History

Life on this Earth began to develop 200 million years ago. Within fifty million years, it had rapidly evolved into the plethora of taxa that exist today, being ruled by dinosaurs similar to those of the real-life late Cretaceous period 150 million years ago.[1] Owing to the drastic differences between the evolution of life between the real world and Earth-1610, it is unclear exactly when the dinosaurs became extinct and when humans first evolved.
More than 10,000 years ago, Atlantis and Lemuria existed as the most advanced civilizations known on ancient Earth and waged war against each other.
This war annihilated the two empires, leaving some survivors such as the criminal Namor. The Inhumans also existed at the time and remained hidden from human society in their city Attilan in the Himalayas until the present.
In the 20th century, the alien species known as the Chitauri, who had previously visited Earth in 1777, attempted their conquest of Earth. In 1904, an alien android known as the Vision landed on Earth to prepare the human race for the coming of the planet eater known as Gah Lak Tus. Due to a malfunction, the Vision's ship crashed landed in the Russian territory of Tunguska, creating the Tunguska Event, and was kept in a secret military bunker by the Soviet government. Years later in 1920, the Chitauri infiltrated German politics and set into motion events that eventually lead to World War Two. The Chitauri supplied Nazi Germany with advanced weapon technologies. The Allies became aware of this alien threat and were determined to stop it.
By this time, the United States government, under President Franklin Roosevelt, sought to create super-soldiers in the war effort. Two soldiers, Nicholas Fury and Canadian James Howlett were captured and experimented on for this project. Howlett was sent to and tested on in a remote facility that would later be known as the Weapon X facility while Fury was sent to New York to join other African-American test subjects for an experiment known as Project Rebirth.
Fury was the first successful super soldier that came out of Project Rebirth. Afterwards he used his inhuman strength to break out of the facility and free the other test subjects. At the Weapon X facility, while trying to create their own super soldier, the Canadian government accidentally created a new mutated genome. That genome would soon spread around the world and create a new species of super-humans known as Mutants.
With the success of Nicholas Fury, Project Rebirth finally chose a young and weak boy by the name of Steven Rogers, who became Captain America.[3] By 1945, Captain America was part of an operation assaulting a Nazi missile complex in Iceland, which held a hydrogen-nuclear missile and was was targeted at the American mainland. Captain America sabotaged the missile while it was taking off, and was sent into a 60-year coma in suspended animation after the destruction of the missile plunged him into the arctic sea.
Years later, Erik Lensherr, the mutant child of two scientists that worked for Weapon X, freed Mutant Zero a.k.a. Wolverine (James Howlett), and killed his mother and other Weapon X agents for what they had done to mutants. Erik left and sought out another fellow mutant, Charles Xavier. Erik proposed that they start a brotherhood formed by mutants to protect their own kind and create new lives away from the reach of mankind. Charles was later convinced by Erik's plan and the two then left their human wives and began gathering other mutants from around the world. As they traveled across an unknown land, Charles, Erik, and his children Wanda and Pietro crash-landed in the Savage Land where they meet a clan of humans. Among them were the young Ka-Zar and Shanna. Charles and Erik found this strange land ideal to their purposes and the Brotherhood of Mutant Supremacy established a secret settlement in the Savage Land. Months later, Charles grew disillusioned with the settlement as Erik grew increasingly more radical and tyrannical, and after Charles failed to lead an uprising against Erik, he attempted to flee but was stabbed by him in the spine with a metal spike. This left Charles paralyzed, but he still managed to escape the island. Weeks later, Ka-Zar and Shanna's tribes were slaughtered by Erik, now calling himself Magneto, in order to make the Savage Land a place for mutants only.
Due to the actions of Fantastic Four villain Dr. Doom (who manipulated the deaths of the Scarlet Witch, and the conflict between the Brotherhood of Mutants and the Ultimates), Magneto vengefully executed his plan in exterminating humanity through shifting the poles of the Earth, causing global natural disasters upon the world, leaving only he and his followers to survive. In the wake of Magneto's fury, millions of people died including many of Earth's superhuman heroes and villains alike. Anti-Mutant sentiment was exacerbated in America and with the majority of their members dead, the X-Men disbanded after their leader Cyclops was killed in an assassination orchestrated by the Brotherhood, now lead by Magneto's son Quicksilver. Mutants began to be arrested and shipped off to internment camps.
Shortly after the funeral of Peter Parker, a new Spider-Man, by the name of Miles Morales, had surfaced, causing confusion among the citizens of New York as to how Spider-Man is alive when word of his demise was all over the news. Miles fights Electro, paralyzing him long enough for Nick Fury to shoot and kill him. He then received Fury's blessing in taking up Peter Parker's mantle, and was given his own Spider-Man suit.
A new model of Sentinels, called Nimrod Model Sentinels, were deployed to hunt and capture, or kill, mutants who refused to turn themselves in. News hit the media that mutants were in fact the result of Super-Soldier testing funded by the American Government in Canada, and not the result of evolution. This caused riots to break out.
Having found a way to escape from the N-Zone, Reed Richards returned to Earth. Bringing together a group of highly intelligent individuals, he began his experiment. Creating the Dome, a research facility in its own time-bubble, Reed and his Children of Tomorrow began their experiments, seeking to push the limits of science.
In the S.E.A.R., scientists managed to uncover a way to create the next generation of superhumans. Releasing a virus that prevented mutants from being born in the outside world in an attempt to cripple the rest of the world's superhuman population, the SEAR began creating superhumans termed only The People en masse.
SHIELD would now be faced with disaster on three fronts. Tensions between Argentina and Uruguay escalated to the point of all out war, and the Argentines used Stark technology supplied to them by the Kratos Club to destroy the Uruguayan capital of Montevideo in a nuclear blast. At the same time, the People, the new superhumans of the SEAR revolted against their government, who requested SHIELD aid. The government was toppled extremely rapidly, and SHIELD failed to respond. Furthermore, they lost their mutant operatives lead by Karen Grant to the new nation of Tian, which offered safe haven to mutants and superpowers to any who desired them. At the same time, Reed Richards' Children of Tomorrow took their experiment to the next stage. Inside their Dome, one thousand years had now passed, leaving them enormously technologically superior to the rest of the world. They expanded to the next level, creating "The City", a supercity covering much of Central Europe, resulting in the destruction of the nations and humans already living there. SHIELD and the EDI both failed to stop this, resulting in the destruction of Asgard, leaving Thor mortal once again.
The United States was faced with conflict within as well, as mutants revolted in their internment camps, and anti-mutant militias such as the one lead by William Stryker gained increased power. After being killed by Kitty Pryde, Stryker's consciousness possessed the American Nimrod Sentinel fleet, and began outright slaughtering mutants. The fleet took over the Southwestern states of the USA, and the President was forced to abandon them, leaving them to Sentinel control. With threats on all fronts, the President launched the entire nuclear arsenal onto the City, but managed only to destroy 20% of it. In response, Reed Richards, now calling himself the Maker, launched an attack on Washington DC, destroying it and assassinating the President. Nick Fury and SHIELD sought an alliance with Tian against the City, and after the Maker killed one of the People, Tian launched an attack. The City was defeated from within however, as the Children of Tomorrow renounced the Maker, and turned him over to US custody.
The collapse of the United States continued however. With central control waning and the Southwest lost, Texas and the West Coast also seceded from the union. Nick Fury was also once again dismissed from SHIELD and continued to operate on his own.
