Ulrich of Augsburg was a 10th-century German prince-bishop who served the See of Augsburg. Born in 890, he was educated at the monastery of St. Gall before entering the service of the Ottonian dynasty. As a leader in the Holy Roman Empire, he was known for his loyalty to Emperor Otto the Great and his efforts to reform the clergy. He is notably remembered for his courageous defense of Augsburg against Magyar invaders, which helped secure time for imperial forces to arrive and eventually defeat the attackers.
