Conrad III of Germany was a member of the Hohenstaufen dynasty who ruled as King of Germany from 1138 until his death in 1152. A younger son of the Swabian ducal line, he was elevated to the kingship after the death of Lothair II and his election marked the ascendancy of the Hohenstaufen within the politics of the Holy Roman Empire. Conrad’s reign is noted for conflicts with rival dynasties such as the Welfs, interventions in Italian affairs and an ill-fated role in the Second Crusade that shaped perceptions of his rule.

Early life and background

Conrad was born circa 1093 into the House of Hohenstaufen, son of Frederick II, Duke of Swabia and Judith of Bavaria. His elder brother was Frederick I, Duke of Swabia and his younger brother later became Frederick I Barbarossa. Conrad’s family was intertwined with other major houses including the Salian dynasty, the Welfs, and the Babenberg margraves of Austria. Educated in the milieu of Swabian court culture, he held the ducal title of Duke of Franconia and engaged in regional politics involving the Bishopric of Bamberg, the Archbishopric of Mainz, and the counts of Leiningen and Zähringen.

Rise to power and election as King

After the death of Henry V, Holy Roman Emperor and the contested succession that led to the reign of Lothair II, the German princes sought a candidate to counterbalance Lothair’s supporters. The death of Lothair in 1137 precipitated a contested royal election in which Conrad, supported by his brother Frederick II and the influential Count of Flanders allies, secured the throne at the 1138 assembly at Coblenz and Frankfurt. His election displaced the claims of the Welf candidate Henry the Proud, duke of Bavaria and Saxony, leading to protracted feuds. Key electors including the Archbishop of Cologne, the Bishop of Bamberg, and secular princes such as the Margrave of Brandenburg played pivotal roles in endorsing Conrad’s kingship.

Reign and governance (1138–1152)

Conrad’s kingship focused on consolidating Hohenstaufen authority across the Holy Roman Empire amidst persistent resistance from the Welf faction led by Henry the Proud and later Henry the Lion. He sought alliances with regional lords like the Counts of Savoy and the Margraves of Meissen while negotiating with ecclesiastical magnates such as the Pope’s legates and the Archbishopric of Mainz. Conrad invested family members in key territorial offices, granting the duchies of Swabia and Franconia to Hohenstaufen loyalists and attempting to limit the power of rivals in Bavaria and Saxony. His rulings in imperial assemblies at Regensburg and Nuremberg addressed disputes involving the Duchy of Bohemia, the County of Holland, and the Margraviate of Tuscany.

Italian campaigns and relations with the Papacy

Conrad continued the long-standing imperial involvement in Italy and the investiture tensions with the Papacy. Early in his reign he attempted to assert imperial prerogatives in the Kingdom of Sicily and the March of Ancona while negotiating with papal officials including Pope Innocent II and his successor Pope Eugenius III. Conrad’s agents intervened in municipal disputes among Roman families and in the politics of the Norman rulers of southern Italy, bringing him into intermittent conflict with the papal curia and with northern Italian communes such as Milan and Pavia. Diplomacy and limited military forays aimed to secure Hohenstaufen influence over appointments to episcopal sees and march lordships, yet persistent resistance in Rome and from the Guelph supporters of the Papacy complicated his objectives.

Participation in the Second Crusade

In 1147 Conrad responded to calls for a crusade following the fall of Edessa by joining the Second Crusade. He led a large German contingent that marched across Byzantium and through the Balkans, coordinating with other crusader contingents including those of Louis VII of France and the Kingdom of Jerusalem. Tensions with Byzantine Emperor Manuel I Komnenos over logistics and distrust of imperial intentions hampered operations. Conrad’s force suffered heavy losses en route and his leadership was criticized after the failed siege of Damascus in 1148, a campaign that also involved commanders such as Amalric I of Jerusalem and Raymond of Poitiers. On return to Germany in 1149, Conrad’s prestige was weakened, and his crusading experience influenced subsequent Hohenstaufen policy toward eastern affairs and relations with Byzantium.

Family, dynastic policies, and legacy

Conrad married Gertrude of Sulzbach and his children included Bertha of Sulzbach (later linked to Byzantine marriage politics) and other offspring who secured alliances with dynasties such as the Comnenus and Norman houses. He formalized Hohenstaufen claims that paved the way for his nephew Frederick I Barbarossa’s eventual imperial coronation. Conrad’s dynastic policies favored marital networks with the Babenberg and Welf adversaries when advantageous, and he fostered Hohenstaufen consolidation in Swabia and Franconia. Despite military setbacks in Italy and during the Second Crusade, his reign established the Hohenstaufen as a central force in mid-12th-century imperial politics. Conrad died at Bamberg on 15 February 1152 and was succeeded by Frederick I, leaving a mixed legacy of territorial gains, dynastic entrenchment, and contested royal authority.
