Lampert of Hungary

Who was Lampert of Hungary?

Lampert was a member of the Árpád dynasty; Duke of one-third of the Kingdom of Hungary.

Lampert was the third son of the future King Béla I of Hungary and his Polish wife. He was born in Hungary when his father had already returned from Poland and had already received the Tercia pars regni in appanage from his brother, King Andrew I of Hungary.

Following the death of King Béla I, Lampert and his elder brothers fled to Poland from their cousin, King Solomon, who had returned to the kingdom with the military assistance of the Emperor Henry IV. When the German armies left the kingdom shortly afterwards, the three brothers returned followed by the troops King Bolesław II, their maternal cousin, provided them. The parties, however, wanted to avoid the civil war; therefore they accepted the mediation services of the bishops, and they made an agreement in Győr. Under the agreement, Lampert and his brothers accepted King Solomon's rule, and they received their father's former duchy, i.e., the Tercia pars regni.

In the next years, the three dukes collaborated successfully with King Solomon, but afterwards new conflicts emerged among them. The three dukes rebelled against the king and the eldest of them, Géza, was proclaimed king following their victory over Solomon's troops. When King Géza I died his brother, Ladislaus, ascended the throne.
