1910s led a series of military offensives leading to the conquest and occupation of certain towns and districts in Baja California with the leadership of anarcho-communist Ricardo Flores Magón. Kropotkin's The Conquest of Bread, which Flores Magón considered a kind of anarchist bible, served as basis for the short-lived revolutionary communes in Baja California during the Magónista Revolt of 1911. To date, the best-known examples of an anarcho-communist society (i.e. established around the ideas as they exist today and achieving worldwide attention and knowledge in the historical canon), are the anarchist territories during the Spanish Revolution and the Makhnovshchina during the Russian Revolution. Through the efforts and influence of the Spanish anarchists during the Spanish Revolution within the Spanish Civil War starting in 1936, anarcho-communism existed in most of Aragon, parts of the Levante and Andalusia as well as in the stronghold of anarchist Catalonia before being crushed by the combined forces of the regime that won the war, Hitler, Mussolini, Spanish Communist Party repression (backed by the Soviet Union) as well as economic and armaments blockades from the capitalist countries and the Spanish Republic itself. Post-classical theoretical economic systems Participatory economics Participatory economics, often abbreviated parecon, is an economic system proposed by activist and political theorist Michael Albert and radical economist Robin Hahnel. For Albert, "participatory economics and participatory society provide a worthy, viable, and even necessary and potentially sufficient anarchist revolutionary vision". It uses participatory decision making as an economic mechanism to guide the production, consumption and allocation of resources in a given society. Proposed as an alternative to contemporary capitalist market economies and also an alternative to centrally planned socialism, it is described as "an anarchistic economic vision" and it could be considered a form of socialism as under parecon the means of production are owned by the workers. The underlying values that parecon seeks to implement are equity, solidarity, diversity, workers' self-management and efficiency (efficiency here means accomplishing goals without wasting valued assets). It proposes to attain these ends mainly through the following principles and institutions: Workers' and consumers' councils utilizing self-managerial methods for decision making Balanced job complexes Remuneration according to effort and sacrifice Participatory planning Albert and Hahnel stress that parecon is only meant to address an alternative economic theory and must be accompanied by equally important alternative visions in the fields of politics, culture and kinship.
