Восточно-Франкское королевство
Also in 911, Louis the Child, the last Carolingian king of East Francia died, and nobles of Lotharingia, who had been loyal to him, under the leadership of Reginar, Duke of Lorraine declared Charles their new king, breaking from East Francia which had elected non-Carolingian Conrad I as the new king. Charles had tried to win Lotharingian support for years, for instance, by marrying in April 907 a Lotharingian woman named Frederuna, and in 909 his niece Cunigunda married Wigeric of Lotharingia. Charles defended Lotharingia against two attacks by Conrad I. In 925, Lotharingia was once again seized by East Francia.
