Karl Marx and Friedrich Engels, working in Brussels, had written "Manifesto of the Communist Party" (published in German in London on February 21, 1848) at the request of the Communist League (an organization consisting principally of German workers). Following the March insurrection in Berlin, they began agitating in Germany. They issued their "Demands of the Communist Party in Germany" from Paris in March; the pamphlet urged unification of Germany, universal suffrage, abolition of feudal duties, and similar middle-class goals. The middle and working classes thus shared a
Manifesto of the Sixteen goal. The manifesto was signed by some of the most eminent anarchists in Europe. The signatories originally numbered fifteen, with the mistaken sixteenth name, "Hussein Dey", being the name of the city in which Antoine Orfila lived. As the manifesto's co-authors, Jean Grave and Peter Kropotkin were among its first signatories. From France, the anarcho-syndicalists Christiaan Cornelissen and François Le Levé were signatories; Cornelissen was a supporter of the "union sacrée", a truce between the French government and trade unions during the First World War, and wrote several anti-German brochures, while the thirty-two-year-old Le Levé later joined the French Resistance
