The Kievan Rus' state flourished until which century?

• A. 11th century
• B. 12th century
• C. 10th century
• D. 13th century

Answer: (B)

The Kievan Rus' achieved its greatest strength and cultural development during the 10th and early 11th centuries, but by the 12th century the realm had fractured into competing principalities and lost its unified power. That shift marks the end of its sustained flourishing as a centralized state. The later Mongol invasions in the 1230s–1240s further solidified the end of Kiev as the political center. So the period of sustained flourishing is best placed ending in the 12th century.
