I want to know the answer to the following question:
What was severely lacking in Kievan in the 12th century?
All the background I'm provided with is that "In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'.". Is that enough to answer the question?
Answer: no
