László IV ruled Hungary — and by extension its Slavonian province — through near-constant civil war, factional rebellion, and a papally-mandated crusade against his own Cuman allies, with whom he was personally and politically entangled in ways that scandalized the Hungarian nobility and the Church simultaneously. He was assassinated in 1290 by Cumans while still in his twenties. The Slavonian denier series issued under his name continued a regional minting tradition distinct from the royal Hungarian issues, with Slavonia maintaining its own banovac coinage infrastructure throughout the 13th century.
