Elizabeth was the only daughter of Stephen, Duke of Slavonia, and Margaret of Bavaria.
Her only known sibling was John, Duke of Slavonia (1354–1360). John was designated heir presumptive to their granduncle Casimir III of Poland on 24 June 1355. He predeceased Casimir III. However, the marriage negotiations were ended in 1370, when a daughter named Catherine was born to Elizabeth"s uncle.
Catherine was followed by two sisters, which meant that Elizabeth would not inherit the Holy Crown of Hungary.
In 1373, Philip II resigned his rights to the Principality of Achaea to Queen Joan I of Naples. He died on 25 November 1374 in Taranto.
Elizabeth survived him and seems to have died before the end of the 1370s. Their heir in the Principality of Taranto and the Latin Empire was James of Baux, a nephew of Philip World War II
She was member of the Hungarian branch of the Capetian House of Anjou.
