Piotr Zborowski (died 13 September 1580) was a Polish voivode (Polish: wojewoda) of Sandomierz (since 1568), palatine, voivode and starosta of Kraków (since 1574), castellan (kasztelan) of Biecz (since 1565) and castellan of Wojnicz (since 1567).
He played an essential role in Polish–Lithuanian negotiations about elections of Henry of Valois and Stefan Bathory.
Specifically, he wanted to ensure that the ruler could handle government with a certain degree of authoritativeness.
Thus, he advocated for a prince or duke, far enough away that they could be driven from Poland by the nobility if they ever violated Polish laws,[1] such as the Henrician Articles, which was the de facto constitution of the Commonwealth.
[2] Thus, the candidates he supported, the Duke of Ferrara and Stephen Bathory, met Zborowski's criteria of being a minor noble, yet still having enough wealth and strength to rule the kingdom effectively.
