The Confidential Print series, issued by the British Government between c. 1820 and 1970, is a fundamental building block for political, social and economic research. The series originated out of a need to preserve the most important papers generated by the Foreign and Colonial Offices. These range from single-page letters or telegrams to comprehensive dispatches, investigative reports and texts of treaties. All items marked ‘Confidential Print’ were printed and circulated immediately to leading officials in the Foreign Office, to the Cabinet and to heads of British missions abroad. This collection consists of the Confidential Print for Central and South America and the French- and Spanish-speaking Caribbean. Topics covered include slavery and the slave trade, immigration, relations with indigenous peoples, wars and territorial disputes, the fall of the Brazilian monarchy, British business and financial interests, industrial development, the building of the Panama Canal, and the rise to power of rulers such as Perón in Argentina and Vargas in Brazil.
