Béla of Hungary has attempted to conclude a peace treaty with the Holy Roman Empire.

For this purpose, shortly after his coronation, he had released all German commanders who had assisted his brother during the civil war.

However, the young German monarch's advisors had refused Béla's proposals.

In the summer of 1063, an assembly of the German princes decides to launch a military expedition against Hungary to restore young Solomon to the throne.

Béla is planning to abdicate in favor of his nephew if the latter restores his former ducatus, but he is seriously injured when "his throne broke beneath him" in his manor at Dömös.

The king—who was "half-dead", according to the Illuminated Chronicle—is taken to the western borders of his kingdom, where he dies at the creek Kinizsa on September 11, 1063.

Béla is buried in the Benedictine Szekszárd Abbey, which he had set up in 1061.

Following Béla's death, his three sons—Géza, Ladislaus and Lampert—seek refuge in Poland.

Accompanied back to Hungary by German troops, Solomon enters Székesfehérvár without resistance.

He is ceremoniously "crowned king with the consent and acclamation of all Hungary" in September 1063, according to the Illuminated Chronicle.

The same source adds that the German monarch "seated" Solomon "upon his father's throne", but did not require him to take an oath of fealty Solomon's marriage with Henry IV's sister, Judith—who is six year older than her future husband—also takes place on this occasion.

Judith, along with the Queen Mother Anastasia, becomes one of her young husband's principal advisors.
