Basically, the eastern borders of Iran, though as an example of the first newly-designated frontier lines in the world, can attract attention to those interested in geopolitical studies, but actually represent the territorial effects of political pressures and a long history of geopolitical struggles to backward and forward the scope of influence between the two imperialist empires of Russia and Britain and the collision of the two powers of the region, namely, Iran and India in the 19th century and the first years of the 20th century, that have affected the gradual development of the political geography of the Iranian plateau and led to the division of the lands of the Naderi empire in the Great Khorasan, Great Sistan and Great Baluchistan and the formation of the current Iranian border in the eastern side. The current research is descriptive-analytical and with the use of documentary resources and library studies, and by adopting a historical-geographical-political approach, it makes an attempt to answer this key question: which geopolitical factors have played a significant role in the formation and development of the current borders of Iran on the south-east side? The findings of this study show that various factors, including the political pressure imposed by the great game, the influential interventions of the British government in the course of border guerrillas, the weakness, inability and lack of awareness of the Qajar rulers on the legal principles governing the division of territories and the determination of the boundaries – when the modern political geography of the border territories of Iran was ruling the country, have played a significant role in the gradual formation of the current borders of Iran in this region.
