The Role of ‘Rerum Per Octennium’ in Understanding Dutch-Brazilian History

The Barlaeus Rerum Per Octennium is a seminal work that has played a crucial role in shaping our understanding of Dutch-Brazilian history. Written by Caspar Barlaeus in 1647, this Latin text, whose full title translates to “History of the Recent Events in Brazil,” provides a comprehensive account of the Dutch occupation of northeastern Brazil from 1636 to 1644. As a primary source document, it offers invaluable insights into the colonial ambitions, administrative challenges, and cultural encounters that characterized this unique period in South American history.
