The Historical continuity of the Great Khorasan and Indian subcontinent from the first century to the first half of the seventh century AH; a new approach in historical studies

The contiguity of the Indian subcontinent and Great Khorasan in the Islamic period has connected the political history of these two regions. According to the historical reports, the development of Islam in the subcontinent and formation of Muslims government in India originated in Khorasan political changes. Also, Indians were present in political and military arenas of some Islamic governments of the Great Khorasan. Also, Ghazni, which was known as the gate of Khorasan to India, had a significant role in political events of Khorasan and India during this period. Hence, the main issue of the research is whether such these subjects indicate the historical continuity of the events of Great Khorasan and Indian subcontinent? Is the historical study of these two regions possible through this approach? In this research by considering political events relevant to these two regions in the first century to the first half of the seventh century AH and according to findings of this research, it is suggested that in Indology and Khorasan studies the common historical heritage of these two regions could be considered through a new approach.
