Henry II (; 1107 – 13 January 1177), called Jasomirgott, a member of the House of Babenberg, was Count Palatine of the Rhine from 1140 to 1141, Duke of Bavaria (as Henry XI) and Margrave of Austria from 1141 to 1156, and the first Duke of Austria from 1156 until his death. Family Henry was the second son of Margrave Leopold III of Austria, the first from his second marriage with Agnes of Waiblingen, a sister of the last Salian emperor, Henry V. Leopold himself was expected to stand as a candidate in the 1125 election as king of Germany; nevertheless, he renounced in favour of his step-son (and Henry's half-brother), the Hohenstaufen duke Frederick II of Swabia, who eventually lost against Lothair of Supplinburg. Among Henry's younger brothers were Bishop Otto of Freising and Archbishop Conrad II of Salzburg. His sister Judith became the wife of Marquess William V of Montferrat. Henry's nickname, Jasomirgott, was first documented during the 13th century in the form of Jochsamergott, the meaning of which is unclear. According to popular etymology, it is derived from the Middle High German form of the oath joch sam mir got helfe (meaning: "Yes, so help me God"). Reign When Margrave Leopold III died in 1136, he was succeeded by his third-born son Leopold IV, probably because Henry already administered the Rhenish possessions of his mother's now-extinct Salian dynasty. In April 1140, the Hohenstaufen king Conrad III of Germany enfeoffed him with the County Palatine of the Rhine, which he ruled for only a short time as he was appointed Bavarian duke and margrave of Austria when his younger brother Leopold IV unexpectedly died in October 1141. Leopold had received the Duchy of Bavaria in 1139, after King Conrad had deposed Duke Henry the Proud in the course of the dispute between the Welf and Hohenstaufen dynasties. Henry took his residence in the Bavarian capital of Regensburg (Ratisbona). In May 1142 he married Gertrude, daughter of Emperor Lothair and widow of Henry the Proud. She died after less than one year, giving birth to her only child with Henry. The duke remained a loyal follower of the Hohenstaufens and in May 1147 accompanied King Conrad on the Second Crusade. When they suffered a disastrous defeat at the Battle of Dorylaeum against the Seljuk Turks in October, Henry narrowly escaped together with Conrad's nephew, young Frederick Barbarossa. Later on,
