  6. 1 January 1808 United States bans the importation of slaves 0 cit. A federal law took effect on 1 January 1808 prohibiting the import of enslaved people from abroad. Slavery itself continued and expanded, now fed by an internal trade rather than transatlantic shipments. politics / society ●●●●

  10. c. 1808 Prussia's Krümper system evades Napoleon's troop cap 0 cit. After Napoleon capped the Prussian army at 42,000 men following its 1806 defeat, reformers Scharnhorst and Gneisenau introduced the Krümper system, rapidly training conscripts and discharging them into a reserve to make room for new recruits. This let Prussia build up a much larger trained reserve than the treaty allowed, on paper without exceeding the limit. The reserve force helped Prussia field a substantially expanded army against Napoleon in 1813. politics / war ●●
  11. 1808 Prussian General Staff formally established 0 cit. Following defeat by Napoleon, Prussia formally established a permanent General Staff responsible for planning, training, and doctrine independent of any single commander, staffed by officers selected through the Kriegsakademie rather than by birth alone. This institutionalized professional military planning as a standing function of the state rather than something improvised for each war. The Prussian and later German General Staff became the model imitated by most modern armies. politics / war ●●●
  12. c. 1808 Prussia's Krümper System Evades Troop Caps 0 cit. After Napoleon's defeat of Prussia forced a treaty limiting the size of its standing army, Prussian reformers led by Gerhard von Scharnhorst introduced the Krümper system, rapidly training and discharging recruits so that a large reserve of trained men existed outside the capped standing force. The scheme let Prussia rebuild a mass fighting capacity while formally complying with the treaty's limits. It fed into the broader nineteenth-century Prussian model of conscription paired with a large trained reserve. politics / war ●●

After Parliament abolished the British slave trade in 1807, the Royal Navy formed the West Africa Squadron to intercept slave ships off the African coast.

Vidocq's model of using former criminals as detectives influenced the founding of detective bureaus across Europe and the United States. politics ●●
  28. c. 1812 Vidocq founds the forerunner of France's Sûreté 0 cit. Eugène François Vidocq, a former criminal turned police informant, was authorized to organize a plainclothes detective unit, the Brigade de Sûreté, staffed largely with ex-convicts who knew Paris's criminal underworld from the inside.

  29. c. 1812 Lautaro lodges and Spanish American independence 0 cit. Revolutionaries including Jose de San Martin were tied to the Lautaro lodges, secret societies modeled on Masonic forms and founded to work for Spanish American independence.

Following the 1813 union of the Antients and Moderns in London, the new United Grand Lodge of England reorganized its overseas Provincial Grand Lodges, including those in Bengal, Madras, and Bombay, under a single unified structure.

Colonial administrators, army officers, and merchants continued to dominate lodge membership across British India. politics / society
  33. 27 December 1813 Duke of Sussex leads the union of English Freemasonry 0 cit. Prince Augustus Frederick, Duke of Sussex, became the first Grand Master of the newly formed United Grand Lodge of England, created by merging the rival 'Antients' and 'Moderns' Grand Lodges. His brother, Edward, Duke of Kent, briefly served as Grand Master of the Antients to help broker the merger. Sussex went on to lead the united body for over three decades until his death in 1843. Some writers treat this royal stewardship of Freemasonry as evidence of hidden elite control; mainstream historians treat it as a well documented instance of aristocratic patronage rather than proof of a secret ruling hand. politics / society ●●●

  42. 1814 Prussia introduces universal military conscription 0 cit. Prussia enacted a law requiring military service from all able-bodied men regardless of class, backed by a reserve system, the Landwehr, that could rapidly expand the army in wartime. This broke with the older practice of relying on mercenaries or a narrow conscripted underclass while nobles served as officers by right of birth. The system became a template for conscription across continental Europe through the 19th and 20th centuries. politics / war ●●
  43. 24 August 1814 Militia rout at Bladensburg 0 cit. Hastily assembled American militia broke and fled before British regulars at the Battle of Bladensburg, opening the road to Washington, D.C., which the British burned days later. The defeat, mocked afterward as the Bladensburg Races, became a byword for the limits of poorly trained, poorly equipped militia against professional troops. It fed a long argument in American military policy over whether the militia system could be relied on for national defense. politics / war ●●
  44. 13 July 1814 Italy's Carabinieri founded 0 cit. King Victor Emmanuel I of Sardinia established the Carabinieri Royal Corps as a gendarmerie combining military and civil policing duties, modeled partly on the French gendarmerie.

  45. 13 July 1814 The Carabinieri founded in the Kingdom of Sardinia 0 cit. King Victor Emmanuel I created the Corps of Carabinieri as a mounted and foot force to guard the restored Savoyard state, modeled closely on the French gendarmerie.

  46. 26 October 1814 The Royal Netherlands Marechaussee established 0 cit. The newly independent Kingdom of the Netherlands created the Koninklijke Marechaussee, taking both the French gendarmerie model and its name from the old Maréchaussée left behind by French occupation.

Its survival shows how the gendarmerie template outlasted the Napoleonic empire that spread it. politics / society
  47. 1814 Malta and Gibraltar anchor the Mediterranean 0 cit. The Treaty of Paris in 1814 confirmed British possession of Malta, adding to Gibraltar, held since 1713.

  63. 1815 Nathan Rothschild and the Waterloo bond myth 0 cit. Nathan Mayer Rothschild made his London house a major force in British government finance around the Napoleonic Wars.

  65. 20 March 1815 The Congress of Vienna declares perpetual neutrality 0 cit. As Europe's powers redrew the map after Napoleon, they issued a declaration recognising the permanent neutrality of Switzerland and the inviolability of its territory. Neutrality here served the powers as much as the Swiss: a stable buffer state sat between France, Austria and the German lands where no rival could gain advantage. The principle was thus written into the postwar settlement by the great powers themselves. diplomacy / politics ●●●
  66. 20 November 1815 The Treaty of Paris guarantees Swiss neutrality 0 cit.

  67. 1815 Royal Navy supremacy after the Napoleonic Wars 0 cit. With the defeat of Napoleon in 1815, no rival fleet could match the Royal Navy. Britain emerged from the wars with the largest navy in the world and used it to police sea lanes, protect trade, and project power globally.

  68. 1815 The idea of Pax Britannica, 1815 to 1914 0 cit.

Local yeomanry cavalry charged into a crowd of roughly 60,000 gathered peacefully in Manchester to demand parliamentary reform, killing at least 18 people and injuring hundreds. The lack of a professional, disciplined police force capable of controlling crowds without cavalry became part of the case reformers made for a dedicated civil police. The massacre remains one of the most notorious instances of British authorities using military force against civilians. politics ●●
  79. 7 August 1819 Battle of Boyaca secures the north 0 cit. Bolivar's victory at Boyaca broke Spanish power in New Granada and made possible the republic of Gran Colombia.

  81. 25 February 1819 Dartmouth College defines the corporation as an artificial legal being 3 cit. In Trustees of Dartmouth College v. Woodward, the U.S. Supreme Court described the corporation as an artificial being existing only in contemplation of law.

It does not mean every human has a hidden corporate double. economy / politics ●●●●●

  89. 7 September 1822 Brazil's peaceful independence 0 cit. Rather than break away through war, Brazil becomes independent when Pedro, the heir to the Portuguese throne then resident in Brazil, declares it a separate empire and is crowned its emperor. The result is a relatively bloodless split and, unusually for the Americas, a monarchy that lasts until 1889. Slavery, however, continued for decades after independence. politics ●●
