    Franco-Dutch War: Louis XIV’s Ambition

    Louis XIV pushed France into the Dutch War with the intention of weakening the United Provinces of the Netherlands. After a concerted diplomatic effort to convert Sweden and England to the French cause a few years earlier, he began the attack in 1672. On March 28, 1672, England, an ally of France, was the first country to engage in the war. On April 6, France launched a counterattack against the United Provinces.

    The Dutch Stadtholder, William III of Orange, put up a strong fight against the French despite their effective progress in the early months.

    He managed to rally his troops and form an alliance against France, which included the Holy Roman Empire, Spain, Brandenburg, and Denmark. Attacked on three fronts, France ultimately forced the coalition to sign the Treaty of Nijmegen in 1678. France relinquished the United Provinces but secured its northern and eastern borders.

    Louis XIV initiated the Dutch War with the aim of weakening the United Provinces and countering the Triple Alliance (England, Sweden, and the United Provinces). The United Provinces, referring to the seven northern provinces of the Netherlands, had established themselves as a major naval and commercial power in Europe for several decades. Louis XIV was concerned that the United Provinces would thwart his expansionist goals by preventing him from acquiring the Spanish territories that made up the Spanish Netherlands.

    Before the conflict began, France unsuccessfully attempted to impose highly protectionist customs duties to reduce the commercial competition from the United Provinces. Seeing that this strategy had no effect, France chose to pursue an aggressive diplomatic campaign by forming alliances with England and Sweden.

    By doing so, Louis XIV isolated the United Provinces from their Triple Alliance allies. Ultimately, it was England that declared war on the United Provinces on March 28, 1672, followed by France on April 6, 1672.

    The war began due to Louis XIV’s territorial ambitions and his desire to annex portions of the Spanish Netherlands. He claimed that he had the right to these territories through his marriage to the Spanish Infanta Maria Theresa.

    Course of the Dutch War

    The Dutch War involved multiple fronts, including the North Sea, the Spanish Netherlands, Franche-Comté (a Spanish territory at the time), and Alsace. Some battles even took place in the Mediterranean, pitting the French admiral Duquesne against his Dutch counterpart, Ruyter. Less than three months after the war’s outbreak, the United Provinces, though outnumbered, dealt a blow to the Franco-English fleet at the Battle of Solebay on June 7, 1672, off the east coast of England. This naval battle resulted in significant losses on both sides, but the Franco-English blockade plans against Dutch ports failed.

    While the maritime invasion proved disastrous for the French, the land invasion promised a more favorable outcome. Conquests were made at Orsoy, Wesel, and Rheinberg. On June 12, 1672, the Rhine was crossed, and other towns were besieged, thanks in part to the efforts of the Duke of Luxembourg. The Prince-Bishop of Münster, an ally of Louis XIV, began the siege of Groningen on July 9, 1672. However, Dutch forces eventually halted the offensive after a month and a half of fighting. In June 1673, the French captured Maastricht, a particularly significant gain.

    A year later, Turenne, tasked with containing the Imperial forces, crossed the Rhine and achieved victories at Sinsheim and Ladenburg in June and July 1674, respectively. On the northern front, it was Condé who thwarted William of Orange’s troops on August 11, 1674, at the Battle of Seneffe. Fought on three fronts, namely Franche-Comté, the Spanish Netherlands, and Alsace, the war left its mark, compelling the coalition to seek peace.

    Commencing on March 28, 1672, the Dutch War concluded with the Treaty of Nijmegen on August 10, 1678, signed with the United Provinces. Nevertheless, the conflict continued with the other belligerents, each signing separate treaties with France (the Treaty of Nijmegen for the Holy Roman Empire, the Treaty of Fontainebleau for Denmark, and the Treaty of Saint-Germain-en-Laye for Brandenburg).

    Naval warfare played a crucial role in the Franco-Dutch War. King Charles II oversaw the British Royal Navy, which played a complicated role. Although nominally part of the Triple Alliance, Britain protected its own interests and sometimes cooperated with France. Notable naval conflicts included the Battle of Solebay in 1672, where English and French fleets clashed with the Dutch.

    From the perspective of states, the Dutch War pitted the Quadruple Alliance against France’s allies. The Quadruple Alliance united the United Provinces, the Archduchy of Austria, the Spanish Catholic Monarchy, and the Duchy of Lorraine. Their common enemy was the Kingdom of France under Louis XIV. To weaken the powerful United Provinces, France allied itself with England, Sweden, Bavaria, Liège, and the Principality of Münster.

    Leading figures in Europe were also involved in this war. King Louis XIV could count on the support of Charles II of England and Charles XI of Sweden. On the opposing side, the main leaders of the Quadruple Alliance included William III of Orange, the Stadtholder of the United Provinces, as well as Holy Roman Emperor Leopold I, Frederick William I of Brandenburg, Elector of Brandenburg and Duke of Prussia, and King Christian V of Denmark and Norway.

    William III of Orange, also known as William of Orange, was a prominent Dutch leader who played a crucial role in leading the Dutch Republic’s defense against French forces during the war. He later became King William III of England.

    Outcome of the Dutch War

    After years of war and despite several remarkable achievements, the Dutch suffered significantly from the conflict, with colossal human and commercial losses. However, in 1677, the marriage of Mary of York, niece of Charles II of England, to William of Orange marked a turning point by cementing an alliance between England and the United Provinces. Fearing the effects of this alliance, Louis XIV intensified his efforts and, at the beginning of 1678, ordered the capture of Ghent, Ypres, and Puycerda.

    During the negotiations in Nijmegen, the negotiators agreed on the main conditions of peace. Louis XIV insisted that Sweden, his devoted ally, reclaim the Swedish territories that Denmark and Brandenburg had taken during the war.

    However, the major winner was France, which saw its northern and eastern borders strengthened at the expense of Spain, which had to cede Franche-Comté. Even before that, England and the United Provinces had settled their differences in the Treaty of Westminster in 1674, resulting in a status quo ante bellum.

    Important Battles and Campaigns

    Battle of Solebay (1672)

    The Battle of Solebay was an important naval engagement that took place on May 28, 1672, during the Franco-Dutch War. It took place off the coast of Suffolk, England, near Solebay (now Sole Bay). The Duke of York (later King James II of England) and Admiral Comte de Tourville, leading the English and French fleets, respectively, engaged the fleet of the Dutch Republic under Admiral Michiel de Ruyter.

    Traditionally wary of the Dutch Republic’s dominance in trade and sea power, the English joined forces with the French to challenge Dutch naval supremacy. Ultimately, it ended inconclusively, with both sides claiming victory. However, the Dutch fleet managed to hold its position, preventing the British and French from achieving their objectives, which included the planned invasion of the Dutch Republic.

    Siege of Utrecht (1673)

    The Siege of Utrecht was a land battle that took place between June 13 and July 30, 1673, during the Franco-Dutch War. The city of Utrecht, in the heart of the Dutch Republic, was a strategic target for French and English forces. The siege marked a critical stage in the conflict, demonstrating the resilience of the Dutch defenses.

    With assistance from British forces, Louis II de Bourbon, Prince of Condé, led the French army as it besieged Utrecht. The Dutch, led by William III of Orange, mounted a determined defense using innovative fortifications and a network of water defenses. The protracted siege and the tenacity of the Dutch led to a stalemate and eventually the siege was lifted. The failure to capture Utrecht was a significant setback for the Franco-British alliance.

    Naval Battles in the Mediterranean

    In addition to major conflicts in the North Sea and the English Channel, the Franco-Dutch War also saw several naval battles in the Mediterranean. These conflicts occurred as part of the wider struggle between France and the Dutch Republic and had far-reaching consequences for trade and colonial interests. The Mediterranean theater was the scene of battles between the French and Dutch fleets, and at times other Mediterranean powers joined in.

    Treaty of Westminster (1674)

    The Treaty of Westminster was signed on February 19, 1674, and determined the outcome of the Franco-Dutch War. The treaty was negotiated between England and the Dutch Republic. The treaty effectively ended England’s participation in the war after it withdrew from its alliance with France.

    The terms of the treaty included provisions on mutual defense, trade agreements, and territorial arrangements. Key agreements included the return of British colonial conquests, such as New Netherland to Dutch control. This treaty significantly changed the balance of power in Europe and paved the way for a more favorable period in Dutch-British relations.

    The Treaty of Westminster had lasting effects not only in the context of the Franco-Dutch War but also in the context of European politics and colonial possessions in the late 17th century. It reshaped alliances and rivalries in the region and contributed to the relative decline of French influence.

    Consequences of the Dutch War

    The Dutch War and the Treaty of Nijmegen somewhat altered the landscape of Europe. France emerged as the major winner, with smoother northern borders. With fewer enclaves due to gains in various strongholds such as Ypres, Saint-Omer, Cambrai, and Valenciennes, France became easier to defend and administer. However, this came at the expense of returning several enclaves, like Maastricht and the Principality of Orange, to William III, as well as Charleroi and Courtrai to Spain.

    Louis XIV also acquired Franche-Comté from Spain. Regarding Lorraine, it was returned to its duke by Emperor Leopold I of Habsburg under the Treaty of February 5, 1679. However, as the duke refused to comply with the treaty, Lorraine remained occupied by France.

    The Treaty of Nijmegen was a humiliation for Spain. It was the major loser in the territorial division. Despite some concessions in the Spanish Netherlands by France, such as Charleroi, Binche, and Courtrai, Spain had to part with Franche-Comté and several strongholds like Cambrai, Saint-Omer, Ypres, or Valenciennes. The military defeat also had diplomatic repercussions for Spain.

    Following the Glorious Revolution of 1688 in England, William of Orange, husband of Mary Stuart, daughter of James II, ascended to the English throne alongside Mary. The Glorious Revolution was partly motivated by the fears of the English elite regarding the possible restoration of Catholicism in England under James II’s reign. William of Orange, as a Protestant and Stadtholder of the United Provinces, was seen as a leader capable of ensuring the preservation of Protestant liberties in England.

  • Jan Luyken: 17th-Century Dutch Poet and History Painter

    Jan Luyken: 17th-Century Dutch Poet and History Painter

    Jan Luyken (or Johannes Luiken; April 16, 1649–April 5, 1712) was a Dutch poet, illustrator, history painter, and engraver, active during the time period known as the United Provinces of the Netherlands. Jan Luyken made engravings for many popular books and works, including the engraving of a peat boat the Dutch used to fool the Spanish into giving up Breda in 1590.

    His German immigrant father, Caspar Luyken the Elder, was a Mennonite (Anabaptist) school teacher. Jan was a passionate young guy who took painter Martin Zaagmolen’s classes. Even though Zaagmolen wasn’t a talented painter, he was a well-respected educator. Jan had an open admiration for attractive ladies.

    At 26 years old, Jan Luyken had a profound religious experience that moved him to write moralistic poetry. Married to Maria de Oudens from the city of The Hague in 1672, Jan named his first son Caspar Luyken (1672–1708), whom he trained in engraving.

    They specialized in producing devotional works depicting religious and historical topics. Between 1669 and 1712, Jan Luyken was engaged in Amsterdam, and between 1699 and 1705, he was also in the city of Haarlem.

    His Engravings

    The majority of Luyken’s output was devoted to book illustration. Outside of Amsterdam, Luyken has worked for a wide variety of publishing firms. Many museums in the Netherlands now claim to have his engravings on display, which are believed to be 3,000 in total.

    Famously, he contributed 104 copper etchings to the 1685 edition of the Martyrs Mirror, written by Thieleman J. van Braght. The Martyrs Mirror Exhibit by the Kauffman Museum showcased 31 of these plaques that are still in existence.

    In 1694, Jan and his son Caspar released “The Book of Trades“, which is filled with engravings depicting various 17th-century commercial activities. And they were the brains behind a slew of engravings on topics like The Religious Persecution, The Plagues of Egypt, and The Last Judgment.

    His Literary Life

    In addition to engraving, Jan Luyken had a highly productive literary life. In 1671, he released Duitse Lier, his first novel. This book also contains poems he wrote about his affair with Maria de Oudens.

    After some time, Jan decided to become a part of the Mennonite group based in Beverwijk. His interest in Christian mysticism led him to associate with the Gichtelianer, whose goal was spiritual union with Jesus in the form of the heavenly Sophia (Gnosticism).

    They became a group of critics of the church who had been banished from Regensburg in 1665 and had since settled in Amsterdam.

    In 1678, Jan Luyken released a collection of verses he had written that explored mysticism and pantheism. The Doopsgezinde Bundel, the hymnal of the Dutch Mennonite Church, has several of his poems. Jan provided the original figurative images for each of these publications.

    There were five children born to Jan Luyken and Maria de Oudens, but four of them passed away at a young age. Caspar, the firstborn, was the only child to make it. There are 36 documented collaborations between him and his father.

    Cross allusions

    Engravings of The Religious Persecutions by Jan Luyken adorn the walls of the home of Joris-Karl Huysmans’ antihero Jean Des Esseintes in the 1884 novel À Rebours (‘Against Nature’).

    What he calls “appalling engravings containing all the tortures that the madness of religion could conceive” is an apt remark by Jean Des Esseintes about the engravings.

    His visual renderings and his ability to rebuild past eras and locations fascinate Des Esseintes.

    Acknowledgment

    Jan Luijkenstraat (‘Jan Luyken Street’) is the name of one of the streets in Amsterdam’s historic district that honors prominent painters from the city’s Golden Age (‘Dutch Golden Age’). The Rijksmuseum, one of the first buildings on the street, is the museum where you can find the greatest concentration of Luyken’s works.

    In the first half of the 19th century, Pietists (of Lutheranism) received his devotional lyrics very favorably. The “reformers” of the early 20th century also showed an affinity for Luykenian works.

    Some of Jan’s illustrated books were published in the 20th century, while others were reissued three to seven times before the 18th century. Chinese porcelain featuring his religious themes was widely distributed throughout Europe in the middle of the 18th century.

    A traveling exhibition called “Martyrs Mirror” has been showing the 30 surviving copper plates of Jan Luyken since 1990 around North America, where there is a sizable Anabaptist population. The exhibition has visited more than 20 US states and five Canadian provinces.

  • The First Submarine Was Invented by Cornelis Drebbel

    The First Submarine Was Invented by Cornelis Drebbel

    The Dutch inventor and engineer Cornelis Jacobszoon Drebbel, who designed and built the first submarine, is pretty much unheard of today by many people. But because of how brilliant he was and how well he understood how nature and chemistry worked, he is rightly thought of as one of the most successful and well-known inventors of the 17th century. Drebbel created and constructed the first submarine in 1620, making it one of his most important innovations. Drebbel’s wooden submarine, driven by oars, was built to stay submerged for hours. It was one of the first submarines that could actually be used, and it led the way for more sophisticated submarines to be built in the years to come. Drebbel’s work on submarines paved the way for undersea exploration.

    How did the Drebbel submarine work?

    The crew members untied the bladders and sucked out all the water before rowing to the surface. The submarine was therefore able to safely descend to depths of around 13 to 16 feet (4-5 meters) for several hours. A rudder allowed for control, while four oars propelled the boat forward by being fed into the water via leather seals.

    Why did Cornelis Drebbel invent the submarine?

    Initially, Cornelis Drebbel created his submarine to help humans learn more about the marine environment, but he quickly realized its potential as a military weapon as well. However, it took another 150 years for them to see action in naval conflicts.

    How did Drebbel’s Perpetuum Mobile work?

    It worked by reacting to changes in the pressure and temperature of a contained liquid or gas. These variations provided the power required to get the gears going as long as possible. Without an external force, it wouldn’t be considered perpetual motion.

    The English king commissioned Cornelis Drebbel

    Drebbel was invited to King James I of Scotland and England’s court in 1604. At the period, academics were more often asked to present their knowledge and abilities. Theologians and alchemists were welcomed in addition to scientists. But, the invitations were still rarely from abroad. The overseas journey had some benefits since the English monarch was inspired enough by Drebbel’s efforts to collaborate with him.

    In that year Drebbel was summoned to England to show his impressive “Perpetuum Mobile” device to King James I (1566–1625). As the news about this fascinating perpetual motion clock spread, Drebbel gained a huge reputation and began to receive invitations from other European countries to showcase his device.

    Between 1620 and 1624, Drebbel built the first functional submarine on a commission from the English king. Drebbel built three effective submarines in total during the period.

    How Drebbel invented the world’s first submarine

    drebbel replica first submarine
    Drebbel’s most advanced submarine is on display at Heron Square in the Richmond-upon-Thames neighborhood of London.

    Drebbel’s greatest achievement was that he designed and made an invention that he owes his reputation to today: The world’s first submarine. Unfortunately, there is no original drawing of Drebbel’s invention to date. Nevertheless, there are close estimates and calculations of how the submarine could be built with a contemporary eye. Between 1620 and 1624, while working for the British Royal Navy, Drebbel made three different forms of submarines. He tested all three in London, on the River Thames. According to witnesses, the latest submarine was able to remain submerged for 3 hours at 13 to 16 feet below the surface.

    In front of King James I and a large crowd of Londoners, he showed off his third submarine. The submarine made a round trip from Westminster to Greenwich. It was the first true submarine in history.

    Drebbel’s wooden submarine was best characterized as a wooden round canoe-style rowing boat. The stern seemed to be the fin of a giant fish, and the oars protruded directly through the hull. It was a lovely figure, smiling and amazed. On the Thames River, the boat did its maiden dive. While rowers ensured that the boat was pushed, it is still not officially known how the crew was given air.

    Cornelis Drebbel tried to persuade the British Royal Navy to use his submarine in naval combat. Despite his relationship with the royal family, the Navy was not interested in this proposal. For submarines to be used for military purposes, 150 years had to pass.

    How did Drebbel’s submarine work?

    Very large pouches made from pigskin used in these submarines were filled or emptied with water, this would allow the boat to go down or up in the water. The wooden double-hull submarine had holes sealed with waterproof leather, in which oars were placed.

    The third and largest boat or submarine developed by Cornelis Drebbel could accommodate 16 people, including 12 rowers. The hull was covered with oiled leather to provide waterproofing. Some records suggest that there were long pipes on the boat that could reach all the way to the surface to provide air for the rowers. There is also evidence that Drebbel created a chemical reaction by heating potassium nitrate which produced oxygen for rowers.

    Oxygen produced by burning

    According to the legend, the crew spent nearly three hours underwater. Drebbel must have thus considered adding fresh oxygen to the waterproof vessel. There are a few hypotheses for this, but the most plausible one is that when saltpeter, or nitrate, is heated, oxygen is released. Drebbel was an expert alchemist long before he worked on the first submarine, so the notion isn’t outlandish in and of itself. The details are still speculative since nothing was really written about his invention and rumors about it were passed around orally. As a result, the legends surrounding this submarine are still unclear.

    Cornelis’ career was eventually furthered by chemistry; he later worked on explosives for the Royal Navy. In summary, Drebbel had come a great way and would remain in England for a considerable amount of time before passing away in London on November 7, 1633. In a number of Dutch towns, including Amsterdam, Delft, Alkmaar, and The Hague, he has streets named after him. Cornelis Drebbel has a minor lunar crater named in his honor as well. Cornelis Drebbelweg, a street in Delft, the Netherlands, is named in his honor.

    Who was Cornelis Drebbel?

    Cornelis Drebbel is best known for the invention of the very first submarine.
    Cornelis Drebbel is best known for the invention of the very first submarine.

    The map artist, painter, engraver, and lens maker, Cornelis Drebbel was born as the son of a wealthy farmer in Alkmaar, The Netherlands. However, he received very little formal education. Although he picked up the basics of the Latin language in his later years, he probably only received a primary education and did not go to university. Drebbel was skilled at conducting numerous experiments despite lacking a formal education.

    At the age of 20, Drebbel began working as an apprentice in the Harlem workshop of Dutch painter, engraver, and publisher Hendrick Goltzius (1555–1617). During his apprenticeship where he also lived in Goltzius’ home, Drebbel had the chance to learn much more than engraving. He learned the subtleties of alchemy, and throughout his life, his work was determined by four elements: Earth, air, water, and fire.

    Drebbel returned to Alkmaar in 1598 and began to work on some versatile inventions. In 1604, he exhibited the first invention that would bring him fame. This was a dazzling astronomical clock machine called Perpetuum Mobile. In his patent application, Drebbel stated that the device could work for years without a visible power source.

    Perpetuum Mobile was an astronomical almanac showing the time, day, date, phases of the Moon, the positions of the Sun, and the positions of the planets. This interesting device was powered by changes in air pressure and temperature. Cornelis Drebbel, of course, was aware of the delicacy of this phenomenon but was delighted with the mystical atmosphere created around his Perpetuum Mobile.

    On the emperor’s request, Drebbel visited the Prague court of Rudolf II in 1610. Rudolf appointed him Chief Alchemist after seeing his amazing perpetual motion device; Drebbel really just claimed that it could rewind continuously due to variations in air pressure. It contained a sealed glass tub where liquid would expand and contract, allowing the clock to perpetually spin backward.

    Cornelis Drebbel’s other inventions

    Cornelis Drebbel also experimented with light and lenses. In 1630, Drebbel developed the first version of the “projector,” an early form of magic lantern or slide projector, and also one of the first microscopes. Both devices used special lenses, which were produced by a machine of his design. Drebbel’s microscope had visibly improved features compared to its predecessors and was an important advance in the field of microscopy.

    From 1604 until his death, Drebbel exhibited many new or improved inventions. Among them was a process for making red paint. This technology was used for many years after Drebbel’s death. Drebbel also made a boiler with a thermostat. It was a thermostatic mobile furnace for the Dutch army; a kind of ventilation system that is exhibited today at Westminster Hall in London; and also, an automatic incubator. This thermostatic furnace is the first known self-controlled device or instrumental control system in history.

    Drebbel invented a rather primitive but still very significant thermometer. But this thermometer device wasn’t put together based on the idea that the compressed air in the glass tube would expand and contract. Instead, Drebbel’s invention was some kind of a thermoscope. The thermoscope was a device that gave insight into temperature without a scale to aid measurement. At about the same time, at least three experimenters were working on an air thermoscope. But what distinguishes Drebbel from them was that his device could be used to control thermostatic devices. Drebbel’s furnace had a major influence on later scientists.

    The use of precision thermometers in the 18th and 19th centuries helped scientists better understand the behavior of substances and contributed to the development of the concept of energy.
