The Study of Iran’s Eastern Boarder Transformations

Borders have a history as long as man’s life and their existence have not been doubted during the history and scholars believe that even globalization would not belittle them. On the other hand, creating the borderlines has mostly rooted in the formation of those lands and the various ethnic group inhabitations. The study of border transformations disperses the fogs over many realities in this regard. The history is a teachable and useful resource for anticipation of the communities’ behavior and identifying its facilitative and intervening factors pave the way for the better movement towards development. That is why the study of history is important and addressing the border issue and investigating its past transformations cycle, as a part of this study, can be beneficial. Since long, the southeastern lands of Iran have had a common culture with the original inhabitants of Iran plateau, especially with Khorasan and Kerman regions, but at different historical periods the vast geography of Iran and the various central powers, which had existed at some periods, have provided the potentials for political disintegration of Iran’s lands. This study aims at investigating the reasons behind the disintegration of some parts of the great Iran Empire, in spite of having the common cultural background at the mentioned historical period, and addressing the transformations of Iran eastern borders from the beginning until colonialism in those lands. This study has been conducted in the reviewing method and the relevant information has been compiled by studying the historical books and documents in this domain. The results of the investigations indicated that in each historical period the disintegration of some parts of Iran had different reasons; foreign raids, ignorance of central government, religious causes for division among people and people dissatisfaction are some of these reasons.
