The present publication covers the entire collection of Slovenian oaths created up to the middle of the 19th century by two types of author: boroughs (12 texts) and non-agricultural professional groups (6 texts). The majority of the 18 texts included in the book first saw the light of day in six Styrian boroughs, in particular in Središče ob Dravi (5), while only four are from Carniola, two are from Prekmurje and one is from Carinthia. The texts of oath originate from a span of time with the possible extremes of 1611 and 1846. The principal aim of the publication is to present the texts themselves (with a facsimile, diplomatic and critical copy in TEI XML) with appropriate commentary, which will facilitate further study. The discussion focuses on the historical aspect: the circumstances and time of the emergence of the oath, its treatment to date, its content in brief, its role in the social environment, and its further significance in time and space.
