Petar Kružić

Petar Kružić (16 October 1491 – 12 March 1537) was a Croatian knez, captain, soldier and defender of Klis, and the captain of Senj.

In the early 16th century Petar Kružić (knez of Klis) defended the Klis Fortress against Turkish invasion. He died in 1537 trying to break yet another siege by the Ottomans. After his death, the Klis defenders agreed to give the fortress to the Ottomans in exchange for their women, children and their own lives. In this way, the Ottomans finally conquered the Klis Fortress after almost two and a half decades of its successful defense.
