Petar Kružić (1490–1537)
Born 1490 CE, died 1537 CE.
Petar Kružić (cca. 1490 – 12 March 1537) was a Croatian captain and knez of Klis, captain of Senj, and knez of Lupoglav. In the early 16th century, Kružić defended the Fortress of Klis against Ottoman invasion. He died in 1537 trying to break yet another siege by the Ottomans. After his death, the Klis defenders moved to Senj, continuing to act as Uskoks. In this way, the Ottomans finally conquered the Klis Fortress after almost two and a half decades of its successful defense.
