Former political borders and their impact on the evolution of the present-day spatial structure of agriculture in Poland

The paper deals with the results of an analysis of the spatial structure of agriculture in Poland which was aimed at assessing the impact of the historical factor. The territory of present-day Poland includes the political borders of the 19th and 20th centuries which divided the area into two parts: western (Kingdom of Prussia and the land belonging to Poland and Germany in the interwar period) and eastern (the land of the Russian Empire and the Austro-Hungarian Empire which later belonged to Poland in the interwar period). The historical factor and its impact were examined also in the comparative analysis of two adjoining stretches of land accepted as territorial units (East Poland and West Poland). We showed that historical borders constitute an important element affecting the evolution of the spatial structure of Polish agriculture. The impact of the historical factor was shown to be the strongest for the differences in the features associated with agrarian structure, rural socio-demography, and productivity and profitability of agricultural holdings.
