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.
Prince-Bishopric of Montenegro
A long rivalry had existed between the Montenegrin metropolitans from the Petrović family and the Radonjić family, a leading clan which had long vied for power against the Petrović's authority. This rivalry culminated in Petar II's era, though he came out victorious from this challenge and strengthened his grip on power by expelling many members of the Radonjić family from Montenegro.
