Henry the Lion
Rule

Henry the Lion did not relinquish his claims to his inheritance, and Conrad returned Saxony to him in 1142. A participant in the 1147 Wendish Crusade, Henry also reacquired Bavaria by a decision of the new emperor, Frederick Barbarossa, in 1156. However, the East Mark was not returned and became the Duchy of Austria.

Henry was the founder of Munich (1157) and Lübeck (1159); he also founded and developed numerous other cities in Northern Germany and Bavaria, a.o. Augsburg, Hildesheim, Stade, Kassel, Güstrow, Lüneburg, Salzwedel, Schwerin and Brunswick. In Brunswick, his capital, he had a bronze lion, his heraldic animal, erected in the courtyard of his castle Dankwarderode in 1166—the first bronze statue north of the Alps. Later, he had Brunswick Cathedral built close to the statue.

In 1147, Henry married Clementia of Zähringen, thereby gaining her hereditary territories in Swabia. He divorced her in 1162, apparently under pressure from Emperor Frederick Barbarossa, who did not cherish Guelphish possessions in his home area and offered Henry several fortresses in Saxony in exchange. In 1168, Henry married Matilda (1156–1189), the daughter of King Henry II of England and Duchess Eleanor of Aquitaine, and sister of King Richard I of England.

Henry faithfully supported Emperor Frederick in his attempts to solidify his hold on the Imperial Crown and his repeated wars with the cities of Lombardy and the popes, several times turning the tide of battle in Frederick's favor with his Saxon knights. During Frederick's first invasion of northern Italy, Henry took part, among the others, in the victorious sieges of Crema and Milan.

In 1172, Henry took a pilgrimage to Jerusalem (June–July), meeting with the Knights Templar and Knights Hospitaller, and spending Easter of that year in Constantinople. By December 1172, he was back in Bavaria and, in 1174, he refused to aid Frederick in a renewed invasion of Lombardy because he was preoccupied with securing his own borders in the east. He did not consider these Italian adventures worth the effort, unless Barbarossa presented Henry with the Saxon imperial city Goslar: a request Barbarossa refused.
