Lothair II of Supplinburg (1075–1137), was the Duke of Saxony (1106), King of Germany (1125), and Holy Roman Emperor from 1133 to 1137. He was the son of Count Gebhard of Supplinburg. He is sometimes referred to as Lothair III.
Rise to Power
After years of purchasing lands or gaining them via marriage alliances throughout the Duchy of Saxony, Lothair gained the domains of the Billung, Nordheim and Brunswick families and became one of the dominant landowners in the northern duchy. He was next granted the duchy in 1106 by Emperor Henry V in exchange for his hlep against Henry's father, Henry IV, Holy Roman Emperor. Emboldened by the promotion, Lothair revolted against Henry's rule and denied Henry's ability to lord over Saxony during the Investiture Controversy. In 1115 his forces defeated those of the Emperor's in the Battle of Welfesholz.
When Henry died in 1125, Lothair was viewed by the Archbishop of Mainz as a perfect candidate. As an extensive landowner, he brought power to the table, but he was old (slightly over fifty years of age) had no heirs, potentially making him malleable for the nobility. He was therefore elected to the German throne after a contentious power stuggle with Frederick II, Duke of Swabia, ruler of the House of Hohenstaufen. His election was notable in that it marked a departure from Imperial policy under the Salians; the concept of hereditary succession was broken and the new king accepted confirmation of his position by the pope.
A campaign undertaken in the same year against Bohemia ended in defeat, making for a less than great start by Lothair. Among those imprisoned by the Bohemians was Albert of Ascanian, future Margrave of Brandenburg.
Dispute with the Hohenstaufens
During his reign, a succession dispute broke out between the houses of Welf and Hohenstaufen, the latter which was led by Frederick II and his brother Duke Conrad of Franconia. The Hohenstaufen, in addition to claiming the private Salian lands which clearly fell to them, also claimed all of the crown lands gained under Henry IV and Henry V. Lothair's attempts to seize the crown lands following approval from a group of nobles meeting in Regensburg provoked Hohenstaufen reaction. Frederick of Swabia was placed under the imperial ban, Conrad was deprived of Franconia, and the rectorate of Burgundy passed to Conrad of Zahringen.
The Hohenstaufen, who had the support of their own lands plus support in many imperial cities, Austria, and much of Lower Lorraine, raised Conrad as antiking Conrad III. In 1128 he was crowned King of Italy by the Archbishop of Milan. Lothair took advantage of Conrad's expidition into Italy and his lack of resources by attacking the Staufens in Germany. Nürnberg and Speyer, two strong cities in support of the opposition, fell in 1129. Conrad's failure to make anything of his position in Italy, causing him to return in 1130 without anything to show for it, assured at least a partial victory for the king.
Relations with the Papacy
In the double papal election of 1130, both sides campaigned for Lothair's support. The king had an opportunity to take advantage of the situation and reassert Imperial control over the papacy, but choosing instead to deal with the Staufen resistance, he let his inferiors make the decision. Anacletus II offered Lothair the Imperial crown, but in the end Innocent II gained his support, and he promised to escort the new pope back to Rome. In 1131 the two met at Liege, where the king demonstrated subservience to the pope, and his request that investiture be restored to him was ignored. He also agreed to assist Innocent against King Roger II of Sicily, an ally of Anacletus.
The force Lothair took with him into Italy in 1132 was not strong, due to his leaving troops in Germany to prevent the Hohenstaufen from revolting. Carefully avoiding the cities, which were hostile, he reached Rome in 1133, which was mostly held by Anacletus. As St. Peter's was closed to them, Innocent instead crowned Lothair as emperor in the Lateran. The emperor continued giving little to know resistance against papal interference on his power; he even ignored a bull by Innocent which stated that the emperor's authority derived from him. He also recognized papal claims to the Matildine lands (formerly owned by Countess Matilda), in exchange receiveing those lands as fiefs.
Campaign against Sicily
Returning to Germany, he set out to create peace. The Hohenstaufen brothers, falling short on resources, were compelled to submit. The Reichstag in Bamberg in 1135 pardoned the two brothers and restored them to their lands. In return, they recognized Lothair as emperor and promised to assist him in another Italian campaign, and a ten-year Landpiece was declared.
In 1136, at the insistance of Innocent and Byzantine Emperor John II Comnenus, the campaign began, directed against Roger of Sicily. Two main armies, one led by Lothair, the other by Henry the Proud of Bavaria, entered Italy. Advancing deep into the southern part of the peninsula, the two armies met at Bari, and continued further south in 1137. Roger offered to grant Apulia as a fief of the Empire to one of his sons and give another son as a hostage; generous terms which Lothair refused after being pressured by Innocent.
The German troops, however, were adamant against campaigning during the hot summer, and revolted. The emperor, who had hoped for the complete conquest of Sicily, instead seperated Capua and Apulia from Roger's kingdom and gave them to Roger's enemies. Innocent, however, protested, claiming Apulia fell under papal claims; the two eventually jointly enfeoffed the duchy to Rainulf of Alife. Lothair turned north, but died while crossing the Alps in December 1137. Shortly beforehand, he gave his Tuscan Matildine lands to Henry the Proud of Bavaria, and his last acts were to give the Duchy of Saxony and the imperial regalia to him. Unfortunately, the kingship ended up in the hands of the Hohenstaufen, destroying Lothair's hopes for a powerful Welf monarchy. He is entombed in the monastery church of Königslutter.
Actions in the North and East
The emperor's most long-lasting contribution to Germany came from his actions in the north and east. Being a Saxon, he gave more attention to the region than previous emperors. Even before becoming German king, he had given control of ] and Stormarn to Adolf I of Schauenburg. In 1134 he appointed the Ascanian Albert to the March of Brandenburg. In 1136 he appointed Conrad the Great of Wettin, Margrave of Meissen, to Lausitz, uniting the two. In addition, he petitioned to expand the rights of the Archbishops of Bremen and Magdeburg in the area. King Eric II of Denmark was made a vassal of the emperor in 1135, becoming a member of the Reichstag. Successful diplomatic intervention by Lothair in ending war between Poland and Hungary resulted in the Polish king's submission and his payment of tribute that was long overdue. In addition, the Polish king was given Pomerania and Rügen as fiefs of the Empire.
