came under worker control. In anarchist strongholds like Catalonia the figure was as high as 75%, but lower in areas with heavy Communist Party influence, which actively resisted attempts at collectivisation. Factories were run through worker committees, agrarian areas became collectivised and run as libertarian communes. Anarchist historian Sam Dolgoff estimated that about eight million people participated directly or indirectly in the Spanish Revolution. Mid-20th century Post-World War II The rise of Nazism and the start of World War II led to the dissolution of the LSI in 1940. After the War, the Socialist International was formed in Frankfurt in July 1951 as its successor. After World War II, social democratic governments introduced social reform and wealth redistribution via welfare and taxation. Social democratic parties dominated post-war politics in countries such as France, Italy, Czechoslovakia, Belgium and Norway. At one point, France claimed to be the world's most state-controlled capitalist country. It nationalised public utilities including Charbonnages de France (CDF), Électricité de France (EDF), Gaz de France (GDF), Air France, Banque de France and Régie Nationale des Usines Renault. In 1945, the British Labour Party led by Clement Attlee was elected based on a radical socialist programme. The Labour government nationalised industries including mines, gas, coal, electricity, rail, iron, steel and the Bank of England. British Petroleum was officially nationalised in 1951. Anthony Crosland said that in 1956 25% of British industry was nationalised and that public employees, including those in nationalised industries, constituted a similar proportion of the country's workers. The Labour Governments of 1964–1970 and 1974–1979 intervened further. It re-nationalised British Steel (1967) after the Conservatives had denationalised it and nationalised British Leyland (1976). The National Health Service provided taxpayer-funded health care to everyone, free at the point of service. Working-class housing was provided in council housing estates and university education became available via a school grant system. Nordic countries During most of the post-war era, Sweden was governed by the Swedish Social Democratic Party largely in cooperation with trade unions and industry. The party held power from 1936 to 1976, 1982 to 1991, 1994 to 2006 and 2014 to 2022, most often in minority governments. Party leader Tage Erlander led the government from 1946 to 1969, the longest uninterrupted parliamentary government. These governments substantially expanded the welfare state. Swedish Prime Minister Olof Palme identified as a "democratic socialist" and was described as a "revolutionary reformist". The Norwegian
