After Lothair's 1127 campaign against the Staufers had collapsed at the gates of Nuremberg, the Swabians and the Franconians declared Frederick's younger brother Conrad anti-king Conrad III. Looking for support of his kingship, in 1128 Conrad went to Italy, where he was crowned King of Italy by Anselm V, Archbishop of Milan. Lothair took advantage of Conrad's absence and weak position and resumed his attacks on the Staufers and in 1129 conquered the Staufer cities Nuremberg and Speyer. Conrad, on the other hand failed to acquire the desired assistance in Italy, and, having made no political progress, returned in 1130, which assured at least a partial victory for Lothair.
