Until the middle of the 20th century, the history of Haiti was written by Haitian intellectuals, who had become historians through circumstance, in an effort to exalt the independence of the country and build a national identity. In the early 1950s, an intellectual revival favoured the emergence of professional historians that addressed new themes, including the Haitian history of international relations, based on methodical archival research. The 2010 earthquake significantly damaged the Haitian archives, particularly the diplomatic archives, that have not been accessible to researchers ever since. However, scholars have not stopped investigating the history and place of Haiti in the international system. This article summarises key moments in Haitian historiography of international relations. It also provides an overview of foreign diplomatic archives that, with the support of specialised libraries and research centres in Haiti and abroad, have become the primary sources of Haitian history.
