The Frisians are an ethnic group indigenous to the coastal regions of the Netherlands and northwestern Germany. They inhabit an area known as Frisia and are concentrated in the Dutch provinces of Friesland and Groningen and, in Germany, East Frisia and North Frisia. The name is probably derived from frisselje. The Frisian languages are spoken by more than 500,000 people; West Frisian is officially recognised in the Netherlands, and North Frisian and Saterland Frisian are recognised as regional languages in Germany.

The cheval de frise was a defensive obstacle, existing in a number of forms, principally as a static anti-cavalry obstacle but also quickly movable to close breaches. The term was also applied to underwater constructions used to prevent the passage of ships or other vessels on rivers. In the anti-cavalry role the cheval de frise typically comprised a portable frame with many projecting spikes. Wire obstacles ultimately made this type of device obsolete.
The UNESCO World Heritage Site known as the Defence Line of Amsterdam is a 135-kilometre (84 mi) ring of fortifications around Amsterdam. It has 42 forts that are 10–15 kilometres (6.2–9.3 mi) from the centre and lowlands, which can easily be flooded in time of war. The flooding was designed to give a depth of about 30 centimetres (12 in), too little for boats to cross. Any buildings within 1 kilometre (0.62 mi) of the line had to be made of wood so that they could be burnt and the obstruction removed.
In Dutch history, the year 1672 is referred to as the Rampjaar. In May 1672, following the outbreak of the Franco-Dutch War and its peripheral conflict the Third Anglo-Dutch War, France, supported by Münster and Cologne, invaded and nearly overran the Dutch Republic. At the same time, it faced the threat of an English naval blockade in support of the French endeavor, though that attempt was abandoned following the Battle of Solebay. A Dutch saying coined that year describes the Dutch people as redeloos ("irrational"), its government as radeloos ("distraught"), and the country as reddeloos.
