Anđeo Zvizdović (or Zvijezdović; c. 1420 – 7 June 1498) was a Franciscan friar and evangelist who negotiated the Ahdname of Milodraž – the promise of the freedom of religion to Bosnian people following the Ottoman conquest of Bosnia.
Zvizdović is said to have been born to a noble family in the village of Zvizde near Uskoplje (modern Gornji Vakuf), from which his surname is derived; according to other accounts, he was born in Vrhbosna (modern-day Sarajevo). His religious zeal was fueled by the sermons of Saint James of the Marches, who served as Vicar of Bosnia in the 1430s. James admitted him to the Franciscan Order and named him Anđeo (Angel); Zvizdović's original name is unknown. Zvizdović was particularly distinguished by his public speaking skills even as a novice monk, and was eventually elected head of the Franciscans of Bosnia proper.
After the Ottomans under Mehmed the Conqueror subjugated the Kingdom of Bosnia in 1463, and the subsequent execution of King Stephen, Zvizdović also functioned as the secular representative of the Bosnian people. He stepped forward to meet the Sultan and negotiated the Ahdname of Milodraž, the legal recognition of Bosnian Franciscans by the Ottoman Empire, as well as the promise of freedom of religion to Bosnia's Catholic population.
