Who were the Jin, and what impact did they have on the Song dynasty?

• A. The Jin were the Jurchen-ruled dynasty that conquered northern Song in 1127, forcing the Song to flee south
• B. The Jin were a Mongol allied state
• C. The Jin were a neighbor to the Song in the southwest
• D. The Jin were a separate Han Chinese faction within Song

Answer: (D)

The Jin were a Jurchen-led empire from Manchuria who rose to power in the early 1100s and established control over northern China. They conquered much of the northern Song realm, capturing the capital Kaifeng in 1127, which forced the Song to flee south and continue as the Southern Song. This upheaval ends the Northern Song and shifts the political center of gravity to the south, reshaping military focus, diplomacy, and state resources as the Song nation now defended its southern heartland while facing Jin power to the north. The Jin remained a major northern power for over a century, eventually falling to the Mongols, who then absorbed their territory. The Jin were not a Mongol ally, not a southwestern neighbor, and not a Han Chinese faction within the Song; they were a distinct non-Han empire from the north.
