The aim of this chapter is to provide a first impression of Leibniz’s long and deep engagement with history and historiography, in the hope of stimulating a more thorough investigation of this poorly studied aspect of his oeuvre. After a brief account of Leibniz’s work as an historian, the second section of the chapter explores Leibniz’s conception of history, which is shown to be profoundly embedded in his philosophical thought. The last section focuses on epistemological issues, namely, on Leibniz’s view of testimony as the epistemological ground of historical reconstruction, on the problem of historical credibility and scepticism, and on the role of sources in historiography.
