The main intent of this thesis is to review the history and roots of the Cossack assembly, and to analyze its connection to western civilization. In terms of the roots of the Cossack assembly, this thesis will explore the Scytho-Sarmatian, the early Slavic, the Novgorodian, as well as the Turkic-Mongol influences that led to its creation. While the Zaporozhian Cossack assembly will be discussed, the primary focus of the history of the Cossack assembly section will deal with the Don Cossacks’ assembly, since the practices and traditions inherent in this structure are representative of most Cossack groups. In addition to reviewing the Sarmatian Hypothesis, this thesis will also examine the connections and parallels between the Arthurian legends, the ancient Iranian governing practices, and the Cossack assembly. It is thus hoped that this multileveled analysis will generate a comprehensive portrait of the Cossack assembly and, through its ancient Iranian predecessor’s connection to the Arthurian Round Table, prompt a reconsideration of analytical approaches to both the foundations of Cossack and western democracy. / text
