The First Battle of Langensalza was fought on June 9, 1075 between forces of German King Henry IV and several rebellous Saxon individuals on the River Unstrut. The battle was a complete success for Henry, resulting in the subjugation of Saxony shortly before the Investiture Controversy commenced.

Background

From the start of his reign, Henry had suffered numerous setbacks in Saxony. Attempts to restore royal rights over the forests were not received well by the Saxon freedmen, and efforts to extend the crownlands in general as well as the increased demands laid upon the fisc, were opposed. A policy of building castles, continued from the time of his father, implemented by the King fostered resentment among multiple groups. In particular, the Harzburg became a symbol of Imperial tyranny and impeding on traditional Saxony rights. Like his father, Henry desired to set Goslar as the fixed capital of the German Kingdom. Henry had already had to put down a rebellion led by Otto of Nordheim and Magnus Billung (1070–1071). The King kept Magnus prisoner at the Harzburg, even after the latter succeeded his father to the Duchy of Saxony in 1072. This heightened tensions between the royal court and the Saxons; Magnus' subsequent release in exchange for seventy Swabians captured in Lüneburg did little to provide a thaw in relations. In anger, the King rejected several Saxon petitions for redress.

In 1073 several bishops and nobles organized a resistance. Several castles were besieged, and the King was forced to escape from the Harzburg to Hessewech . In February 1074 he proceeded to Gerstungen , where the insurrection, numbering twice the size of his forces, met him; he agreed to several concessions, reasoning that the Saxons would break their end of the deal eventually. The freedmen, who felt betrayed by the nobles due to the peace, sacked the Harzburg in a frenzy, destroyed the castle, and committed such acts of sacrilege (tossing the bones of members of the royal family, along with those of an abbot and St. Anastasius ) that they shocked the local population and the religious authorities. Henry used the destruction as a pretext for renewed hostilities. He gained the support of several bishops, the lower feudality and city burghers. While Henry was conducting a campaign against the Magyars to the side, papal legates were attempting to create support for the Saxon rebels. In 1075 Otto of Nordheim , together with the count palatine in Saxony and Bishop Burckhardt of Halberstadt openly declared their hostility, using Henry's violations of the Gerstungen treaty as an excuse. They gained many Saxon and Thuringian freedmen, but many nobles and peasants did not join.

The King made camp in Bredingen , and manage to gain the defections of some lower Saxon nobles with promises to listen to their grievences. In June, he moved to Langensalza.

The Battle

Henry's move to Langensalza put him closer to the Saxon encampment. The two sides met for battle at Homburg on June 9.

The Saxon army contained several thousand men, but in typical Saxon tradition, most of them were on foot. Their ranks consisted of nobles and their vassals, along with freedmen and some serfs. Many of them were poorly trained. On the other hand, Henry's army was well-organized in typical feudal fashion, with a large amount of mounted warriors.

The engagement that followed was less of a battle than a rout. A charge by the Swabians under Duke Rudolf almost instantly destroyed the Saxon center. The leaders took to their horses and fled, but the foot soldiers were slaughtered. It was reported that several thousand died when they drowned in the Unstrut. Many spoils were gained by Henry's army.

The Aftermath

The defeat was stunning. It shocked the Saxons, and the supporters of the rebellion became frantic. The Archbishop of Mainz threatened excommunication against the Thuringians in order to gain funds to finance the insurrection. Unfortunately, Henry and his army ravaged the Saxon and Thuringian countryside, bringing starvation. The Archbishop of Magdeburg eventually conceded and requested the terms the King would hold the rebels to. Henry demanded a short imprisonment for all the leaders, as well as confiscation of their fiefs and their redistrubution among loyal Imperial partisans. As harsh as the terms were, the complete victory Henry gained at Langensalza convinced them to accept. In a humiliating gesture, the rebel bishops, nobles and peasants walked barefoot between the ranks of the King's army and submitted to him. The King then convened a meeting of princes at Goslar on Christmas to determine the future of Saxony; he ended up freeing Otto of Nordheim and making him his viceroy to Saxony. Henry considered the Saxon question settled, but the Investiture conflict would quickly undo the peace.
