Concomitant with the formation of the Shiite states of Adel-Shahids, Nezam-Shahids and Qutb-Shahids, the emigration of the Shiite Iranians to the South India became more serious. The Shiite rulers of Deccan needed the Iranian emigrants for fixation of the Shiite governance and strengthening the foundations and promotion of Shiism as well as defending it against the non-Shiite states. This emigration caused evolutions in regard with political and social activities in line with religious and foreign policies of those states, and made the South India a safe area for inhabitants of those regions. The present article uses a descriptive-analytical approach based on library studies to explore and analyze the Iranian emigrant Shiites' measures in creating peace among the Shiite states of Deccan and answers the following questions: "what was the purpose of the Iranian Shiites in creating peace among the Shiite states of Deccan?" The findings of the study show that elites among the Iranian emigrant Shiites – with their perception of the special conditions and probable risks – served as the emissaries of peace before other Shiite rulers of Deccan to unite the Shiite states against the non-Shiite states, especially the Sunnite ones. In this way, by creating a united power and forming a defensive shield, they prevented lengthy wars. The important achievement of this peace was that people in the regions under the rule of the Shiite states of Deccan enjoyed social security. Besides, by performing this mission, the Iranians were seeking to fix and strengthen the Shiite state on the basis of the Shiite doctrines, so that they may prevent the collapse of the Shiite rule in Deccan.
