The Shanghai purge
12 Apr 1927 — Chiang turns on his communist allies: Green Gang enforcers and soldiers kill hundreds of unionists and militants in a morning, thousands in the weeks after, here and across the south. The First United Front dies in its victory. Remember the date — everything after 1927 follows from it.
THE MOMENT IN CONTEXT
On 12 April 1927, in Shanghai (the ◆ there — a site of memory in this atlas), Chiang turns on his allies: Green Gang enforcers and NRA soldiers kill hundreds of unionists and Communists in a morning, thousands across the south in the weeks after. The First United Front dies in its own victory. The Communist answer comes in August at Nanchang (the ✕), where Communist-led regiments seize the city for three days — the People’s Liberation Army still dates its founding to that morning — and fail; the survivors under Zhu De trickle into the hills, where Chapter 6 will find them. Hold that sequence: the purge drives the CCP out of the cities where it was born and into the countryside, where — after years of catastrophe — it will discover the strategy that wins this atlas. Nobody involved understood the favor being done.
From Chapter 5 — The Purge and the Nanjing Decade of China in Revolution, 1911–1949 (1929).

- The turn — Shanghai, 12 April 1927. Everything after 1927 follows from this morning: it fixed the civil war as the axis of Chinese politics for twenty-two years, expelled the CCP into…
- What it changed — The revolution goes rural. Driven from the cities, the Communist remnants converge on the mountainous borderlands where provincial authority runs out — Jinggangshan first,…
Then ask the room: Was the Nanjing decade a real modernization interrupted — or a façade that Japan merely exposed? The argued answer is on the chapter page →
