I want to know the answer to the following question:
When was the term Kievan Rus first coined?
All the background I'm provided with is that "In English, the term was introduced in the early 20th century, when it was found in the 1913 English translation of Vasily Klyuchevsky's A History of Russia, to distinguish the early polity from successor states, which were also named Rus.". Is that enough to answer the question?
Answer: no
