Johan de Witt (24 September 1625 – 20 August 1672) was a Dutch statesman and a major political figure in the Dutch Republic in the mid-17th century, when its flourishing sea trade in a period of globalization made the republic a leading European trading and seafaring power – now commonly referred to as the Dutch Golden Age. De Witt controlled the Dutch political system from around 1650 until shortly before his death in 1672, working with various factions from nearly all the major cities, especially his hometown, Dordrecht, and the hometown of his wife, Amsterdam.
