Petar II Petrović-Njegoš
Petar II Petrović-Njegoš was born Radivoje "Rade" Petrović on in the mountain village of Njeguši, near Cetinje. His father, Tomislav "Tomo" Petrović (b. 1762–63), was a member of the Petrović clan of the Njeguši tribe of Katuni "nahiya". Njegoš's mother, Ivana Proroković, hailed from the hamlet of Mali Zalaz and was the daughter of Njeguši captain Lazo Proroković. There is no reliable information about her exact year of birth, but it is believed that she was about ten years younger than her husband. Tomo and Ivana had five children; their eldest son was Petar ("Pero"), Rade was their middle son and Jovan ("Joko") was their youngest. The couple's daughters were named Marija and Stana; Marija was married to a Montenegrin chieftain named Andrija Perović, the "serdar" (count) of Cuce, while Stana was married to Filip Đurašković, the "serdar" of Rijeka Crnojevića.
Petar II Petrović-Njegoš
While staying in Italy, Njegoš was disturbed by reports of Omar Pasha's plans to invade Montenegro. He planned another visit to Saint Petersburg to enlist Russian support, but the czar refused to meet him. Njegoš headed back to Montenegro in the summer, having consulted physicians in Vienna on his way back. While in Vienna, he encountered Serbian photographer Anastas Jovanović, who persuaded him to pose for a picture in his studio. Jovanović's calotype portrait is the only known photograph of Njegoš in existence. Jovanović also photographed a group of "Perjanici" that had accompanied Njegoš on his journey to Italy, as well as the chieftains Mirko Petrović and Petar Vukotić. Njegoš returned to Cetinje in August 1851, with his health rapidly deteriorating. He died there on , surrounded by his closest associates and just two weeks shy of his thirty-eighth birthday. Eyewitnesses reported his last words as "love Montenegro and render justice to the poor."
