The family is first mentioned in 832, with Count Gebhard in the lower Lahn region. His sons are mentioned in 861 as propinqui (close relatives) of Adalard the Seneschal, who had served Louis the Pious. But the clan's rise to prominence began with Oda, wife of Emperor Arnulf of Carinthia, who was a member of the family. In view of his family relationship with Oda, Conrad the Elder was frequently referred to as nepos (nephew, grandson, descendant) of the Emperor. He and his brothers apparently were in fact Arnulf's closest relatives, and he relied heavily on their support in his feud with the counts of Babenberg. Arnulf rewarded them by helping them gain territories, beyond their original realm in Hesse, in Thuringia and the Frankish regions along the Main river.
After Arnulf's death, the Conradines were the only blood relatives of the new king, Louis the Child, and thus the dominant family in the kingdom. Conrad's brother Gebhard became duke of Lorraine in 903. In 906, Conrad the Elder and his son Conrad the Younger decisively defeated the rival counts of Babenberg in the battle of Fritzlar, thereby attaining supremacy in Franconia. Conrad the Elder died in the battle, but his son became duke of Franconia.
Five years later, after the death of the last Carolingian wearing the crown of East Francia in 911, Conrad was elected king as Conrad I -- instead of the West Francian (and Carolingian) king Charles the Simple, thus ending Carolingian rule in East Francia.
Conrad I had no children. Having largely failed to secure unity and order in the Empire in the face of obstinate resistance from the dukes of Swabia, Bavaria and Lorraine, Conrad, on his deathbed in December 918, persuaded his brother Eberhard, margrave and subsequently duke of Franconia, to forgo any aspiration for the crown for himself and to recommend to the Frankish nobles the election of the powerful duke of Saxony, Henry the Fowler (Henry I), as next king in order to ensure unity among the German tribes and preserve the Empire. Eberhard honored this request, and Henry was duly elected at the Reichstag of Fritzlar in 919.
With this, the Conradines reverted to the status of local princes. Conrad's brother Eberhard, the new duke of Franconia, remained loyal to the new (Saxon) king Henry and for a while (926-928) even held the troubled duchy of Lorraine in order to restore order. However, when Henry's son Otto the Great became king and emperor, Eberhard unwisely joined Arnulf of Bavaria and Thankmar, Henry's son from his first marriage, in a rebellion which ended in defeat and Eberhard's death at the battle of Andernach in 939 and the family's loss of the Franconian duchy.
In 982 the family temporarily regained the duchy of Swabia, which they had inherited in 926 but then lost again, but they held it only until 1012. In 1036, the last Conradine count died and the family (in the male line) became extinct.
