The subject matter of this work consists a group of Attic black glazed pottery, which was discovered in Daskyleion between 1988-2004. The main objective of this work is to form a catalogue of this pottery, to evaluate them, and to draw out conclusions on the social, economic, cultural and political position of Daskyleion in the 5th century. The observations prove that almost all of the black glazed pottery shapes that were produced in Attica were used in Daskyleion in the 5th century. As a result of examining the material which consists of the subject matter of this work, it was proved that Daskyleion increased to import this pottery in the 5th century. It was also comprehended that there was a great increase in trade between Athens and Daskyleion in that period due to the strong and balanced situation of Daskyleion. Attic pottery, which was the most qualified, expensive, luxurious product in ancient time was imported to Daskyleion in the 5th century. This is the proof that Daskyleion lived its golden age in that period. As a matter of fact, the increasing import of Attic pottery should be the proof of the architectural activities that were attempted during the satrapal seat of Artabazos I. Finally, it is posible to say that Kyzikos had a role in the trade between Daskyleion and Athen.
