Battle of Pressburg

Battle of Pressburg, or Battle of Bratislava refers to a battle fought on July 4, 907, during which the Bavarian army was defeated by the Hungarians.

The battle
Margrave Luitpold of Bavaria built up his army and attempted to score a decisive victory against the Hungarians, who already formed an important state in Europe. The German army supposedly included more than 100,000 soldiers, which is almost certainly an exaggeration typical of the time. Árpád's army the Hungarian was only around 30-35,000. Few medieval armies are known to have exceeded 10,000. The German army, consisting of three battle groups, was crushed and a large part of Luitpold's army was destroyed. The German casualties included the Margrave, Archbishop Theotmar, three bishops and 35 counts.

Location
The precise location of this battle is not known. The only contemporary source mentioning a location of the battle are the Annales Iuvavenses maximi (Annals of Salzburg); however, the reliability of these annals is questionable, as they survive only in fragments copied in the 12th century. They state that the battle took place in the vicinity of Brezalauspurc, the castle of Duke Brazlavo, located west of Lake Balaton. Some interpretations equal Brezalauspurc with modern-day Bratislava or east of Vienna while others claim that it was Urbs Paludarum - Brazlavo's burg near Lake Balaton in Pannonia.

Aftermath
After the Battle, the Hungarians reoccupied present-day eastern Austria up to the River Enns, began pillaging the surrounding regions. The Hungarian threat to Germany persisted until 955 when Otto I the Great won a decisive victory at the Battle of Lechfeld, which brought internal stability to German lands. However after the battle (907) Germans could not attack Hungary for 100 years.
