Eighty Years' War in the context of "William the Silent"

The Westphalian system, also known as Westphalian sovereignty, is a principle in international law that each state has exclusive sovereignty over its territory. The principle developed in Europe after the Peace of Westphalia in 1648, based on the state theory of Jean Bodin and the natural law teachings of Hugo Grotius. It underlies the modern international system of sovereign states and is enshrined in the United Nations Charter, which states that "nothing ... shall authorize the United Nations to intervene in matters which are essentially within the domestic jurisdiction of any state."

According to the principle, every state, no matter how large or small, has an equal right to sovereignty. Political scientists have traced the concept to the eponymous peace treaties that ended the Thirty Years' War (1618–1648) and Eighty Years' War (1568–1648). The principle of non-interference was further developed in the 18th century. The Westphalian system reached its peak in the 19th and 20th centuries, but has faced recent challenges from advocates of humanitarian intervention.

The Republic of the Seven United Netherlands (Dutch: Republiek der Zeven Verenigde Nederlanden), also known as the United Provinces (of the Netherlands), and referred to in historiography as the Dutch Republic, was a confederation and great power that existed from 1588 until the Batavian Revolution in 1795. It was a predecessor state of the present-day Netherlands and the first independent Dutch nation state. The republic was established after seven Dutch provinces in the Spanish Netherlands revolted against Spanish rule, forming a mutual alliance against Spain in 1579 (the Union of Utrecht) and declaring their independence in 1581 (the Act of Abjuration), after which they confederated in 1588 (the Instruction of 12 April 1588) after the States General could not agree on a new monarch. The seven provinces it comprised were Groningen (present-day Groningen), Frisia (present-day Friesland), Overijssel (present-day Overijssel), Guelders (present-day Gelderland), Utrecht (present-day Utrecht), Holland (present-day North Holland and South Holland), and Zeeland (present-day Zeeland).

Although the state was small and had only around 1.5 million inhabitants, it controlled a worldwide network of seafaring trade routes. Through its trading companies, the Dutch East India Company (VOC) and the Dutch West India Company (GWC), it established a Dutch colonial empire. The income from this trade allowed the Dutch Republic to compete militarily against much larger countries. Major conflicts were fought in the Eighty Years' War against Spain (from the foundation of the Dutch Republic until 1648), the Dutch–Portuguese War (1598–1663), four Anglo-Dutch Wars (1652–1654, 1665–1667, 1672–1674, and 1780–1784), the Franco-Dutch War (1672–1678), War of the Grand Alliance (1688–1697), the War of the Spanish Succession (1702–1713), the War of Austrian Succession (1744–1748), and the War of the First Coalition (1792–1795) against the Kingdom of France.

The Thirty Years' War, fought primarily in Central Europe between 1618 and 1648, was one of the most destructive conflicts in human history. An estimated 4.5 to 8 million soldiers and civilians died from the effects of battle, famine, or disease, with parts of Germany reporting population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, the Torstenson War, the Dutch–Portuguese War, and the Portuguese Restoration War.

Its causes derived from religious conflict within the Holy Roman Empire, sparked by the 16th-century Reformation. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Catholic and Lutheran states, but was later destabilised by the expansion of Protestantism beyond these boundaries. Combined with disagreements over the limits of imperial authority, religion was thus an important factor in starting the war. However, its scope and extent was largely the consequence of external drivers such as the French–Habsburg rivalry and the Dutch Revolt.

The Dutch Golden Age (Dutch: Gouden Eeuw [ˈɣʌudən ˈeːu, ˈɣʌudə ˈʔeːu]) was a period in the history of the Netherlands which roughly lasted from 1588, when the Dutch Republic was established, to 1672, when the Rampjaar occurred. During this period, Dutch trade, scientific developments, art and overseas colonisation was among the most prominent in Europe. The first half of the period spanned from the beginning of the Eighty Years' War until its conclusion in 1648, with the second half lasting until the outbreak of the Franco-Dutch War. During the period, Dutch colonialists, many of them affiliated with the East India Company and West India Company, established trading posts and colonies in the Americas, Southern Africa and Asia, protected by the powerful Dutch States Navy. The Dutch also dominated the triangular trade and Atlantic slave trade during this period.

Dutch culture flourished during this period as well. However, by the end of the 17th century, conflicts with neighbouring powers as well as declining economic influence led to the end of this period. The process by which the Dutch Republic became one of the foremost maritime and economic powers of the world during the era has been referred to as the "Dutch Miracle" by historian K. W. Swart. The term "Dutch Golden Age" has been controversial in the 21st century due to the extensive Dutch involvement in slavery and colonialism during the period, and it has been deprecated by several museums in the Netherlands, including the Amsterdam Museum.

The Catalan Civil War, also called the Catalonian Civil War or the War against John II, was a civil war in the Principality of Catalonia, then part of the Crown of Aragon, between 1462 and 1472. The two factions, the royalists who supported John II of Aragon and the Catalan constitutionalists (Catalanists, pactists, and foralists), disputed the extent of royal rights in Catalonia. The French entered the war at times on the side on John II and at times with the Catalans. The Catalans, who at first rallied around John's son Charles of Viana, set up several pretenders in opposition to John during the course of the conflict. Barcelona remained their stronghold to the end: with its surrender the war came to a close. John, victorious, re-established the status quo ante bellum.

For the royalist side, the "rebels" were for having betrayed the fidelity they had sworn to their king; while the anti-royalists considered the royalists "traitors" for not being faithful to the laws of the "land", for being "enemies of public affairs" or simply for being "bad Catalans". Thus, the anti-royalist side developed a new conception of political society in which, according to Catalan historians Santiago Sobrequés [ca; es] and Jaume Sobrequés [ca], "solidarity among the men of a country was produced by having common laws and inhabiting the same land, not as, until then, by the fact of being vassals of the same sovereign». Thus, the modern concept of homeland had emerged that went beyond mere territorial ascription to take on a legal character, so the Catalan rebellion would be, as the French historian Joseph Calmette [fr; it] described, "the first of modern revolutions', hundred years before the Dutch Revolt.

Spanish Formosa (Spanish: Gobernación de Hermosa española) was a small colony of the Spanish Empire established in the northern tip of the island now known as Taiwan, then known to Europeans at the time as Formosa or to Spaniards as "Isla Hermosa" from 1626 to 1642. It was ceded to the Dutch Republic during the Eighty Years' War.

The Portuguese were the first Europeans to reach the island in 1544, and named it Formosa (Portuguese for "beautiful") due to the beautiful landscape as seen from the sea. The Spanish had translated the name into Spanish as "Hermosa" and is what was historically used in Spanish maps and documents about the colony.

The Spanish Netherlands (Spanish: Países Bajos Españoles; Dutch: Spaanse Nederlanden; French: Pays-Bas espagnols; German: Spanische Niederlande; historically in Spanish: Flandes, the name "Flanders" was used as a pars pro toto) were a collection of States of the Holy Roman Empire in the Low Countries, held in personal union by the Spanish Habsburgs, but not annexed to the Spanish Crown, thus encompassing the second period in history of the Habsburg Netherlands, that lasted from 1556 to 1714. This region comprised most of the modern states of Belgium and Luxembourg, as well as parts of northern France, the southern Netherlands, and western Germany, with the capital being Brussels. The Army of Flanders was given the task of defending the territory.

The Imperial fiefs in the former Burgundian Netherlands had been inherited by the House of Habsburg from the extinct House of Valois-Burgundy upon the death of Mary of Burgundy in 1482. The Seventeen Provinces formed the core of the Habsburg Netherlands, which passed to the Spanish Habsburgs upon the abdication of Emperor Charles V in 1556. Spanish hegemony in Netherlands was solidified following their victory in the Fall of Antwerp during the Eighty Years' War. When part of the Netherlands separated to form the autonomous Dutch Republic in 1581, the remainder of the area stayed under Spanish rule until the War of the Spanish Succession.

For most of its history, what is today Belgium was either a part of a larger territory, such as the medieval Carolingian Empire, or was divided into a number of smaller states. In the Middle Ages, the territory of present-day Belgium was fragmented into numerous feudal principalities, including the Duchy of Lower Lorraine, the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège, the County of Namur, the County of Hainaut and the County of Luxembourg. Belgium's modern shape can be traced back at least as far as the southern core of the medieval Burgundian Netherlands. The Eighty Years' War (1568–1648) later led to the split between a northern Dutch Republic and the Southern Netherlands from which Belgium and Luxembourg developed. The area, long a Habsburg stronghold, briefly came under Bourbon control during the War of the Spanish Succession. The resulting Peace of Utrecht transferred the area back to Habsburg control, creating what is now known as the Austrian Netherlands. The French Revolutionary wars led to Belgium becoming part of France in 1795. After the defeat of the French in 1814, the Congress of Vienna created two new states, the United Kingdom of the Netherlands and the Grand Duchy of Luxembourg, which were placed in dynastic union under the House of Orange-Nassau. The Southern Netherlands rebelled during the 1830 Belgian Revolution, establishing the modern Belgian state, officially recognized at the London Conference of 1830. The first King of Belgium, Leopold I, assumed the throne in 1831.

The first half of the twentieth century was tumultuous. Its historic neutrality was violated in each of the World Wars. During World War I, frustrated German invaders launched the Rape of Belgium. During the 1940 invasion, the quick surrender by Leopold III of Belgium to German forces drove a wedge between the King and his people. The King's attempt to return led to a constitutional crisis in 1950, which led to his abdication in favor of his son Baudouin. Belgium entered the second half of the twentieth century showing an unprecedented era of economic growth, as Belgium took an active role in the formation of the Benelux customs union with its neighbors. Ultimately, the Benelux union would serve as a model for the European Economic Community, a precursor to the European Union; to this day Brussels serves as the seat of many of the European Union institutions.
