The term "the Low Countries" refers to the coastal regions of northwestern Europe, including the Netherlands, Belgium, and Luxembourg. Synonymous terms for this region include the Benelux countries, the Dutch-speaking countries, and the Lowlands. The latter term is derived from the fact that much of the region is characterized by low-lying land, as well as frequent flooding from nearby rivers and the sea. Other related terms include Flemish countries, referring specifically to the Flemish-speaking regions of Belgium, and the Rhine delta, which encompasses the westernmost regions of Germany as well as the Low Countries. Despite their small size, these countries have played important roles throughout European history, particularly in the development of trade and democracy.
