Netherlands, The

officially Kingdom of The Netherlands byname Holland

Country, northwestern Europe. Area: 16,034 sq mi (41,528 sq km). Population (2005 est.): 16,300,000. Capital: Amsterdam. Seat of government: The Hague. Most of the people are Dutch. Languages: Dutch (official), English. Religions: Christianity (Roman Catholic, Protestant); also Islam. Currency: euro. The Netherlands' southern and eastern region consists mostly of plains and a few high ridges; its western and northern region is lower and includes polders on the site of the Zuiderzee and the common delta of the Rhine, Meuse, and Schelde rivers. Coastal areas are almost completely below sea level and are protected by dunes and artificial dikes. Although densely populated, the country has a low birthrate. Its developed market economy is based largely on financial services, light and heavy industries, and trade. It is a constitutional monarchy with a parliament comprising two legislative houses; its chief of state is the monarch, and the head of government is the prime minister. Celtic and Germanic tribes inhabited the region at the time of the Roman conquest. Under the Romans trade and industry flourished, but by the mid-3rd century AD Roman power had waned, eroded by resurgent Germanic tribes and the encroachment of the sea. A Germanic invasion (406–407) ended Roman control. The Merovingian dynasty followed the Romans but was supplanted in the 7th century by the Carolingian dynasty, which converted the area to Christianity. After Charlemagne's death in 814, the area was increasingly the target of Viking attacks. It became part of the medieval kingdom of Lotharingia (see Lorraine), which avoided incorporation into the Holy Roman Empire by investing its bishops and abbots with secular powers, leading to the establishment of an Imperial Church. Beginning in the 12th century, much land was reclaimed from the sea as dike building occurred on a large scale; Flanders developed as a textiles centre. The dukes of Burgundy gained control in the late 14th century. By the early 16th century the Low Countries came to be ruled by the Spanish Habsburgs. The Dutch had taken the lead in fishing and shipbuilding, which laid the foundation for Holland's remarkable 17th-century prosperity. Culturally, this was the period of Jan van Eyck, Thomas à Kempis, and Desiderius Erasmus. Calvinism and Anabaptist doctrines attracted many followers. In 1581 the seven northern provinces, led by Calvinists, declared their independence from Spain, and in 1648, following the Thirty Years' War, Spain recognized Dutch independence. The 17th century was the golden age of Dutch civilization. Benedict de Spinoza and René Descartes enjoyed the intellectual freedom, and Rembrandt and Johannes Vermeer painted their masterpieces. The Dutch East India Co. secured Asian colonies, and the country's standard of living soared. In the 18th century Dutch maritime power declined; the region was conquered by the French during the French revolutionary wars and became the Kingdom of Holland under Napoleon (1806). The Netherlands remained neutral in World War I and declared neutrality in World War II but was occupied by Germany. After the war it lost the Netherlands Indies (Indonesia from 1949) and Netherlands New Guinea (in 1962; now Irian Jaya). It joined NATO in 1949 and was a founding member of the European Economic Community (later renamed the European Community and now embedded in the European Union). At the outset of the 21st century The Netherlands benefitted from a strong, highly regulated mixed economy but struggled with the social and economic challenges of immigration.
