July 21, 1774

Treaty of Küçük Kaynarca

The treaty made the Crimean Tatars politically independent while leaving the Ottoman sultan a religious role as caliph — a deliberately split sovereignty.

21 July 1774 at Küçük Kaynarca

At Küçük Kaynarca in Dobruja on 21 July 1774, Russian and Ottoman representatives concluded a peace treaty ending the six-year Russo-Ottoman War of 1768–1774. Article I declared an end to hostilities, a general amnesty and perpetual peace between the two empires.

Pyotr Rumyantsev, the field marshal who had commanded the victorious Russian army, represented Russia. Ahmed Resmî Efendi led the Ottoman delegation with İbrahim Münib Efendi, and the grand vizier Muhsinzade Mehmed Pasha was a formal signatory; the delegation reportedly arrived 200 strong.

Fortresses, an indemnity, and independent Tatars

Article III declared the Crimean, Budjak, Kuban and associated Tatar peoples politically independent of both empires while preserving the Ottoman sultan's religious role as caliph. It did not cede Crimea to Russia.

Russia obtained Azov, Kerch, Yenikale, Kinburn and claims involving Kabardia, and returned Wallachia, Moldavia and other occupied Ottoman territories under specified guarantees. The indemnity was 4.5 million rubles — 15,000 purses, payable in three instalments.

The treaty also opened Ottoman waters and ports to Russian merchant shipping and authorized Russian consulates in Ottoman territory.

The clause everyone quotes

Articles VII and XIV required the Porte to protect Christianity and permitted a Russian-associated church in Constantinople, with Russian representations tied specifically to that church. They did not unambiguously grant Russia a general protectorate over every Ottoman Orthodox Christian.

The meaning is genuinely disputed because the Russian, Ottoman Turkish and Italian versions differ. Influential textual studies find that the treaty protected only the proposed Constantinople church through Russian representations, assigning general protection of Christianity to the Porte.

That church apparently was never built, and its description varies among the treaty-language versions.

What the sources leave uncertain

  • The treaty is conventionally dated 10 July 1774 Old Style, equivalent to 21 July Gregorian. A modern Turkish encyclopedia entry prints 26 July, but the treaty scan and Davison's scholarly study support the conventional 10/21 July dating.
  • The meaning of Articles VII and XIV is genuinely disputed because Russian, Ottoman Turkish and Italian versions differ.

10 January 1776, from Robert Bell's shop

On 10 January 1776 the Philadelphia printer and bookseller Robert Bell issued Thomas Paine's Common Sense without Paine's name. The title page identified the author only as "an Englishman."

The Pennsylvania Evening Post had advertised the pamphlet on 9 January. The University of Michigan's Clements Library dates publication to 10 January, while some catalogues treat the advertisement as the issue date.

Four subjects, seventy-nine pages

The pamphlet directly urged the colonies to declare independence and sever their connection to the British monarchy. Its title page organized the case under four subjects: government and the English constitution; monarchy and hereditary succession; the present American crisis; and America's ability to proceed independently.

Bell printed it at his Third Street shop in simple paper wrappers, catalogued as [4], 79, [1] pages — not the 47 often repeated. Benjamin Rush recalled encouraging Paine to write and giving the work its title.

Sold out, then a quarrel with the printer

The first printing of 1,000 copies sold within roughly two weeks.

Bell proceeded with another edition despite Paine's request to wait for revisions, prompting Paine to move his enlarged text to William and Thomas Bradford. Bell claimed the first printing had produced no profit; Paine disputed the accounting.

Paine was not writing into a vacuum. John Adams later stressed that the arguments for independence had already been repeatedly urged in Congress.

8 March 1776, at Bloomfield Colliery

In 1776 a full-size engine incorporating James Watt's separate condenser was set to work at Bloomfield Colliery near Tipton and Dudley — the first Boulton-and-Watt engine to operate commercially outside the Soho Manufactory.

The date comes from Aris's Birmingham Gazette of 11 March, which reported that the engine had started "Friday last", and is confirmed by specialist local histories.

The colliery's proprietors had abandoned a partly erected conventional engine to back Watt's unproven full-size design.

A fifty-inch cylinder at fifteen strokes a minute

John Wilkinson supplied the large iron foundry components, the specialized condenser, valve and piston work came from Soho, and Isaac Perrins erected the engine to Watt's plans and direction.

The 50-inch cylinder with its 7-foot stroke was three times the diameter of Watt's experimental engine and demanded unprecedented boring accuracy. At the public trial it ran at about 14 to 15 strokes a minute and cleared the pit's standing water in under an hour, after which the workers named it the "Parliament Engine."

Not exactly a sale

These engines were not complete machines sold from a factory. Customers funded construction while Boulton and Watt supplied plans, specialized parts, supervision and a patent licence, taking a royalty of one third of the coal-cost saving against an atmospheric engine.

The contemporary report claimed the engine used one quarter of the fuel a conventional engine needed for the same power.

Another early commercial Watt engine, blowing air for John Wilkinson's ironworks at Broseley, entered service around the same time — commonly dated to the following month.

17 June 1778, off Brittany

On 17 June 1778 a British fleet under Admiral Augustus Keppel encountered a small French naval force off Brittany and ordered the French vessels to submit to inspection or follow the British fleet.

The frigate Belle Poule, commanded by Jean-Isaac Chadeau de la Clocheterie, refused. HMS Arethusa pursued her, and the two exchanged fire in the first sustained Anglo-French naval combat of the war.

The French commander reported spotting roughly twenty British warships, at least fourteen of them ships of the line, before he refused; his own ship carried 26 guns firing 12-pound shot in the contemporary French account.

Both frigates left damaged

Belle Poule reached the French coast after the fight. The badly damaged Arethusa withdrew to Keppel's fleet, and other French vessels in the encounter were stopped or captured.

The action was celebrated in France and treated as the opening of overt hostilities. Belle Poule became a popular sensation.

When the war began, exactly

No single date is uncontested. France's treaties with the United States were signed on 6 February; France notified Britain in mid-March; relations then broke; the first naval fight came on 17 June; and on 10 July Louis XVI ordered French warships and privateers to attack and seize British naval and merchant vessels.

On 18 July, American commissioners in France still reported that neither nation had formally declared war, though both navies were already fighting.

A later French royal act treated 17 June as the official opening of hostilities. The rival battle fleets met off Ushant on 27 July — a separate and much larger action.

What the sources leave uncertain

  • There is no single uncontested declaration date. The alliance was signed February 6; France notified Britain in mid-March; diplomatic relations then broke; the first naval fight occurred June 17; and Louis XVI issued offensive orders July 10.
  • On July 18, American commissioners in France still reported that neither nation had formally declared war, even though both had begun hostilities at sea.
  • A later French royal act treated June 17 as the official opening of hostilities. Thus June 17 is the best event date for actual combat, but “the war begins” depends on whether diplomatic rupture, first shots or general offensive orders are used.

1 March 1781, in Philadelphia

In Philadelphia on 1 March 1781, the Maryland delegates John Hanson and Daniel Carroll signed and ratified the Articles of Confederation on behalf of their state.

Maryland was the thirteenth and final state required, so the signing completed the Confederation and put the Articles into force as the United States' first constitution. Congress had adopted them on 15 November 1777.

Thirteen guns from the hill, thirteen from the river

Philadelphia marked the completion with artillery, a reception at the president of Congress's residence and evening fireworks. Thomas Rodney recorded thirteen cannon from a hill and thirteen from the frigate Ariel, commanded by John Paul Jones in the Delaware.

Ariel was dressed in streamers by day and lights by night. At two o'clock, legislators, officers, diplomats and townspeople crowded into Samuel Huntington's residence for a collation.

What the day changed

Maryland had withheld accession over western land claims. After New York authorized a cession and Virginia offered to relinquish territory northwest of the Ohio, Maryland's legislature completed its assent on 2 February; Congress received the certified act on 12 February and scheduled the signing.

The completed document established the constitutional style "the United States in Congress assembled," described the union as perpetual and joined the states in a league of friendship. "Confederation Congress" is a later historical label rather than a name adopted that day.

The United States and its wartime Congress already existed; what 1 March supplied was an agreed written constitutional basis. Delegates began discussing additional federal powers within days.

20 January 1783, at Versailles

At Versailles on 20 January 1783, the British plenipotentiary Alleyne Fitzherbert signed preliminary articles of peace with the French foreign minister, Charles Gravier, comte de Vergennes.

Fitzherbert then separately signed preliminary articles with Spain's ambassador to France, Pedro Pablo Abarca de Bolea, count of Aranda. The instruments say only that they were done "at Versailles"; the more specific claim that they were signed inside the palace is not established by the treaty text.

Twenty-three articles, and eleven

The Anglo-French agreement ran to 23 articles. It assigned Tobago and the Senegal River and its dependencies to France, while restoring Grenada, the Grenadines, St Vincent, Dominica, St Kitts, Nevis and Montserrat to Britain.

The Anglo-Spanish agreement ran to 11. Spain would keep Minorca and West Florida, receive East Florida, and return the Bahamas to Britain — two different verbs for two different kinds of gain.

A countdown, not a ceasefire

Britain and the American commissioners also exchanged declarations that day, extending the coming suspension of arms to the United States on the same schedule as the three European crowns. The provisional Anglo-American articles of 30 November 1782 had been expressly conditional on Britain and France agreeing peace.

Fighting did not stop everywhere at once. The cessation schedules ran from the later exchanges of ratifications — 3 February for France, 9 February for Spain — and captures made after 12 days in nearby seas, or as late as five months in distant waters, could have to be returned.

Definitive Anglo-French and Anglo-Spanish treaties followed on 3 September 1783.

8 June 1783, on a short fissure

On 8 June 1783 a brief explosive eruption opened on a short fissure in southern Iceland, and lava began pouring into the Skaftá River gorge before the day was out.

Basaltic magma had propagated through the Grímsvötn fissure swarm. Interaction with shallow groundwater produced the explosive opening phase, after which fire-fountaining and rapid lava effusion developed.

Four days later the lava had travelled 35 kilometres to the lowlands.

Eight months, 14.7 cubic kilometres

This was the first episode of the Lakagígar or Skaftá Fires eruption, which ran to 7 February 1784 and propagated northeastward along the fissure system. The completed vent complex reached 27 km.

It produced 14.7 ± 1.0 km³ of lava and released an estimated 122 megatons of sulfur dioxide. The familiar name "Laki eruption" comes from an older mountain crossed by the vent complex, not from a single cone erupting.

What actually killed people

Modern analysis finds no evidence that lava, tephra or comparable immediate hazards directly killed anyone on the opening day. Livestock in nearby parishes began dying within roughly two weeks; the famine and peak human mortality came later.

Iceland's population fell from 49,609 at the beginning of 1783 to 40,381 at the beginning of 1786 — a decline of about 19 per cent from excess deaths and reduced births, with roughly 8,000 excess deaths estimated in 1784–1785.

Studies identify excess mortality coinciding with the haze elsewhere in Europe, including an estimated 11,500 excess English deaths in August–September 1783 and 8,200 in January–February 1784. Attribution is contested, and a 2024 review concludes that the evidence for substantial direct haze-caused mortality is weak.

  • Studies identify excess mortality coincident with the haze in parts of Europe—for example, an estimated 11,500 excess English deaths in August–September 1783 and 8,200 in January–February 1784—but coincidence and attribution are contested. A 2024 review concludes that evidence for substantial direct haze-caused mortality is weak.
  • Regional weather and famine effects outside Iceland can generally be attributed only probabilistically, not as a simple count of people definitively killed by the eruption.

26 January 1788, into Port Jackson

Arthur Phillip's journal records that HMS Sirius and the remaining First Fleet ships joined him at Sydney Cove on 26 January 1788, where he intended to fix the settlement.

The transports, store ships and Sirius evacuated Botany Bay that day. All eleven ships — two Royal Navy vessels, six convict transports and three store ships — were safely in Port Jackson by nightfall.

Several collided on the way out. Friendship struck Prince of Wales, and Charlotte then struck Friendship; the convoy completed the move regardless.

Why not Botany Bay

Phillip had found Botany Bay exposed and deficient in suitable soil and reliable fresh water. Reconnaissance of Port Jackson revealed a protected deep-water cove where ships could anchor near a freshwater stream, and he chose it before the 26 January transfer.

John Hunter brought Sirius and the convoy across while Phillip was already at Sydney Cove aboard Supply. The landing began permanent British occupation on Gadigal Country, where Aboriginal people had lived for thousands of years.

The ceremony, and the dates that follow

A British shore party displayed the colours and marked possession for George III, but the surviving journals leave it uncertain whether that happened on 26 or 27 January. Philip Gidley King's journal appears to place the ceremony on the morning after the convoy anchored.

The roughly 1,500 people the fleet carried did not all disembark that day. Women convicts began coming ashore on 6 February.

Government was formally proclaimed on 7 February, when David Collins read Phillip's commission and the colony's legal instruments.

21 June 1788, in Concord

At its second session, in Concord's Old North Meeting House, the New Hampshire convention assented to and ratified the proposed federal Constitution on 21 June 1788 on behalf of the state's people.

The National Archives records the vote as 57 in favour and 47 against. Contemporary letters from Madison and Washington, and some congressional histories, report 57–46.

The ninth

New Hampshire was the ninth state to ratify, satisfying Article VII's requirement for establishing the Constitution — "between the States so ratifying", not automatically in all thirteen.

The convention's first session had adjourned in February without deciding, letting delegates bound by anti-ratification town instructions consult their constituents. When it reconvened in June, supporters won by coupling unconditional ratification with recommendations for amendments.

Twelve amendments, and a nine-month wait

The convention recommended twelve amendments intended to limit federal power and protect rights including conscience, jury trial and the possession of arms.

The ratification instrument directed convention president John Sullivan and state president John Langdon to transmit the engrossed document to the Confederation Congress, which received notice on 2 July.

The federal government did not begin operating that day. On 13 September Congress scheduled elections and set 4 March 1789 for proceedings to commence; the House reached a quorum on 1 April and the Senate on 6 April.

7 January 1789: appointment day

7 January 1789 was the date the Confederation Congress had fixed for states that had ratified the Constitution to appoint presidential electors. Those electors — not voters nationwide — were scheduled to vote for president on 4 February.

States used different procedures. Pennsylvania, Delaware and Virginia held popular elections for electors; several legislatures made the appointments; New Jersey used its governor and Privy Council. Maryland's voting continued through 10 January.

Venison at Page's Tavern

George Washington attended the elector poll in his Virginia district. He recorded that David Stuart received 216 Fairfax County votes against 16 for Thomas Blackburn, after which Washington dined on venison at Page's Tavern.

New York failed to appoint its allotted eight electors by 7 January. North Carolina and Rhode Island had not ratified the Constitution, so none of those three states cast electoral votes.

Not an Election Day

Nor was it a nationwide House election day. Elections for the first House ran on state-selected dates from 24 November 1788 to 22 June 1789.

No president had yet been legally elected. The electors voted on 4 February and Congress counted the ballots on 6 April, giving Washington 69 electoral votes and Adams 34 — 138 votes in all, because before the Twelfth Amendment each elector cast two undifferentiated choices.

Because only some states used popular selection and the surviving returns are incomplete, the Washington Papers concludes that a national popular-vote total cannot be reconstructed.

20 June 1789: a locked hall

On 20 June 1789 deputies arrived at their usual meeting place, the Menus-Plaisirs hall in Versailles, and found it closed and guarded while preparations were made for a royal session.

They walked to a nearby indoor court used for jeu de paume, a predecessor of modern tennis — a hall built in 1686 where the royal family had played. Joseph-Ignace Guillotin is credited with suggesting it.

The oath Bailly read

Jean-Joseph Mounier proposed a solemn commitment, and the Assembly's president, Jean-Sylvain Bailly, read the oath: that the deputies would not separate, and would meet wherever necessary, until the kingdom's constitution was established on firm foundations.

The oath did not adopt a constitution. It bound the deputies not merely to stay together that day but to reassemble wherever circumstances forced them.

The one who said no

Joseph Martin-Dauch alone registered opposition, objecting to an oath that might conflict with royal authority. He did not take it, but he did sign the session record as an opponent, and Bailly insisted that his dissent be recorded as evidence of freedom of opinion.

The conventional figure of 576 oath-takers simplifies a complicated attendance and signature record that included a few clergy and nobles, substitutes and later adherents.

The Assembly stayed organized despite the lockout. It resisted the king's attempt to undo its decisions on 23 June, and within a week deputies of the clergy and nobility had joined it, tacitly accepting deliberation by individual deputies rather than by separate orders.

The evening sitting of 4 August 1789

At an evening sitting in Versailles on 4 August 1789, the National Assembly interrupted its constitutional debate to consider disorder in the countryside and Guy-Jean-Baptiste Target's public-security motion.

Reports of the Great Fear described armed peasants, attacks on châteaux and the destruction of the terriers that recorded seigneurial rights. Deputies feared a widening rural revolt and the collapse of public order.

Noailles, then d'Aiguillon

The vicomte de Noailles argued that concessions to the peasantry and abolition of feudal rights, not repression alone, were what would calm the provinces. The duc d'Aiguillon followed with proposals for fiscal equality, abolition of personal servitudes and redemption of other feudal and seigneurial dues.

Deputies then proposed ending seigneurial justice, exclusive hunting rights, tithes, the sale of offices, guild restrictions and the special privileges of provinces and towns. The session's resolution recorded renunciations of privilege and the abolition of serf status and mainmorte.

This was legislative action and a run of renunciations — not a collective oath like the one taken on the tennis court in June.

What was still owed in the morning

The sitting ran past midnight, closing about 2 a.m. on 5 August. Near its close Lally-Tollendal persuaded the Assembly to proclaim Louis XVI "restorer of French liberty."

The detailed decrees followed over 4–11 August. Personal servitudes were abolished without compensation, but numerous property-related dues remained payable until redemption, and royal letters patent were not published until 3 November.
