Anarchist communism is a political philosophy and anarchist school of thought that advocates communism. It calls for the abolition of private property but retention of personal property and collectively-owned items, goods, and services. It supports social ownership of property and the distribution of resources "From each according to his ability, to each according to his needs".Anarchist communism was first formulated as such in the Italian section of the International Workingmen's Association. The theoretical work of Peter Kropotkin took importance later as it expanded and developed pro-organizationalist and insurrectionary anti-organizationalist sections. Examples of anarchist communist societies are the anarchist territories of the Makhnovshchina during the Russian Revolution, and those of the Spanish Revolution, most notably revolutionary Catalonia.
