I am going to make a timeline
1763-1775.
Seven Years War ends. Canada is largely destroyed by this conflict. It also almost bankrupts the British Crown, which overtaxes the colonies in a desperate attempt to pay its debts. The colonists get enraged over this and many of them start tax protests and attempt boycotts of British goods. The Governor of Jamaica attempts to explain why Jamaicans should pay for harboring British soldiers, much to the disgust of the colonists in Jamaica. Hamilton writes treatises on the tyranny of British rule in not just the Caribbean colonies, but all the other North American ones as well. The Caribbean colonies largely follow the lead of Jamaica due to similar cultures and economies. The Quebec Act fails to pass in Canada, causing resentment for the British to further rise due to fear that the British were not protecting their culture adequately. Increasingly, promises of freedom of religion cause many of the residents of the Quebec to have sympathy with the other colonists. In addition, the Canadian Colonies and their people were already furious that their overlord (Britain) could not prevent the French from destroying large amounts of their land. A "stabbed in the back" myth arises in Canada, where people blame the British for foot-dragging and using them as their front line. The American colonies (original 13) say to the Canadians that they could join and make something bigger and help fight against their British overlords. As more of the "taxation without representation is tyranny" protests engage, more anger about the settlement laws to avoid angering the Native Americans emerges, and most of all, protests about harboring the British troops who were considered terrible and incompetent, the sentiment rises to a fever pitch. The British attempt to crack down on this growing rebellion, and the first battles of the North American Revolution are fought.
1776-1783.
Declaration of Independence and its convention. Representatives from all the colonies join. The Declaration of Independence is written, and the anti-slavery clauses were taken out due to the need to keep the Caribbean, Georgia, and the Carolinas on board. The slavery issue would be solved later, though a ban on the importation of slaves receives broad support among most of the colonies. The British retake the Caribbean relatively easily, but it diverts troops from the other areas of the war. The British Army is stretched thin between the newly-formed American states (in OTL's USA and Canada) and after much frustration where it is unable to capture or kill the leadership of the rebellion, faces very low war support at home. The American soldiers in the Continental Army modernized by Von Steuben use new tactics and hold their own against the British Army. George Washington, among many others, becomes a hero in the War for Independence. France joins in to make Britain look incompetent and weaken it, helping the Americans. The French Navy arrives, which forces the British troops in the Caribbean to scramble to deal with the new threat. The British are forced out of the Caribbean as a result. The British soldiers in Canada also The American Revolution ends at the Treaty of Paris where the United States is formed and recognized. British soldiers are forced to pull out of North America, including the Caribbean. There is widespread fury in Great Britain at the King and Parliament about their ineptitude at losing the colonies. This causes a collapse in government and movement of power away from the King. Many of the old Members of Parliament lose their seats. The Dream of a Colonial America died, so Great Britain attempts to shift its focus on India and China. In the newly-formed United States of America, work begins on forming a republic and repairing the damage incurred in the War for Independence.
1786-1800
The Articles of Confederation are a failure. Work begins on the USA Constitution and once again, members of all the states (all colonies became states at the Treaty of Paris) decide to join. The Constitution is completed as OTL and it is ratified with all but some of the Caribbean colonies ratifying it. 1-13 same OTL. 14. West Florida. 15. East Florida. 16. Nova Scotia. 17. Quebec. 18. St. John's Island. 19. Jamaica.
After seeing the results of the Constitution, the other Caribbean colonies sign on two years later. George Washington is elected as the first president as per OTL, and serves two terms only. Thomas Jefferson starts building an apparatus to which to run for President. Adulation of George Washington due to his personal charisma, political skills, humility, and mental fortitude was very common. The westward expansion continues, with some attempted purchases of land from Spain in modern Florida. Discussions over this purchase would not be finished until the late 1810s. In 1796, Thomas Jefferson defeats John Adams in a very close election. The expansion of civil rights begins as Jefferson attempts to get the nation to live up to its founding promises. The translatlantic slave trade is abolished during this time, as its support had dwindled even in slaveholding states. Slavery becomes restricted to Virginia on down. Westward expansion also continues, as the settlement of Kentucky, Tennessee, and Ohio and their conversion into new states. Settlement of Western Canada also starts, but due to the lower population of the states there (OTL's Canada), it takes far longer. Over in Europe, the French Revolution rages. The Americans attempt to support the Revolutionaries, but withdraw some of their support when they start seeing just how bloody the Revolutionaries want to go. The relationship between France and the United States of America worsened as American ships started sinking and their crews taken hostage. France and Britain were blamed for this. As the U.S. refused to acquiesce to French demands in the XYZ Affair (the French diplomats did not use their real names, instead using X, Y, and Z), the Quasi-War eventually happens. Both sides are unwilling to formally declare war on each other since the United States of America was still tired of war ever since having its independence recognized, and the French being rather busy in Europe due to the wars against other European powers, most of which tried to prevent the French Revolution from spreading, and also to avenge the beheaded Louis XVI. Deals with the Native Americans are made, but they are suspicious due to the rising tide of western expansion. This Quasi-War leads to the creation of the U.S. Navy and the settlement of claims that veterans of the North American Revolution had. The Whiskey Rebellion fails horribly. Work on building a functioning economy continues. The initial rush of Patriotic fervor causes the renaming of several towns and cities that were named after Kings or other British figures to be renamed to Independence figures. Bringing democracy to (at this point, white men) was popularized and there is even some antislavery talk where the spread of slavery was successfully halted due to the outsized role and charisma of Thomas Jefferson.
1800s: I will be combining this with my "The Insanity of a Perfect Union" timeline where Britain goes down in flames sooner. Stay tuned for more!
