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 King Henry IV of Germany, 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.
