The Manuel Dorrego national institute (full name: "Manuel Dorrego national institute of Argentine and Iberoamerican historical revisionism", ) was an institute of Argentina focused in the historiography of Manuel Dorrego. It was created on November 17, 2011, by decree 1880/2011. It is part of the Secretary of Culture of the national government. The first president was Pacho O'Donnell, working with other historians. The institute is named after Manuel Dorrego, an Argentine governor of the 19th century who was deposed and executed during the Argentine Civil Wars, but the scope includes as well other national heroes of Argentina, such as Juan Manuel de Rosas and Juan Perón, and Iberoamerican national heroes as Simón Bolívar and Bernardo O'Higgins. The decree considers that the historiography of Argentina is biased towards the Unitarian Party, as the first historians (such as Bartolomé Mitre), and seeks to counter such bias.
