In the Habsburg Netherlands (1482–1794) and the Dutch Republic (1581–1795) laws were often known as "Placards" (Dutch: plakkaat) after their form of publication by way of a placard that was nailed to a wall in a public place. An important example is the Dutch declaration of independence of 1581, known in Dutch as Plakkaat van Verlatinghe.
