Which event marks the fall of the Southern Song?

• A. Jin capture of Kaifeng signaling the fall of the Southern Song
• B. Mongol conquest, culminating in 1279
• C. Civil war within Song
• D. Japanese invasion of the coast

Answer: (B)

The fall of the Southern Song is marked by the Mongol conquest culminating in 1279. After the Northern Song fell to the Jin in 1127 and the Song court fled south, the Southern Song continued from Hangzhou. The decisive end comes when Mongol forces complete their conquest, the last Song emperor surrenders, and the Yuan Dynasty is established. This makes the Mongol culmination in 1279 the definitive end of the Southern Song. The other events describe earlier or unrelated episodes: Jin capture of Kaifeng signaled the collapse of the Northern Song, not the Southern Song; civil war or Japanese invasions did not produce the final, dynasty-ending end of the Southern Song.
