Géza held the title of Duke of Hungary — not king — during this period, ruling the eastern third of the kingdom as appanage while his brother Salomon held the crown. The arrangement was formalized after the Peace of Győr in 1064, ending a dynastic civil war between the sons of Béla I and the sons of András I. Coins struck in Géza's name as crown prince are consequently rare: a subordinate duke issuing his own coinage was already an assertion of near-royal status, and the political friction that generated these pieces ended when Géza seized the throne outright in 1074.
