The Dutch historiography of the middle of the 19thcentury was a culture of honour. Disputes over the reputations of historical figures were manifold. This article focuses on one controversy specifically that took place in the 1840s. The subject of debate was the 16th-century nobleman Henry of Brederode, his deeds, his character and his morals. The controversy was not only about content, however. Many suppositions about doing history and being a historian that otherwise remain tacit, were made explicit in the controversy (...) – especially concerning archive-based history. First, the participating historians themselves were judged – somewhat like Brederode himself – on the virtuousness, including the epistemic virtuousness, of their behaviour. Second, it was discussed whether archival documents were fit for use in historiography. To some, the use of these personal letters was ethically unjustifiable. Third, the location from which historical knowledge originated, mainly the archive, came under scrutiny. The singularity of the archive made historians relying on archival material prone to attacks on their trustworthiness. (shrink)
