After a series of armed conflicts, Rudolf succumbed to his injuries after his forces defeated Henry's in the Battle on the Elster.

The Saxon revolt was a civil war fought between 1077 and 1088, early in the history of the Holy Roman Empire. The revolt was led by a group of opportunistic German princes who elected as their figurehead the duke of Swabia, Rudolf of Rheinfeld, who became the anti-king. Rudolf was a two-way brother-in-law of the young Henry IV, Holy Roman Emperor, who had been crowned at the age of six and had taken the reins of power at age sixteen. The Great Revolt followed the Saxon Rebellion of 1073–75.
The Bohemian Revolt was an uprising of the Bohemian estates against the rule of the Habsburg dynasty that began the Thirty Years' War. It was caused by both religious and power disputes. The estates were almost entirely Protestant, mostly Utraquist Hussite but there was also a substantial German population that endorsed Lutheranism. The dispute culminated after several battles in the final Battle of White Mountain, where the estates suffered a decisive defeat. This started re-Catholisation of the Czech lands, but also expanded the scope of the Thirty Years' War by drawing Denmark and Sweden into it. The conflict spread to the rest of Europe and devastated vast areas of Central Europe, including the Czech lands, which were particularly stricken by its violent atrocities. Directories were appointed.

He was the son of Henry III, Holy Roman Emperor—the second monarch of the Salian dynasty—and Agnes of Poitou. After his father's death on 5 October 1056, Henry was placed under his mother's guardianship. She made grants to German aristocrats to secure their support. Unlike her late husband, she could not control the election of the popes, thus the idea of the "liberty of the Church" strengthened during her rule. Taking advantage of her weakness, Archbishop Anno II of Cologne kidnapped Henry in April 1062. He administered Germany until Henry came of age in 1065.
Henry II, also known as Saint Henry the Exuberant, Obl. S. B., was Holy Roman Emperor from 1014. He died without an heir in 1024, and was the last ruler of the Ottonian line.

The Lutici or Liutizi were a federation of West Slavic Polabian tribes, who between the 10th and 12th centuries lived in what is now northeastern Germany. Four tribes made up the core of the federation: the Redarians, Circipanians (Circipani), Kessinians and Tollensians (Tholenzi). At least in part, the Lutici were a continuation of the Veleti. In contrast to the former and the neighboring peoples, the Lutici were not led by a Christian monarch or duke, rather power was asserted through consensus formed in central assemblies of the social elites, and the Lutici worshipped nature and several deities. The political and religious center was Radgosc.

A princely rebellion or princely revolt is an intrastate armed conflict by a prince against a reigning monarch of his own family, the ruling dynasty. A prince may rebel against a well-established monarch in order to seize the throne for himself immediately, to ensure his supposed right to sit on the throne in the future, or to secure other rights, privileges or interests such as appanages, alliances or sources of revenue that the monarch allegedly encroached upon, or failed to deliver or guarantee.
