The origin of social protection in France dates back to medieval times, with fraternal benefit societies. In the second half of the nineteenth century, systems of social assistance developed gradually, often launched by employers marked by social Catholicism, then relayed by the first laws. In 1930, modern social insurance was created, offering employees protection against certain risks: accidents, sickness, disability, maternity, old age, death ... During the Second World War, the National Council of Resistance designed the system of Social security, now at the heart of social protection. It was created just after the Liberation, by an order of 4 October 1945, followed by other texts. Gradually, protection has covered the entire population, while the benefits extend.
