The topic of this thesis is medieval Hungarian and Polish nobility (as a Central European example) and English nobility (as a West European example) during 13th and 14th century, all of which are analyzed through couple of perspectives. The starting point of this thesis is an overview of the term nobility and comparisons between definitions found in encyclopedias and stated by central European and English historians in which certain differences are notable, especially in historiographic traditions which describe nobility in their inherent way. In the next two central chapters this thesis primarily reviews central European and English nobility, studying them with regard to lesser and greater nobility and their relations among themselves and with the king. In this part of the thesis it is possible to draw similarities between central and western European nobility and also, to the same extent, the differences which makes this topic very ample. Finally, one of the main differences between these two assorted nobilities is presented in the final chapter which introduces the historians’ evaluations of number of aforementioned nobilities.
