History was front and center at the quadricentennial commemorations in 1954. This chapter explores the different constructions of São Paulo’s history that emerged during the IV Centenário, including the elaborate Historical Exposition in the newly inaugurated Ibirapuera Park, popular radio programs, and newspaper supplements. With few exceptions, these narratives minimized the role of people of African descent and northeastern migrants, while celebrating the contributions of European and Japanese immigrants. They also identified São Paulo not just as the most modern region of Brazil but as the epitome of modern Brazil.
