Structuralism appeared in academia for the first time in the nineteenth century and then reappeared in the second half of the twentieth century, when it grew to become one of the most popular approaches in academic fields concerned with the analysis of language, culture, and society. The work of Ferdinand de Saussure concerning linguistics is generally considered to be a starting point of twentieth century structuralism. The term "structuralism" itself appeared in the works of French anthropologist Claude Lévi-Strauss, and gave rise, in France, to the "structuralist movement," which spurred the work of thinkers in diverse fields such as the historian Michel Foucault, the political scientist Louis Althusser, the psychoanalyst Jacques Lacan, as well as the structural Marxism of Nicos Poulantzas.
