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.
Karađorđević dynasty
The Karađorđević (, Karađorđevići / Карађорђевићи, ) is a Serbian dynastic family, founded by Karađorđe Petrović, the "Veliki Vožd" ("Grand Leader") of Serbia in the early 1800s during the First Serbian Uprising. The relatively short-lived dynasty was supported by the Russian Empire and was opposed to the Austria-Hungary supported Obrenović dynasty. After Karađorđe's assassination in 1817, Miloš Obrenović founded the House of Obrenović. The two houses subsequently traded the throne for several generations. Following the assassination of Alexander in 1903, the Serbian Parliament chose Karađorđe's grandson, Peter I Karađorđević, then living in exile, for the throne of the Kingdom of Serbia. He was duly crowned as King Peter I, and shortly before the end of World War I, representatives of the three peoples proclaimed a Kingdom of the Serbs, Croats and Slovenes with Peter I as sovereign. In 1929, the Kingdom was renamed Yugoslavia, under Alexander I, the son of Peter I. In November 1945, the throne was lost when the League of Communists of Yugoslavia seized power, during the reign of Peter II.
