Question: What nationality is Yaropolk I Of Kiev's father?

Knowledge 1: Yaropolk I of Kiev
Yaropolk I Sviatoslavich (952 – 11 June 978)(Old East Slavic: Ꙗрополкъ, sometimes transliterated as "Iaropolk") was a young and rather enigmatic ruler of Kiev between 972 and 980.He was the oldest son of Svyatoslav.His royal title is traditionally translated as "Prince". [SEP] Knowledge 2: Sviatoslav I of Kiev
Sviatoslav I Igorevich (Old East Slavic: С~тославъ / Свѧтославъ Игорєвичь, "Sventoslavŭ / Svantoslavŭ Igorevičǐ"; 943 – 26 March 972), also spelled Svyatoslav was a Grand Prince of Kiev famous for his persistent campaigns in the east and south, which precipitated the collapse of two great powers of Eastern Europe, Khazaria and the First Bulgarian Empire.He also conquered numerous East Slavic tribes, defeated the Alans and attacked the Volga Bulgars, and at times was allied with the Pechenegs and Magyars.His decade-long reign over the Kievan Rus' was marked by rapid expansion into the Volga River valley, the Pontic steppe, and the Balkans.By the end of his short life, Sviatoslav carved out for himself the largest state in Europe, eventually moving his capital in 969 from Kiev (modern-day Ukraine) to Pereyaslavets (identified as the modern village of Nufăru, Romania) on the Danube.In contrast with his mother's conversion to Christianity, Sviatoslav remained a staunch pagan all of his life.Due to his abrupt death in ambush, his conquests, for the most part, were not consolidated into a functioning empire, while his failure to establish a stable succession led to a fratricidal feud among his three sons, resulting in two of them being killed.
