Anno II was a powerful 11th-century prelate who served as the Archbishop of Cologne from 1056 until 1075. Born into the Steusslingen family in Swabia, he rose through the ecclesiastical ranks to become a key political figure in the Holy Roman Empire. During the minority of Emperor Henry IV, Anno acted as a regent, notably leading a coup to seize control from the Empress Agnes. He was a significant influence in imperial politics, a supporter of certain papal claimants, and a founder of several influential monasteries.
