  • France gained significant territorial concessions from Spain under the Treaties of Nijmegen, including the Franche-Comte and a string of fortified towns in the Spanish Netherlands.
  • The Dutch Republic recovered all territories occupied by France during the war, restoring its pre-war borders and confirming its continued independence and sovereignty.
  • The Popish Plot erupted in England as Titus Oates alleged a Catholic conspiracy to assassinate King Charles II and place the Catholic Duke of York on the throne, triggering mass hysteria.
  • The Popish Plot allegations led to widespread anti-Catholic persecution in England, with arrests, trials, and executions of innocent people accused of involvement in the supposed conspiracy.

  • The Scanian War between Sweden and Denmark continued despite the general European peace, with fighting along the Swedish-Danish border and in the Baltic.
  • The Popish Plot in England created a climate of fear and suspicion, with Catholic peers arrested and imprisoned in the Tower of London on the basis of fabricated evidence.
  • The murder of Sir Edmund Berry Godfrey, the magistrate who had received Titus Oates's deposition, fueled public belief in the Popish Plot and intensified anti-Catholic sentiment.

  • The Dutch economy began to recover from the effects of the war, with Amsterdam's financial markets and overseas trade networks regaining their full capacity.
  • War debts accumulated during the Franco-Dutch War burdened the treasuries of France, Spain, the Dutch Republic, and their allies, requiring fiscal adjustments and new taxation.

  • The fur trade in North America continued to be an important source of colonial revenue, with competition between French and English traders intensifying in the Great Lakes region.
  • Spanish colonial revenues from American silver mines continued to decline from earlier peaks, weakening Spain's ability to maintain its European military commitments.

Technology & Infrastructure

  • Christiaan Huygens developed an improved spiral balance spring for watches, enhancing the accuracy of portable timekeeping and contributing to the development of precision horology.
  • Vauban's fortification system along France's northeastern frontier was reinforced following the territorial gains of the Treaties of Nijmegen, creating a formidable defensive barrier.
  • Christopher Wren continued construction on St. Paul's Cathedral and the numerous parish churches rising across London as the post-fire rebuilding progressed.
  • The Royal Greenwich Observatory continued its observational program under Flamsteed, accumulating the precise stellar measurements needed for navigational improvements.
  • The Canal du Midi construction continued through its final phases, with the engineering achievement of connecting the Atlantic to the Mediterranean nearing completion.
  • Dutch engineering expertise continued to be applied to land reclamation, water management, and the maintenance of the extensive dike system protecting the Low Countries.
  • Advances in printing technology and the growing demand for books supported the expansion of publishing across European cities.
  • Military technology continued to evolve in the aftermath of the war, with armies incorporating lessons learned from six years of campaigning into training and equipment.
  • Shipbuilding techniques continued to advance, with the design of both warships and merchant vessels benefiting from the practical experience gained during the naval campaigns.
  • Road and bridge construction in France continued, with Colbert's infrastructure improvements facilitating the movement of goods and people across the kingdom.

Science & Discovery

  • Robert Hooke published a lecture proposing that the force of gravity decreases with the square of the distance, an idea he communicated to Newton and that would later contribute to Newton's theory of universal gravitation.
  • Antonie van Leeuwenhoek continued his microscopic observations, describing bacteria from dental plaque and other sources in letters to the Royal Society of London.
  • Christiaan Huygens published Traite de la Lumiere in draft form, presenting his wave theory of light, though the final publication would not appear until 1690.
  • Isaac Newton continued his private researches at Cambridge, working on problems of celestial mechanics and corresponding with other natural philosophers on questions of optics and gravity.
  • Giovanni Cassini continued observations at the Paris Observatory, refining measurements of the distances to planets and the orbital characteristics of Saturn's satellites.
  • Edmond Halley returned from St. Helena and published his catalog of 341 Southern Hemisphere stars, the first systematic survey of the southern sky using telescopic observations.
  • The Royal Society of London continued to serve as a center of scientific exchange, publishing the Philosophical Transactions and hosting demonstrations and discussions.

  • Thomas Burnett began work on his Sacred Theory of the Earth, which would attempt to reconcile geological observations with biblical accounts of creation and the flood.
  • European naturalists continued to expand their knowledge of the natural world through the collection and study of specimens from colonial territories.

Health & Medicine

  • The use of cinchona bark for treating malaria was increasingly accepted by European physicians, with the remedy becoming a standard part of the medical pharmacopoeia.
  • Apothecaries across Europe continued to serve as the primary providers of medical treatment, preparing and dispensing medicines based on herbal, chemical, and mineral ingredients.
  • The study of anatomy continued to advance through dissection at European universities, with new observations on the structure of organs and the circulatory system.
  • Maternal mortality remained high across all social classes, with complications of childbirth and puerperal fever claiming the lives of many women.
  • Public sanitation in European cities remained inadequate, with poor waste disposal and contaminated water supplies contributing to the prevalence of infectious diseases.

Climate & Environment

  • The Maunder Minimum persisted, with minimal sunspot activity contributing to the continued cooler temperatures and climate variability of the Little Ice Age.
  • The end of the Franco-Dutch War allowed the recovery of agricultural land that had been devastated by military campaigns, particularly in the Spanish Netherlands and the Rhineland.
  • The Little Ice Age continued to affect northern Europe, with cold winters and variable weather patterns challenging agricultural production and food security.
  • Atmospheric carbon dioxide concentration was approximately 275 parts per million, as later confirmed by ice core analysis.
  • Deforestation continued across Western Europe as post-war reconstruction and ongoing shipbuilding consumed timber resources at unsustainable rates.
  • The fur trade in North America continued to deplete beaver and other fur-bearing animal populations in eastern regions, driving trappers deeper into the continental interior.
  • Sugar plantations in the Caribbean continued to expand at the expense of tropical forests, with environmental degradation spreading across plantation islands.
