In 2022, Brazil completed 200 years of political independence in the midst of multiple and interconnected crises. Is there anything to celebrate? There is little room for rational optimism. We are currently faced with global health crises, climate emergencies, a decline in trust in science and democratic institutions, and a political and ideological attack against the state's role in social protection and the production of well-being. The dossier From Independence to Empire: Health and Disease in Nineteenth-century Brazil is an academic and political act of commemoration, that is to say, an act of remembering together, critically, the challenges, continuities, and changes in public health in Brazil as it transformed from its status as a colony of Portugal to a sovereign country in 1822.The history of healthcare in nineteenth-century Brazil provides some keys to better understanding public health in the twentieth century and its challenges in the twenty-first. It questions established views in Brazilian public health about the history and the "past" -often linear, unidirectional and evolutionary -and their search for "history lessons," especially in political and public health crises such as epidemics and pandemics.

The articles address the continuities and changes from the colonial experience in Portuguese America and the post-independence period through to the first decade of Republican Brazil.In 1922, the year of the first centenary of independenc...
