A German invasion of Hungary took place in August–September 1063, interfering in a dynastic conflict in the Kingdom of Hungary. Solomon, assisted by his brother-in-law Henry IV of Germany, decided to return to Hungary in order to his restoration to the Hungarian throne against his usurper uncle Béla I. Prior to that, Henry IV refused Béla's proposals to conclude a peace treaty with the Holy Roman Empire. German troops invaded Hungary in August 1063. Béla died in an accident unexpectedly and the German army entered Székesfehérvár. Henry installed Solomon on the throne.
