The article examines Baltic German research expeditions to the north-western Caucasus, including Abkhazia, in the late 18th and early 19th centuries, and analyses the results of these trips. Although some of these researchers, such as Peter Simon Pallas and Heinrich Klaproth, came from Germany, most of the researchers were from the Baltic provinces of the Russian tsarist state: Johann Anton Güldenstädt, Otto Moritz Ludwig von Engelhardt, Johann Jacob Friedrich Wilhelm Parrot, and Theodor von Tornau. The main focus of the article is on the descriptions of the north-western region of Abkhazia, where the historical region Dzhigetia or Small Abkhazia is located, and which was inhabited by the Dzhiget ethnic group until the 1860s. Using data from Baltic German authors, especially Theodor von Tornau, an attempt is made to answer the question of whether or not Dzhigetians belonged to the Abkhazians. The article provides an overview of the historical location and fate of Dzhigets in the 19th century. In general, the descriptions of the peoples of the Caucasus provided by the authors of the late 18th and early 19th centuries are superficial and do not follow a uniform classification. Therefore, their interpretation offers different possibilities today. The examples of recent interpretations given in the article convince us that Russian and Abkhaz authors have interpreted earlier authors differently. The most comprehensive accounts of Dzhigetia come from Theodor von Tornau, and it can be argued that the Dzhigetians were an Abkhaz ethnic group. The question of the affiliation of Dzhigets is important in today’s border disputes between Abkhazia and Russia. In the last decade, Russia has made territorial claims to Abkhazia in the region of historic Dzhigetia. It is also declared among the Russian scientific community that Dzhigetia is not historically-ethnically within the borders of Abkhazia. However, Tornau’s data refute these statements of Russian authors. The ethnicity of the peoples of the border areas would probably not solve today’s border problems, but would give to the parties of the dispute symbolic capital and moral support to defend their positions.
