At the beginning of the 13th century the Hungarian kingdom was defining its eastern and south-eastern borders. In that period the regions of Transylvania and Banat where frequent subjected to raids undertaken by the Cumans. The Hungarian kings understood the importance of those two border regions and invited, at first, the Teutonic Order to settle in the Burzenland and then the Order of the Knights Hospitaller in the Banate of Severin to protect these key regions. This paper tries to present, if it is the case, the evolution and the relationship of these two orders within the medieval Hungarian administrative system.
