The Dutch Republic—officially known as the Republic of the Seven United Netherlands (Republiek der Zeven Verenigde Nederlanden), Republic of the United Netherlands, or Republic of the Seven United Provinces (Republiek der Zeven Verenigde Provinciën)—was a republic in Europe existing from 1581, when part of the Netherlands separated from Spanish rule, until 1795.
Until the 16th century, the Low Countries–roughly now corresponding to Netherlands, Belgium and Luxembourg–consisted of a number of duchies, counties and bishoprics, almost all of which were under the supremacy of the Holy Roman Empire, with the exception of the county of Flanders which was under the Kingdom of France.
Most of the Low Countries had come under the rule of the House of Burgundy and subsequently the House of Habsburg. In 1549 Holy Roman Emperor Charles V issued the Pragmatic Sanction, which further unified the Seventeen Provinces under his rule. Charles was succeeded by his son, King Philip II of Spain. In 1568 the Netherlands, led by William I of Orange, revolted against Philip II because of high taxes, persecution of Protestants by the government, and Philip’s efforts to modernize and centralize the devolved-medieval government structures of the provinces. This was the start of the Eighty Years’ War.
In 1579 a number of the northern provinces of the Low Countries signed the Union of Utrecht, in which they promised to support each other in their defence against the Spanish army. This was followed in 1581 by the Act of Abjuration, the declaration of independence of the provinces from Philip II.
In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.
The Republic of the United Provinces lasted until a series of republican revolutions in 1783-1795 created the Batavian Republic. During this period, republican forces took several major cities of the Netherlands. After initially fleeing, the monarchist forces came back with British, Austrian, and Prussian troops and retook the Netherlands. The republican forces fled to France, but then successfully re-invaded alongside the army of the French republic. After the French Republic became the French Empire under Napoleon, the Batavian Republic was be replaced by the Napoleonic Kingdom of Holland.
The Netherlands regained independence from France in 1813. In the Anglo-Dutch Treaty of 1814 the names “United Provinces of the Netherlands” and “United Netherlands” were used. In 1815 it was rejoined with the Austrian Netherlands, Luxembourg and Liège (the ‘Southern provinces’) to become the Kingdom of the Netherlands, informally known as the Kingdom of the United Netherlands, to create a strong buffer state north of France. After Belgium (1830) and Luxembourg (1890) became independent, the state became unequivocally known as the Kingdom of the Netherlands, as it remains today.
