landlord of Orsova in 1382 through which he was obliged to forbid any foreign trader to enter Wallachia with merchandise and to keep guard of the border "day and night" reporting everything that happened, there is no mention of a Hungarian ban of Severin and Orsova appears as border point thus suggesting that the Eastern part of Banat was annexed by the Wallachian voievod Radu I. Maybe linked to this fact is the strange name given to the voievod in the biography of Sigismund of Luxembourg in which, speaking of Vlad Dracul, it is said that he was the son of "Merzeweydan" (Mircea) and grandson of "Pankraz dem Weisen" (Pankraz the Wise). The name Pankraz (Pancratius) is explained from the deterioration of the name Radu Ban (ban of Severin, title taken after the conquest of the territory). Nevertheless, the Wallachian voievod, in another Hungarian document which is contemporary with the events of 1377, bears the name "Godon" as well strange and unclear.

His activity as ctitor of religious establishments makes him one of the most active rulers of Wallachia, building a large number of churches with Tismana, Cozia and Cotmeana being the most important. Also, during his reign the two Catholic cathedrals from Severin (a. 1380)and Arges (9 mai 1381) are built and following the tradition, a Catholic monastery in Targoviste. Another important and controversial moment of his reign is represented by his, not well supported by evidences, ruling over the smaller of the two Bulgarian states in that moment - the Tsardom of Vidin. At the basis of this theory stands an illegible inscription on the walls of Curtea de Arges Cathedral in which, some researchers, identified the title „domn singur stăpânitor al Ungrovlahiei, al Vidinului și al oblastiei Vidinului“ ("sole ruler of Ungrovlahia, Vidin and the Oblast of Vidin"). It is true that the relations between the Wallachian rulers Vladislav I and Radu I and the Bulgarian Tsars from Tarnovo and Vidin, Shishman and Ivan Sratsimir were very tensed, the latter being themselves in conflicts
