Battle of Pressburg Begins
East Francia sought to reverse Hungarian control of lands east of Bavaria after Magyar groups had established themselves in the Carpathian Basin. A large Bavarian-led expedition advanced along both banks of the Danube toward a location recorded as Brezalauspurc, whose precise identification remains debated. Fighting conventionally dated from July 4 to July 6 ended with Hungarian forces destroying much of the East Frankish army. Margrave Luitpold, Archbishop Theotmar of Salzburg, and numerous Bavarian nobles and clergy were killed. Because fuller accounts were written centuries later, the battle's detailed sequence and location remain subjects of historical reconstruction.
