On 17 July 1440 Vladislaus, king of Poland, was crowned despite continuing disputes.[5] John Hunyadi aided Vladislaus's cause by pacifying the eastern counties, gaining him the position of Nádor of Transylvania and the corresponding responsibility of protecting Hungary's southern border. By the end of 1442, Vladislaus had secured his status in Hungary, and rejected an Ottoman proposal of peace in exchange for Belgrade.[2]
