The Sasanian inscriptions of the fourth century CE are significant sources for studying the history, language, and geography of ancient Iran. This research examines key Sasanian inscriptions from this period, including the inscriptions of Shapur II and III at Taq-e Bostan, the inscriptions of Shapur Sakanshah and Saluk at Persepolis, and the Meshginshahr inscription. These inscriptions are particularly important from both geographical and historical perspectives. The inscriptions of Shapur Sakanshah and Saluk provide a clear representation of the eastern geography of the Sasanian Empire and its imperial borders, while the Meshginshahr inscription, as the only Middle Persian inscription in Azerbaijan, reflects the expansion of Sasanian language and culture in this region. This study first examines the content of these inscriptions and then analyzes their structure, language, and historical significance. Through a linguistic and historical approach, the research explores how political, social, and geographical transformations are reflected in these inscriptions. The findings indicate that these inscriptions not only served as instruments for legitimizing the power of Sasanian kings but also played a crucial role as historical records of religious and geographical changes during the Sasanian rule.
