Henry the Lion

Henry the Lion was a pivotal figure of the High Middle Ages in Germany, ruling as both Duke of Saxony and Duke of Bavaria. His vast territorial power, centered on his base at Brunswick, brought him into direct conflict with the imperial authority of his cousin, Frederick I Barbarossa. His eventual downfall after refusing military support for the Italian campaign led to his dispossession and exile, though his legacy endured through his descendants and the enduring influence of the House of Welf.

Early life and inheritance

Born around 1129, he was the son of Henry X, Duke of Bavaria and Gertrude of Süpplingenburg, the sole heir of Emperor Lothair III. Following his father's death in 1139, the young Welf heir was initially deprived of his patrimony by the new Hohenstaufen king, Conrad III, who granted the Duchy of Saxony to Albert the Bear. Through persistent negotiation and shifting political fortunes, he was formally invested with Saxony in 1142, restoring a significant portion of his family's influence. His mother's connections to the German monarchy and the legacy of the Salian dynasty were crucial in this recovery, setting the stage for his future ambitions.

Rule in Saxony and Bavaria

His rule transformed northern Germany, where he aggressively expanded his authority through a combination of warfare, colonization, and dynastic policy. He campaigned extensively against the Slavic Obotrite confederation, consolidating his hold over territories like Mecklenburg and promoting Christian settlement east of the Elbe River. In 1156, through the mediation of Frederick Barbarossa, he regained the Duchy of Bavaria, though its southeastern march was severed to create the new Duchy of Austria for the House of Babenberg. He made Brunswick his principal residence, fostering its development and founding the Cathedral of St. Blasius there, while his marriage to Matilda of England forged a prestigious alliance with the House of Plantagenet.

Conflict with Emperor Frederick Barbarossa

The alliance with his cousin Frederick Barbarossa gradually deteriorated due to his autonomous and powerful position, which challenged the emperor's vision of imperial supremacy. Tensions came to a head in 1176, when he refused to provide contingent support for Barbarossa's campaign in Lombardy, a critical moment in the Wars of the Guelphs and Ghibellines. This refusal contributed to the emperor's decisive defeat at the Battle of Legnano by the Lombard League. Perceiving this as a breach of feudal obligation, Barbarossa initiated a series of judicial proceedings against him at the Imperial Diet, culminating in the imperial ban and the confiscation of his fiefs.

Fall and exile

Outlawed and facing a coalition of hostile princes, including his long-time rival Albert the Bear, he was militarily defeated. The Diet of Gelnhausen in 1180 formally deposed him, stripping him of the duchies of Saxony and Bavaria. Saxony was broken up, with its western portion granted to Cologne and the eastern rump to Bernard of Anhalt, while Bavaria was awarded to Otto of Wittelsbach. Forced into exile, he sought refuge at the court of his father-in-law, King Henry II, in Normandy and later in Anjou, spending several years away from his German lands.

Later years and legacy

He was allowed to return to Brunswick in 1185, but his remaining power was confined to his allodial possessions around the city. He undertook a pilgrimage to the Holy Land in 1192, visiting the Kingdom of Jerusalem. He died in 1195 and was buried in the Brunswick Cathedral he had founded. His legacy was carried on by his sons: Otto IV became the only Welf Holy Roman Emperor, and William founded the Lüneburg branch of the Welfs. The enduring conflict between the House of Welf and the Hohenstaufen dynasty shaped Imperial politics for generations, and his patronage left a lasting architectural and cultural imprint on Lower Saxony.
