerics. As a further step, in the seventies the governmental program of a free of charge nourishment for children at school ("Taghzieh e Rāigān") was implemented. Under the Shah's reign, the national Iranian income showed an unprecedented rise.
In the field of diplomacy, Iran realized and maintained friendly relations with Western and East European countries as well as the state of Israel and China and became, especially through the close friendship with the United States of America, more and more a hegemonial power in the Persian Gulf region and the Middle East. The suppression of the communist guerilla movement in the region of Dhofar in Oman with the help of the Iranian army after a formal request by Sultan Qaboos was widely regarded in this context. As to infrastructural and technological progress, the Shah continued and developed further the policies introduced by his father. As part of his programs, projects in several technologies, such as steel, telecommunications, petrochemical facilities, power plants, dams and the automobile industry may be named.
In terms of cultural activities, international cooperations were encouraged and organized, such as the Shiraz Festival of Arts. Many Iranian students were sent to and supported in foreign, especially Western countries and the Indian subcontinent. The Aryamehr University of Technology was established as a major new academic institution.
