The article presents settlement relations in an entailed estate near Uniejów in the 19th and the beginning of the 20th century. Geo-historical analysis covers the issue of settlement origins and transformations, including the morphology of the countryside. It attempts a reconstruction of the circumstances of the origin of donation on the basis of a ukase (an edict of the tsar) of 1836, and presents, from the spatial perspective, the development of selected social and economic aspects of the functioning of the entailed estate in question. Special attention is devoted to changes in rural settlement resulting from two massive agrarian reforms which caused the transformation of rural settlement systems.
