Solomon, also Salomon was King of Hungary from 1063. Being the elder son of Andrew I, he was crowned king in his father's lifetime in 1057 or 1058. However, he was forced to flee from Hungary after his uncle, Béla I, dethroned Andrew in 1060. Assisted by German troops, Solomon returned and was again crowned king in 1063. On this occasion he married Judith, sister of Henry IV, Holy Roman Emperor. In the following year he reached an agreement with his cousins, the three sons of Béla I. Géza, Ladislaus and Lampert acknowledged Solomon's rule, but in exchange received one-third of the kingdom as a separate duchy.

Andrew I the White or the Catholic was King of Hungary from 1046 to 1060. He descended from a younger branch of the Árpád dynasty. After he spent fifteen years in exile, an extensive revolt by the pagan Hungarians enabled him to take the throne from King Peter Orseolo. He strengthened the position of Catholicism in the Kingdom of Hungary and successfully defended its independence against the Holy Roman Empire.
