The Diário Oficial da União (literally Official Diary of the Union), abbreviated DOU, is the official journal of the federal government of Brazil. It is published since 1 October 1862 and was created via the imperial decree 1.177, of September 9 of the same year, as the Official Journal of the Empire of Brazil.^[1] Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Brazilian National Press.
