John Hunyadi informs Francesco Sforza that he has read the letter given to him by the Duke's ambassador, Jacopo Del Bene, and informs him that he will send his reply to his secretary, Albert Vetési, whom he has authorized to negotiate and agree with him on his behalf.
The two letters are a valuable testament to the lively diplomatic relations between the Kingdom of Hungary and the cities of northern Italy in the early 1450s. In 1452–53, after the death of Cosimo de’ Medici, who ruled Florence and after the extinction of the Viscontis, Francesco Sforza who took control of Milan also sought the alliance of the Kingdom of Hungary against Venice and the Holy Roman Emperor Frederick III., Florence and Milan tried to win the support of the main dignitaries of the kingdom, such as the Ban of Slavonia, Frederick Cillei and his son Ulrik, and the governor John Hunyadi. Hunyadi, who had previously been to Italy with Sigismund of Luxembourg and spent two years at the court of the Duke of Milan, Filippo Maria Visconti, between 1431 and 1433, sent Albert Vetési, while Ulrik Cillei sent Friedrich Lamberger as ambassadors to Italy.
