As discussed in Chapter 2, from the middle of the sixteenth century, the Habsburgs as well as members of the Hungarian aristocracy thought of the Rába River and other minor waterways in the central part of Transdanubia as important chains in the frontier between the Ottoman and the Habsburg empires (including the Kingdom of Hungary). Because of this rather special role of the Rába in military defense, other factors besides economic benefits were also taken into consideration when making decisions about farming in the sixteenth and seventeenth centuries. In this chapter, using examples of individual settlements, I will examine the conflicts that were caused by the transformation of the roles of the river Rába and its region. Using the example of the town of Körmend and its manorial complex plus another settlement close by, Csákány, in the first half of the seventeenth century (up to c. 1660), I argue that the defense strategy sketched out in the previous chapter led to a complete transformation of the local environment, most importantly the flood regime of the river, causing serious economic difficulties in the Rába River's entire valley. These economic difficulties can with a high probability be attributed to the defensive role the river had in the period discussed.

Two immediate questions arise: why focus on Körmend, and why the first half of the seventeenth century? The reasons are relatively apparent. Körmend was one of the most significant settlements in the frontier zone.
