This article explores the legal writings of Brazilian sociologist and jurist Francisco José de Oliveira Vianna to reveal the global context that shaped Brazil's corporatist experiment in the 1930s. From the Labour Ministry, Oliveira Vianna was at the forefront of legal and political debates over how to create corporatist laws and institutions. He was often cast as an authoritarian and retrograde thinker, yet this article looks beyond those categories to examine how his engagement with the US New Deal inserted corporatism into global debates over the role of the state in economic recovery and social welfare.
