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.
Peter I of Serbia
Following his father's death, Peter's financial situation deteriorated and he became dependent on his father-in-law, as well as Russia and his brother George, for support. Following the Royal Serbian Army's rout in the Serbo-Bulgarian War of 1885, Peter and Nicholas devised a plan to invade Serbia and overthrow the Obrenović dynasty. At the last minute, Nicholas abandoned the idea. Peter felt betrayed by the Prince's decision to back out, leading to long lasting animosity. Nevertheless, he remained in Cetinje until 1894, devoting himself to his surviving children, who finished their primary education there. In 1894, Peter moved to Geneva with his three children, where he was to remain until 1903. In 1899, Tsar Nicholas II invited Prince George and Prince Alexander, as well as Peter's nephew Paul, to attend the "Corps des Pages" military academy in Saint Petersburg free of charge. Due to his poor financial standing, which prevented him from sending the boys to private schools in Switzerland, Peter accepted the Tsar's offer.
