Henry II Yazomirgott (German Heinrich II Jasomirgott;. 1107-13 January 1177) - Margrave of Austria (1141-1156), Duke of Austria (c 1156), Palatine Rhine (1140-1141), as well as the name of Heinrich the XI, Duke of Bavaria (1141-1156), of the Babenberg dynasty.
Henry II was the son of Leopold III and St. Agnes, daughter of the Emperor Henry IV. In 1140 he became the Palatine Rhine, however, after the sudden death of his elder brother Leopold IV in 1141, he returned to Bavaria.
Having inherited from his brother Welf of conflict with the Bavarian throne, Henry II was forced at the beginning of his reign defending their possessions from Welf troops and to suppress the uprising of their supporters in Bavaria. In 1147 Austria invaded the Hungarian army, which, however, was defeated by Henry II in the Battle of Leith river. Having won over the Hungarians, the Duke went on a crusade, during which he married a Byzantine princess Theodora Comnenus. On his return to Bavaria again, war broke out with Welf. The situation worsened in 1152, after the accession to the throne of the Holy Roman Empire of Frederick I, striving for a peaceful resolution of the conflict between the Welf and Babenberg forces to consolidate the empire to conquer Italy.
In 1156, Emperor Frederick I gave the head of Bavaria Welf Henry the Lion House, and as compensation for Henry II issued a special patent of the Austrian Babenberg possessions, known as Privilegium Minus. This document Austria elevated to a duchy, proclaimed its complete independence from Bavaria and establishes the right of succession to the Austrian throne dynasty Babenberg both in male and in the female line, as well as the appointment of the Duke his successor (the only one of its kind right among all the German principalities) . Thus it was laid the foundation of the new Austrian state and set the stage for the expansion of Austria`s independence.
At the end of his reign, Henry II took part in the campaigns of Emperor Frederick I against Italian cities and rebellious German princes. In 1166 Duke led the negotiations on behalf of the emperor and Byzantium. In the regional arena Henry II collaborated with the coalition Carinthia against Czech Republic, Hungary and Styria. Despite the successful invasion of Styria, in 1176 the Czech-Hungarian troops defeated the Austrians and devastated the valley of the Danube.
In 1145 Henry II moved the capital of Austria Vienna. Since his reign began the rapid development of the city. In 1147 the construction of St. Stephen`s Cathedral in Vienna, which to date remains one of the main attractions of the capital was completed.
The origin of the nickname of Henry II - Yazomirgott (Jasomirgott) - is not clear. According to one theory, it goes back to the Arabic language and is associated with the Duke in the crusade. According to another version, it is a truncated phrase Ja so mir Gott helfe (if God helped me).
