This thesis aims to analyse the historical, geographical and social roots behind the rise of the Neo-Taliban in August 2021. It would be reductive to link recent events in the country, namely the invasion of Western foreign troops and their final retreat, with the return of the Islamic extremist group. In order to explain contemporary events, one has to go back in time, and not only that, one has to analyse all aspects of a population and its history. As we shall see, however, that of Afghanistan is not at all an easy analysis to make. Its ethno-cultural matrix is full of different influences, positions and traditions, each of which is fundamental to an understanding of the country as a whole.An attempt is made to understand the geopolitical repercussions that present-day Afghanistan might have on international balances.
