EBERHARD (?-939), duke of the Franks, brother of Con rad, duke of Franconia and German king (911-918) . In 915 Eber hard supported his brother against the rebel, Henry the Fowler of Saxony, but was defeated, and when Conrad died (918), Eber hard, at his brother's wish, carried to Henry the royal crown and sceptre, obtaining, however, for his support, almost complete independence for his own dukedom of Franconia. In 938 Eber hard rebelled against the new king, Otto the Great. He was defeated and fined, and his abettors condemned to carry dogs through the streets of Magdeburg. In the following year Eber hard, allied with the king's brother Henry and Gilbert of Lor raine, rebelled again, but was surprised and slain at Andernach on the Rhine.
