"In March 1871 the Commune took power in the abandoned city and held it for two months. Then Versailles seized the moment to attack and, in one horrifying week, executed roughly 20,000 Communards or suspected sympathizers, a number higher than those killed in the recent war or during Robespierre’s ‘Terror’ of 1793–94. More than 7,500 were jailed or deported to places like New Caledonia. Thousands of others fled to Belgium, England, Italy, Spain and the United States. In 1872, stringent laws were passed that ruled out all possibilities of organizing on the left. Not till 1880 was there a general amnesty for exiled and imprisoned Communards. Meantime, the Third Republic found itself strong enough to renew and reinforce Louis Napoleon’s imperialist expansion—in Indochina, Africa, and Oceania. Many of France’s leading intellectuals and artists had participated in the Commune (Courbet was its quasi-minister of culture, Rimbaud and Pissarro were active propagandists) or were sympathetic to it. The ferocious repression of 1871 and after was probably the key factor in alienating these milieux from the Third Republic and stirring their sympathy for its victims at home and abroad."
