Béla attempted to conclude a peace treaty with the Holy Roman Empire. For this purpose, shortly after his coronation, he released all German commanders who had assisted his brother during the civil war. However, the young German monarch's advisors refused Béla's proposals. In the summer of 1063, an assembly of the German princes decided to launch a military expedition against Hungary to restore young Solomon to the throne. Béla was planning to abdicate in favor of his nephew if the latter restored his former "ducatus", but he was seriously injured when "his throne broke beneath him" in his manor at Dömös. The Kingwho was "half-dead", according to the "Illuminated Chronicle"was taken to the western borders of his kingdom, where he died at the creek Kinizsa on 11 September 1063. Béla was buried in the Benedictine Szekszárd Abbey, which he had set up in 1061. Following Béla's death, his three sonsGéza, Ladislaus and Lampertsought refuge in Poland, and Solomon ascended the throne.
