# bio (long form, separated for readability)
bio: |
  Ladislaus became King of Hungary at nine in 1272, still a prisoner of the lord who'd kidnapped him two years earlier, his father dead and rival barons carving the realm into fiefs. Declared of age in 1277, he led forces that helped Rudolf I crush Ottokar II at Marchfeld in 1278, but back home royal authority was smoke. When a papal legate demanded he suppress the pagan Cumans — his mother's people — Ladislaus sided with the steppe clans and earned excommunication; many Cumans left Hungary anyway. He beat back a Cuman invasion in 1282 and survived Mongol incursions in 1285, but suspicion stuck that he'd invited the latter himself. By 1286 he'd locked his wife away and roamed the countryside with Cuman mistresses, unable to check the magnates or bishops. Pope Nicholas IV was preparing a crusade against him when three Cumans killed him in July 1290.
