In my research, I examine the diplomatic relations between Venice and the Kingdom of Hungary during the Jagiellonian era. Through Venetian narrative sources, my study presents the anti-Ottoman war of 1501–1503, a period during which both parties were engaged in conflict against the Sultan. In my work, I devote particular attention to the writings of Girolamo Priuli, a diarist who is less known to the international scientific community. Hailing from a merchant family and working as a banker, Priuli was a member of the Venetian Great Council (Maggior Consiglio), which allowed him to receive first-hand information regarding the news influencing the state’s foreign policy. In his diaries, he made detailed and relatively accurate entries that contain a wealth of information concerning the Kingdom of Hungary. His eight-volume diary covers the period between 1494 and 1512, an exceptionally active era for both countries.

In this study, I intend to present the diplomatic relations between the Kingdom of Hungary and Venice through the accounts of Priuli and the well-known Marin Sanudo from 1500–1503. In this context, I will address the financial subsidies provided by the Republic to Vladislaus II for the maintenance of troops, as well as how the Venetians evaluated these Hungarian military operations. To this end, I will utilize source fragments that have hitherto escaped the attention of historical scholarship.
