How does The Communist Manifesto end?

The pamphlet closes Section IV by urging communists to labor openly, to support every revolutionary movement against the existing social order, and to prioritize proletarian international solidarity over narrow nationalism. The final sentences abandon polite debate for direct address: let ruling classes tremble at a communist revolution; proletarians have nothing to lose but their chains; workers of all countries should unite.

That ending matches the pamphlet’s tone — brief, declarative, meant for translation and broad circulation. There is no detailed post-revolution constitution here; strategy and rallying cry dominate. Classroom discussion can compare the close to Section III’s dissection of rival socialisms: after criticizing competitors, the Manifesto ends by naming its own side and audience unambiguously.
