Didn't the Paris Commune mark the first time that the proletariat stepped onto the political and historical stage?
No, the textile workers' uprising in Lyon, the Charter Movement and the workers' uprising in Sicily are all signs that the proletariat has stepped onto the historical stage. It was the first time that the proletariat participated in leading the revolution as an independent political identity. At that time, there was no sound guiding ideology, so they all failed. Marx, Engels and others founded Marxism through their own unique wisdom on the basis of summarizing their predecessors. The Paris Commune is an attempt by the proletariat to establish political power. This uprising has already had the guiding ideology-proudhon and Marxism (the former had a greater influence, and it was the former's wrong guidance that led to the ultimate failure of the revolution); Later, the October Revolution led by Marxism–Leninism finally won, which really opened a new era of socialist revolution.
