Adolphus Of Nassau, a German sovereign, born about 1250, fell in battle near Worms, July 2, 1298. He was the second son of Walram IV., count of Nassau, and was distinguished for valor in the service of Rudolph of Hapsburg. On the death of the latter he was, at the suggestion of the archbishop of Mentz, unanimously elected as his successor (May 10, 1292), in place of Rudolph's son and heir Albert. He was crowned at Aix-la-Chapelle as king of Germany, June 24, 1292, but not in Rome as emperor. Adolphus disgraced himself by accepting an English subsidy of £100,000 for joining in the war against France, and by backing out of the bargain without restoring the money. He further lost caste by his mercenary but fruitless transactions with the landgrave Albrecht of Thuringia for the acquisition of his territory. The archbishop of Mentz, in concert with Albert of Austria, caused Adolphus to be arraigned before the college of electoral princes. On his declining to comply with the summons, his deposition was proclaimed, June 23, 1298. But Adolphus appealed to the arbitrament of arms. The rivals met, with their respective armies, between the villages of Gollheim and Rosenthal, near Worms. Adolphus fell, hit in the face, as was reported at the time, by the lance of Albert, whose companions gave him the death blow.

Under Henry VII. his remains were placed beside those of his successor Albert I., in the vault of German sovereigns at Spire.
