The aim of this study is to explore the system of connections among the natural-, social-, economical-, and infrastructural spheres in the historic development of Mezőhegyes, from the establishment of the Stud Farm (Ménesintézet) to the Trianon peace treaty, by the means of the tetrahedron-model developed by TÓTH JÓZSEF. The essence of the model is the following: the settlement is determined by four spheres –nature, society, economy and infrastructure- which are in close connections with each other. It can be modelled by a tetrahedron where each sphere (the four sides of the geometric solid) are in a very close and inseparable connection, the interaction can be observed at the edges. If there is a change in any elements (spheres) of the settlements, it affects the other three elements (spheres), as well, so the tetrahedron transforms completely.
