Stephen II of Hungary

Stephen II (Hungarian: II. István; Croatian: Stjepan II.; Slovak: Štefan II.; 1101 – early 1131), King of Hungary and Croatia, ruled from 1116 until 1131. His father, King Coloman, had him crowned as a child, thus denying the crown to his uncle Álmos. In the first year of his reign, Venice occupied Dalmatia and Stephen never restored his rule in that province. His reign was characterized by frequent wars with neighbouring countries.
