→Margrave of Baden · Margrave of Verona (sealing title) · Count in Ortenau and Brisgau (according to Wikipédia en)
Margrave of Baden of the House of Zähringen, Hermann V (c. 1180–1243) built the castle of Reichenberg, erected in 1230–1231 on a spur overlooking Oppenweiler in the Murr valley. Close to the Emperor Frederick II, he extended Baden's power between the middle Neckar and the Upper Rhine. Reichenberg, related in its dimensions and stonemasons' marks to the contemporary castles of Ebersberg and Besigheim, belongs to this territorial policy centred on Backnang, a town he probably founded.
Built in 1230–1231, Reichenberg was not a princely residence but a castle of ministerials serving as an administrative seat. Its technical kinship with Ebersberg and Besigheim, erected at the same time, suggests a coherent programme of fortifying Baden's possessions between the Murr and the Neckar, around Backnang. A second tower, now vanished, existed from the outset and was still standing in the 18th century. The exact dating varies according to the sources (1230–1231 according to Fritz and Schurig, 1225–1230 according to Burgen-web).
Birth; son of Margrave Hermann IV of Baden and Berthe of Tübingen.
Marries Irmengard, daughter of Count Palatine Henry the Welf and of the Staufen Agnes; this marriage brings him Pforzheim.
Renounces his wife's Brunswick possessions; in compensation, Frederick II pledges Lauffen, Eppingen and Sinsheim to him, enfeoffs him with Ettlingen and cedes Durlach to him as allodial property.
Takes part in the Sixth Crusade alongside Frederick II (according to Wikipédia en).
Has the castle of Reichenberg built above Oppenweiler; the knights Wolfram and Berthold von Reichenberg are mentioned in 1230.
Death; initially buried at Backnang, his remains are transferred in 1248 to Lichtenthal, an abbey founded by his widow in 1245 (according to Wikipédia en).
The Göttingen Academy's handbook of princely residences describes him as the most important Margrave of Baden of that name: through his marriage to a great-granddaughter of Henry the Lion and his agreements with Frederick II, he brought together Pforzheim, Durlach, Ettlingen and imperial pledges, and probably founded Backnang, Besigheim and Stuttgart.
