The essence of the study is an analysis of the so-called "Majestätsquaterne", special series of the Moravian Land Registers (Landtafeln), which recorded the admission of new members to the community of Moravian land estates in the period 1642–1852. As part of this so-called habilitation process in the land, the applicant had to prove that he had an incolat and aristocratic status (by means of an incolat and ennoblement charter), swear a personal oath of loyalty to the monarch (by means of intimation of the Court Chancery) and submit a binding statement in the written form of Relation to the Land (Revers zum Lande) to the land government (i.e., a written oath to uphold the land's constitution, laws, and customs). The study outlines the habilitation process in the land and then goes on to address: the formal and content aspects of the "Majestätsquaterne"; the role of the court and land administrations involved; and individual depositors and the written material produced by them. It reconstructs the practise of registration and shows the resulting compositional scheme of individual registred documents and their classification according to traditional diplomatic categories, including an evaluation of selected internal and external features.
