camp and formally requested and received the fief of Bohemia. Peace was restored, prisoners set free and although the winner of the battle had submitted himself to the losing side, he secured full legitimacy and lasting prestige. Dispute with the Staufers Having both Saxon and Bavarian ancestry, the Supplinburg dynasty was a political opponent of the Salian dynasty and the House of Hohenstaufen. Disputes arose with Duke Frederick II when he refused to hand over property to Lothair, which the king considered to be royal property, the Staufer on the other hand argued, that it belonged to the Salian heritage. The contentious assets had long been administered together with other Salian domestic estates, their origin was hard to determine and difficult to separate. Lothair advocated the principle that all of the assets in question had now become imperial properties due to the extinction of the Salian dynasty. The first armed engagements between Lothair and the Staufer took place as early as 1125 and increased in the years that followed. Lothair, with the approval obtained at a meeting of the princes in Regensburg, attempted to seize the crown lands, which provoked a Staufer reaction. Lothair then isolated Frederick II as he placed him under Imperial ban and withdrew the Franconian ducal fief from Conrad. 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.

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. Lastly Lothair, in order to prevent the loss of Burgundy to a power hostile to the empire, appointed his loyal ally Conrad I, Duke of Zähringen as Rector of the Principatus Burgundiaey. Domestic policies in the Northeast Emperor Lothar's policies and actions in the northern and eastern estates of the kingdom would have the longest-lasting impacts. As a Saxon by birth, he was certainly more focused on that region than previous and future monarchs. He already pursued active
