Princess Zorka of Montenegro (Serbian Cyrillic: Кнегиња црногорска Зорка; 23 December [O.S. 11 December] 1864 – 16 March [O.S. 4 March] 1890) was the eldest child of the Montenegrin monarch Nicholas I and his wife Milena. Her name and title at birth was Ljubica Petrović-Njegoš, Princess of Montenegro. In 1883, she married prince Peter Karađorđević and she changed her name to Zorka (and her surname to Karađorđević). She died in childbirth while giving birth to Prince Andrija on 16 March 1890. Prince Andrija died shortly thereafter. Her husband Prince Peter went on to become King of Serbia in 1903, thirteen years after her death. Life Born in Cetinje, Montenegro at the time when her father was already the reigning Prince of Montenegro (his uncle Danilo II Petrović-Njegoš having died in 1860). She had eight younger sisters and three younger brothers. Zorka was educated in Russia before returning to Montenegro to be engaged to Petar Karađorđević. She spent her childhood up to the age of 11 in Cetinje, where she was educated by Cetinje teachers and a Swiss teacher Mrs. Nykom. In 1875, Princess Zorka was sent to Russia to continue her education at the Smolny Institute (attended by the girls from the most prominent Russian aristocratic families). After graduation, she returned to Cetinje. At the beginning of 1883, Prince Petar Karadjordjevic came to Cetinje. His intention was to marry in Cetinje, get closer to the Montenegrins and move there to live with his family. He asked for the hand of the young and beautiful Princess. The arrival of Petar Karadjordjevic in Cetinje and his engagement with Kneginja Zorka Petrovic-Njegos were disapproved by the opponents of these two dynasties, but the act was gladly accepted by the Serbian and Montenegrin people, who saw it as the confirmation of their future bond. The wedding of Princess Zorka (19 at the time) and Petar Karadjordjevic (39) took place at the Cetinje Monastery on 30 July 1883. The wedding party, like the engagement before it, was organized according to folk tradition, with many guests who could barely accommodate themselves in the small space of Cetinje. Zorka's sister Elena married the future King Victor Emmanuel III of Italy. Marriage and children Described as "exuberant" by one commentator, Zorka married Peter in Cetinje on 11 August 1883 in an Orthodox ceremony. They had five children: Princess Helen of Serbia (4 November 1884 – 16 October 1962).
