It has its origins, per the image leading the preview, in medieval guild systems. While this is a broad statement involving putting modern labels om historical insititions, there were explicit historical sources of inspiration for those who articulated modern corporatism, including in two Papal encyclicals, as a way to address labor relations and head off communism/left-wing solutions and create economic accord within a traditionalist/paternalist/Catholic framework.
Corporatism became an explicit ideological component of many fascist (or at least reactionary authoritarian) movements largely attributable to copying Mussolini: it heavily influenced the pre-Anschluss Austria government (“Austro-fascism”), Falangism in Spain, the Estado Novo in Portugal—and other countries where it was less centrally articulated but still an influencing concept under “Clerical-fascism” such as Nazi-controlled Slovakia which was led by a priest who was thrilled to lick Hitler’s boots.
Worth the read and worth looking into more beyond Wikipedia! It’s important to understand the ideological underpinning’s of ones enemies—especially when they’re (marginally) more intellectually articulated than “minorities bad.”
