Lothair III, Holy Roman Emperor was a 12th-century German monarch who rose from regional Saxon nobility to the crown of the Kingdom of Germany and the imperial dignity. His reign intersected with pivotal figures and institutions of the High Middle Ages, including the Investiture Controversy, the House of Welf, the Hohenstaufen dynasty, and the papacy. Lothair's rule saw campaigns in Italy, shifting alliances with Henry V, conflicts with Frederick II's family, and significant interactions with ecclesiastical authorities such as Pope Innocent II and Antipope Anacletus II.
Born circa 1075 into the Süpplingenburg dynasty, Lothair was the son of Gebhard of Süpplingenburg and Gertrude of Brunswick. His familial links connected him to powerful Saxon houses including the House of Billung and the House of Welf through marriage ties. Lothair married Sibylla of Anjou, daughter of Fulk IV, forging cross-regional bonds with the County of Anjou and the Capetian dynasty. His daughter Gertrude of Süpplingenburg later married Henry the Proud, linking Lothair to the Dukes of Bavaria and the Counts of Northeim.
Lothair's election as king in 1125 followed the death of Henry V and a contested royal succession. The imperial electors, including magnates from the Duchy of Saxony, Duchy of Bavaria, and Archbishopric of Mainz, chose Lothair over rival candidates such as Frederick II and Conrad III (disputed claimant). Key supporters included the Saxon aristocracy and influential prelates like Adalbert of Mainz, while opposition coalesced around the Hohenstaufen dynasty. The election reflected the aftermath of the Investiture Controversy and the desire among princes to limit imperial centralization.
As King of Germany, Lothair pursued a policy balancing regional princely autonomy with royal prerogatives. He relied on alliances with the Archbishopric of Cologne, the Duchy of Saxony, and the Margraviate of Meissen to assert authority against Hohenstaufen and Welf rivals. Military engagements included confrontations with Henry the Proud and intermittent warfare in the Italian Marches and along the Rhine. Lothair granted imperial privileges to cities and monasteries such as Fulda Abbey and Magdeburg Cathedral to secure ecclesiastical backing, while negotiating with secular princes like Welf II, Duke of Bavaria.
Lothair received coronation as emperor in 1133 from Pope Innocent II after leading an expedition into Italy to support the papal cause against Antipope Anacletus II and the Roman commune. His imperial coronation reinforced the medieval concept of transalpine kingship and the reciprocal legitimization between emperor and pope established after the Concordat of Worms. In Rome he interacted with institutions such as the Lateran Palace and negotiated with cardinalate figures tied to Bernard of Clairvaux, whose influence over Cistercian networks affected papal politics. Lothair's imperial title enabled him to grant investitures and adjudicate disputes among princely litigants, though his Italian authority faced persistent local resistance.
Lothair's rivalrous relationship with the Hohenstaufen dynasty defined much of his military agenda. The election of Conrad III of Germany as an anti-king by Hohenstaufen partisans and the power base of Frederick II, Duke of Swabia fueled civil conflict in the German realms. In Italy, Lothair led expeditions to assert imperial rights in the Kingdom of Italy and to support Pope Innocent II against Roger II of Sicily and the Norman Normans. Battles and sieges included campaigns around Capua, Bari, and contested Lombard communes such as Milan. Despite initial successes, Lothair's Italian ventures proved costly and yielded limited long-term consolidation.
Domestically, Lothair sought to mediate between competing princely interests by confirming traditional privileges and granting concessions to powerful dukes like Henry the Proud and ecclesiastical rulers such as the Archbishopric of Cologne. He supported monastic reform movements tied to Cluny and the Cistercians, endorsing foundations and endowments that strengthened episcopal loyalty. Lothair also utilized appeals to imperial law traditions embodied in the Lex Salica and imperial chancery practice to legitimize his acts. His reign witnessed negotiations over territorial inheritances, investiture rights, and the jurisdictional claims of imperial courts versus ducal assemblies.
Lothair died on 4 December 1137 during a return from an Italian campaign and was buried at Aachen Cathedral. His death precipitated a dynastic contest resolved by the elevation of Conrad III of Germany from the House of Hohenstaufen, inaugurating a new phase of imperial-Hohenstaufen ascendancy. Lothair's legacy includes the temporary restoration of imperial-papal cooperation, the reinforcement of Saxon influence in royal politics, and dynastic linkages through his daughter Gertrude of Süpplingenburg that affected the subsequent Guelph–Ghibelline alignments. Historians assess his reign as a transitional episode between the Ottonian-Salian traditions and the later Hohenstaufen imperial consolidation.
