In order to understand better processes that were started by the campaign of Alexander the Great in southern Central Asia, the Czech-Uzbek team initiated a new field project in the Bactria - Sogdiana borderlands aiming to gain as much new spatial and chronological data on the period as possible. As a first step, extensive archaeological surface survey in the Baysun Mountains (south Uzbekistan) has been conducted in 2017 and 2018 in order to detect archaeological sites of the Hellenistic period, as well as to verify dating and interpretation of already known settlements in the given district.
The second step begun in autumn 2018 consisted of targeted trial excavations of selected sites allowing for more precise dating, interpretation and broader characterisation of the settlements of the "Hellenistic" period. The third step - in-depth analysis of the complex data and historical interpretation - is currently underway.
This paper presents the preliminary results of the ongoing project.
