I want to know the answer to the following question:
In what year did Sviatoslav take over as leader?
All the background I'm provided with is that "Due to his abrupt death in an ambush in 972, Sviatoslav's 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 sons, which resulted in two of his three sons being killed.". Is that enough to answer the question?
Answer: no
