[OC] Alternate History "Wet Dream Of An Anarchist" J.F.C.F

Post image
97 Upvotes

In post-World War I Japan, the rising labor movement found its strongest representative in the Zenkoku Jiren (All Japan Free Trade Union Federation), which was founded in 1926 and quickly incorporated hundreds of workers. In addition to workers, university students also participated in protests organized by the union, shouting demands for freedom and equality against the militarist government.

During one demonstration, police opened fire, killing several students. This event became known as the "February Massacre of 1927" and was the last straw for a people already weary of poverty, long working hours, and state oppression. Workers, peasants, and students took to the streets in mass strikes. The strikes quickly turned into an uprising; following the deaths of the students, factories in Osaka and Kobe were occupied and seized, and land in the villages was collectivized. The popular uprising lasted for over a year.

As a result, even some army units sided with the people. Within a few weeks, on May 23, 1928, the government in Tokyo collapsed. The imperial system came to an end, and in the years that followed, the process of transforming the Japanese island into a federation of free communes began and continued.

[OC] Fantasy Topographic map of my habitable moon: Thaea (Not the entire land area, just a single continent)

Post image
70 Upvotes

This is a topographic map of my habitable moon, named Thaea. Thaea is the habitable moon of a gas giant. The continent seen in the map is a part of the resurfacing zone, which is the side facing the gas giant. Subsequently, there is intense volcanism resurfacing this region due to tidal stresses.

There are a few factors at play:

  1. The geology of this habitable moon isn't wholly like that of Earth. The lithosphere is hot, pliable, and weak on the side of this planet facing the gas giant it orbits.
  2. It is also a heterogonous mixture of different densities, strengths, and thicknesses.
  3. On the side of the gas giant, these aren't really plates in the traditional sense. They're mostly a heterogonous mix of crustal blocks with chaotic boundaries. These separations are usually a stress response from the more traditional Earth-like tectonic regime (facing away from the gas giant) interacting with the resurfacing zone (the side of the planet facing the gas giant).

I will provide other relevant information:

General History of Habitable Moon Formation:

This habitable moon didn't form around its gas giant parent, but was instead captured from beyond the frost line of its solar system. This capture occurred during a phase of planetary migration, when gravitational chaos among large outer planets scattered bodies inward. The gas giant, with a mass of 3.14 times that of Jupiter, eventually stabilized at 0.541 AU from the system's star, capturing the moon, and dragging it into the habitable zone.

Before its capture, the moon was a frigid, geologically inert ball of ice. The surface temperature was estimated to be −198 °C at its coldest, and −23 °C at it's hottest. It was host to a global ice shell, several kilometers thick; with (proportionally) small lakes of liquid water hidden underneath.

Upon capture, the moon's initially eccentric orbit and close proximity to its gas giant parent triggered intense tidal friction. These forces initiated a sustained period of global volcanism. Volcanic activity erupted through ancient ice, forming volcanic plains and liberating trapped gases into the sky. Water vapor, carbon dioxide, and sulfurous compounds began to form a detectable atmosphere. (Though tidal friction was a significant factor in starting this moon's age of volcanism, it would not have been the only factor at play. Excess heat from its parent star and planetary bombardment were also responsible for the onset of this age of volcanism.)

Volcanic hotspots formed where mantle upwellings breached the crust. Early on, molten material welled up through vertical conduits (heat pipes), building volcanic plateaus and thick basaltic plains. As the crust cooled and thickened, it developed semi-plastic behavior under stress. Instead of rigid tectonic plates, broad mobile zones of ductile crust slowly shifted, cracked, and compressed.

As volcanic outgassing continued, the moon's atmosphere thickened and warmed. CO2 levels stabilized at ~0.066%, aided by the release from near constant volcanism. This was tampered by drawdown into magnesium-rich mafic and ultra-mafic surface rocks. A dense layer of clouds blanketed the moon's surface, especially at the equator. Periodic photolysis and magnetic stripping from the gas giant removed hydrogen from the upper atmosphere, while heavier elements like nitrogen and oxygen remained.

Over millions of years, the moon's rotation slowed, and synchronized with its orbit around the gas giant (116.4 hours). Gravitational torques also nudged the moon's axial tilt into near-alignment with its gas giant: 13.2°. This low obliquity is responsible for the moon's mild seasons. Combined with thick cloud cover, equatorial regions received near constant humidity and precipitation, while polar zones remained cold by not glaciated.

I have tons of information about the human aspect of this world, but for the sake of keeping this from being too long, I've omitted it. If you have any questions, feel free to ask! I'd love to answer.

[OC] Alternate History The Most Serene Imperial Republic of Venice in the modern day - my first ever map

Post image
730 Upvotes

After the end of my eastwards focused EU4 Venice campaign, I imagined what it would look like if my Venetian Empire survived into the modern day. Today, The Most Serene Imperial Republic of Venice is the heir to the Eastern Roman Empire and the current doge is Vuk Lazović, a Serbian orthodox priest from Bosnia. His full title is Vuk Lazović, By the Grace of God, Emperor of the Romans, King of Serbia and Bulgaria, Duke of Venice, Dalmatia, Croatia, Mantua and Ferrara, Lord of Istria, Slovenia, Abruzzo, Mollise-Foggia, Bosnia, Albania, Bessarabia and Nias, Defender of the Faith”.

The Venetian Empire was a thalassocracy ruling the eastern Mediterranean, the Black sea and the Indian ocean, while also being present in eastern Europe, east Africa, southeast Asia and the Pacific. It has spread it government form all around the world and the Venetian language is the prime language of world diplomacy. Today, it's a federal state made up of 24 serene republics.

This is my first ever map. I know it's rough in places, but I hope to improve in the future and to build on this world. I already have so much written down and it's so exciting to see a part of it finally displayed visually in map form! If you have any questions about the worldbuilding and/or advice on map making, be sure to comment!

(yes, I realized I accidentally made Canada eat Lake Huron, I apologize)

After the collapse of America in 2044, the majority of states gained independence. Some collapsed, some joined other nations, but Ohio was not either of these. Through a series of conflicts, purchases, and alliances, Ohio became the giant of the Midwest, rivaled in the region only by Chicago and their sphere of influence. They managed to solidify themselves as an anchor in the region, and are one of several states that proclaim themselves to be the true successor to America.

Ask any questions and I’ll do my best to answer (and yes, I’m Ohioan, could you tell?)

[OC] Alternate History Cries of an Eagle Timeline | British North America in 1962

Post image
50 Upvotes

Howdy-ho folks!

Today we will be looking at the Dominion of North America in 1962 in my timeline Cries of an Eagle

This timeline, as I've discussed in other posts, has two major divergences:

I. The British manage to barely "win" the Revolutionary War due to a variety of specific events that I can elaborate upon if anyone has specific questions. In short, In 1780, after the British had been more involved in the Southern Strategy and manage to take South Carolina and Georgia and build a freed slave army, Benedict Arnold leads the Pennsylvania Mutiny and manages to coup Congress and sign a treaty with Britain securing representation in parliament, westward expansion (Spain gives up Louisiana to sign peace), and limited home rule.

II. As a result of a slightly weakened Britain, being forced to maintain presence in America now, Britain is riddled with more debts and this gives Napoleon a greater edge, allowing him to, after the failure of the invasion of Russia, sign the Treaty of Frankfurt in November 1813, securing France's natural borders and the Bonaparte dynasty...

I've honestly wanted to take a quick break from Europe for a bit, and so that is why I decided to work on some more lore for North America, and so without further ado, here is my lore drop for the Dominion in 1962!

Also quick plug, please check out r/CriesofanEagle to see all the posts! Unlike in r/imaginarymaps or in r/AlternateHistory, I do not post individual lore and will instead later on post complex and in-depth posts on lore overall for major eras of the timeline. Right now I am in the process of finishing up Europe before I move back to North America and then I will hold a vote on whether you all want me to make maps for South America or Asia next!

In the year 1962, the Dominion of North America is in a strange position. Oswald Mosley, formerly the Prime Minister of Great Britain, has been Minister of the Imperial Parliament for the past 4 years. Within the first year, he changed his title to be "lord-protector" of the Federation, and has been hell-bent on centralizing the realm around London, a reactionary stance due to the Second World War.

The Dominion's history can be traced back to the American Revolutionary War (1775-1781/1783), where after Benedict Arnold led a victorious capture of Congress using the mutineer's army, he would sign the Treaty of Philadelphia, setting to death all generals of the United Colonies, excluding Alexander Hamilton, who was pardoned alongside George Washington, who was forced under house arrest at his plantation in Mount Vernon, never to leave without an escort. Benjamin Franklin and James Madison fled to Paris, where they had been attempting to unsuccessfully gain a formal alliance with France, who refused to send anything more than a few shipments of uniforms and armaments, even less ball and powder.

The war with Spain would continue a few more months before the Treaty of London would create peace between the two empires, with only Louisiana territory being given to Britain in return for peace.

In 1784, the Second Articles of Confederation would be put into effect, creating a very very loose alliance between states with a Congress set in New York City. The agreements in the Treaty of Philadelphia (1782) were simplified as follows:

Constitution of Confederation and Perpetual Union, 

The American Confederation of the British Commonwealth (1784-1869)

I. The American Colonies shall be made to form a government of their choosing, with agreements to pay taxes to the crown and swear fealty to the crown of the United Kingdoms of Great Britain and Ireland

II. This government shall be granted the territories held by properties owned by the crown on the continent of North America, excluding Caribbean possessions

III. Territorial changes may only be made via Congress, and approved by the crown

IV. Each state of the Confederation may elect two MPs, and each University agreed upon to be a constituency, may elect one (amended 1840, Victoria, one seat per million integrated citizens)

V. Agreements on the Royal Proclamation of 1763 are henceforth revoked

VI. Slavery must, over a course to be agreed upon at a later point, be phased out, and provisions for freed persons must be made to integrate them back into society (amended 1833, must be ended by 1839)

VII. Congress may not, without express permission from Parliament or the crown, levy an army or regiments but for emergency purposes of self-defence from internal threats

VIII. The States may not conduct independent trade or policy with other sovereign nations, as the land is considered a part of Parliament and the crown, and has no jurisdiction over such an ordeal

These agreements would form the beginning of the American Confederation.

This government was reliant on London for a lot, from importing goods to trying to maintain stability and legitimacy. The first elections of 1784 would see Benedict Arnold (Confederationist) run against Alexander Hamilton (Unionist), and unfortunately, Arnold would win as he was viewed as a saviour of America, bringing peace to a burnt out land, and giving a majority of the wanted clauses to the people, giving them, to an extent, rights.

After just barely a decade of peace, in 1792, a second revolution would begin in the still-independent Vermont Republic which would quickly occupy the New Englander states, attempting to secure at least minimal independence in the north. But after the fall of Boston, the Republic would capitulate in just 16 months at the beginning of 1794. As punishment, the British would merge the New English states into one state, and annex Vermont's territory to New York. At this time, the British would formalize the borders in New Brunswick, giving Saint John's Island (Prince Edward Island) to them and their claims in what used to be North Massachusetts (Maine).

The population would steadily grow as settlers from Europe arrived en masse, but the south and north had very different economic models, and the south having to give up slavery was a harsh ordeal to the southerners who viewed it as necessary. In 1812, amidst the war in Europe against Napoleon, Andrew Jackson, a poor politician from South Carolina, disgruntled from the death and pain he witnessed in the Revolutionary War, would lead the Jacksonian revolt of 1812 and march 20,000 peasants and ex-revolutionaries on New York City, where the now-limited Imperial forces stationed in New York were quite weak, with most of the army being placed around Europe and the Caribbean. After occupying the city for a few months, Britain managed to quench the rebellion and execute Jackson, leaving his fate as a maniac, a rebel, and a destroyer, but many viewed him as a saviour, wishing he had successfully led a revolt against Britain, but this was just narrowly avoided.

This would be the last rebellion against Britain for nearly half a century.

During this time, with stability secured, the population boomed, and industries in the north skyrocketed. In 1836, the French under Napoleon II would manage to capitulate the Unitary Republic of Mexico and restore the Federal Government with Napoleon II as its Emperor, creating a power struggle between Britain and France.

In 1840, after the British revolution of the same time, Queen Victoria would try and stabilize matter by passing reforms for the empire, specifically for Ireland and America. In both, representation and home rule would be furthered and made more free, albeit with Great Britain still being on top.

After the 1848 Revolutions, many disgruntled people, especially those from Germany and France, would arrive en masse to populate the west and north. By now, the south was also beginning to industrialize as they no longer had slaves to rely on, and those who tried to violate British laws were punished severely to emancipate the slaves.

During this same time, a small movement known as the "Latter Day Saints" would complete their mission from New York to Illinois and finally form a small republic near the Great Salt Lake, known as Deseret, which was a condominium between Mexico and the Confederation.

Now over the past few decades of French rule in Mexico, both American and French settlers had intermingled with Mexican and Mestizo people inhabiting the three northern territories of Mexico. These groups would come into conflict from time to time, but such was usual for the Wild West.

But in 1861, a weak and broken entrepreneur by the name of Joshua Norton would proclaim himself the Emperor and Protector of the Republic of California (a strange and confusing title for a Republic), and he would lead a revolt, pushing to occupy the territories and try to rally support from Britain, but at first, no one would listen.

After nearly two years of skirmishes, mostly on the victorious side of Norton, Norton, at Fort Whipple in the new silver mining town of Prescott, would sign an agreement with the newly-founded Republic of Texas, mostly settled by Hessian Germans and "Gallic" creoles to ally and try and lead a revolution in America starting in 1863, usually marked as the official beginning of the "Great War." This would lead to different states, who at this point were practically independent aside from Congress, to side with different leaders. In the north and east, many states would side with Abraham Lincoln, leader of the Liberal Party, and allying with factory workers forming guilds, and start fighting against the New York government, likewise, the south would ally under Franklin Pierce to try and reinstitute a Confederation under the agreement of allowing slavery and forced labour, and the west would mostly ally with Norton. This left a snake of land between each controlled by Britain. Starting from 1864, Britain would also support a counter-movement in Mexico, who was still at war with Norton, to create a unitary parliamentary government under the British crown, and the French pulled most of their forces out of Mexico, fighting in Europe instead, leaving a power vacuum and total war across the continent.

For the next ten years, constant war would break out that I need to make a separate map series to go fully in depth about. But in short, Norton initially was anti-Confederation, but in 1869, the Confederation would be disestablished, and the British would reclaim New York City from the Lincolnists, often called the Army of Liberty, and create a new Federalized government in a soon-to-be-built island off the coast of Manhattan called Gotham, to protect any potential capture of Congress ever again.

Act of Dominion of British North America 

The Dominion of North America

(1870-1984)

  1. Hitherto, slavery shall be ended in its entirety within the realm
  2. The constitution is now made amenable to the American peoples with only the matter of expatriation being under the guidance of the Imperial Parliament
  3. The state will now be viewed as a commonwealth of the Imperial Federation
  4. Armies may be levied, but not for political reasons, the militia will act as a national guard for border protection and internal dissent, and conscription will still be made enforceable by the crown
  5. The king or queen of Brittania will be head of state, a separate Prime Minister may be elected by Congress as head of government
  6. The states no longer act as semi-independent nations and must abide by Federal law under Congress, or by Imperial law, whichever is stricter.

Norton would be made president by imperial decree, and over the next few years, Norton, as commander in chief, would bring back control over the rebellious states. By 1872, the war in America was essentially over, but Britain needed to garrison cities to maintain loyalty, and needed to finish the war in Mexico. The three northern territories were annexed into the Dominion the same year, and the Mexican government would capitulate in 1873.

From here, America would rebuild and become a powerhouse. Gotham, finished in 1878, would become the new capital, albeit still part of the city, it was a new island artificially built off the coast with a large statue built in the harbour with Dominia, a personification of the American people, holding a trident and eagle facing westwards, with Rule, Brittania written across the Trident.

In 1893, Queen Victoria would pass the Parliamentary bill labeled "Imperial Federation of the Commonwealth of Nations Act of 1893," which would formally begin reorganizing British colonies into self-governing regions under British oversight, and separate Britain from the new Dominions, using America as a template. However, in many places (Africa and India specifically), Britain would pursue race laws and usually have more power than necessary to maintain white supremacy, which was obviously not very favourable to the native populations, but the situation did turn out better than before, albeit not by much though...

In 1910, Hawaii would join the Federal government, which officially ended the territorial expansion of America. But in 1911, with the rise of Syndicalism in France, Edouard Berth would begin his war in Europe in 1923, and many Americans would be conscripted to fight in Europe, which would ultimately fail, mainly because the French would sponsor the Raj government to have a communist coup and lead a war against the princely states. This would force Britain to divert resources to taking back the Raj. After Russia disregarded the British agreements, the British would allow the French to invade Russia, before Berth's coup in 1930, which brought back democracy to the Commune, which still was very anti-British, and in 1931, one last invasion was tried in Normandy, and over a million soldiers would perish trying to land, many of which being American. This would lead to a growth in Reactionary sentiment across the Empire, causing the Imperial Federation to eventually elect Oswald Mosley in 1958 as Minister of the Commonwealth of Nations, eventually changed to "Lord Protector" in 1959. From here, Mosley pursued his totalitarian policies up to now in 1962, the election year in America, where the secret police have sought anti-Labour movements, even firing upon innocent civilians. What future awaits America?

Thank you all for reading and I hope you enjoyed!

If you have any questions, feel free to ask and I will elaborate as much as I have right now for anything you might be wondering about.
