Iliaș or Ilie I (20 July 1409 – 23 April 1448) was Prince (Voivode) of Moldavia twice: from January 1432 to October 1433 and with his brother Stephen II from August 1435 to May 1443.
Iliaș faced the rebellion of his brother Stephen and several boyars, who, helped by Prince Vlad II Dracul of neighboring Wallachia, managed to dethrone him.
[5] After an indecisive battle in 1435 (at Podraga or Podagra, the present-day village of Podriga in Drăgușeni), Władysław III intervened to appease the conflict and helped institute a shared rule of the two brothers over Moldavia (with Iliaș as nominal ruler and with Stephen as lord over the southeastern part of the country—in Tecuci, Kilia, Vaslui, and Covurlui—although both shared residence in Suceava).
[6] In return, Iliaș agreed to pay an annual tribute to Poland (100 horses, 400 silk sheets, 400 oxen, 300 cartfuls of sturgeon) and to concede rule over Khotyn and Pokuttya.
Roman, Iliaș and Maria's son, remained ruler of the region, titling himself Prince of Moldavia and vassal to Władysław III; he was to be recognized as co-ruler by Stephen, and would eventually depose him.
