In 1058, Solomon, son of Andrew I of Hungary was betrothed to Judith, daughter of the Emperor Henry III.

In Hungary, however, a party opposed to such close ties with Germany arose, led by Béla, Andrew's brother.

Andrew was killed in a subsequent charge of the Hungarian cavalry, but the Margrave William and a certain Bavarian named Poto fought from sunset until sunrise so that "the deeds of the very bravest of men of former times seem small in comparison.
