Prehistory: Several figures rise in various lands, triggering legends that snowball into full-fledged mythologies.
5000 to 2500 BCE: The Egyptian dynasties are founded by what many scholars believe are the first metahumans: the god Ra and his disciples.
2700 BCE: The Sumerian king Gilgamesh builds the walls of Uruk in twelve days and twelve nights - single-handedly. His legend has since been changed, but all current evidence leads experts to concur he was one of the first recorded metahumans.
1300 to 1200 BCE: Heroes (who would be the equivalent of the modern day super-hero, only without masked counterparts) of Greece and Troy clash. It is believed by metahuman scholars and experts that inspiration for the Greek Dodekatheon and it's similar counterparts throughout the world came from very well-connected, very powerful superhumans.
1000 BCE to 1000 CE Masked crusaders and other heroes are mistaken for avatars of the gods in South Asia. This trend will continue until the modernisation of the world, or around the Industrial Revolution.
60 BCE to 17 CE: Roman expansion makes extensive use of metahumans to conquer much of the known civilised world. The fall of Caesar is occasionally attributed to a mysterious Man Behind the Curtain, though little evidence suggests this has much to do with superhumans.
474 CE to 516 CE: A man now known as Arthur seizes power in a small region of what is now the United Kingdom with the help of the believed mutant Merlin. Though the story is still believed to be myth by contemporary historians, those willing to believe and search the area of his former utopian kingdom are constantly finding new and astounding evidence to suggest Camelot was more than just a fable.
732 CE —: The Christian church suppresses metahumans and other exceptional individuals, except in few, related cases (most of which involve espionage for His Holiness the Pope). Elsewhere, heroes are silenced for various other reasons - mostly political.
1078 CE to 1102 CE: Robin Hood prances around central England, fighting for the poor. Or himself. Or both.
1500 CE —: Most super-heroes work through legacies of secrecy and any mention of them by this point is regarded as little more than ignorant folklore. The first superhuman teams are believed to be formed in this time, the first being The Civilised Men - a group of dedicated metahumans devoted wholly to furthering the agenda of an as-yet unknown leader.
1500 to 1650 CE: Many legendary Japanese mythological figures such as Momotarō and Kintarō are seen and written about, perhaps the first metahumans recorded in Japan and the Pacific.
1620 to 1870: Slavery in the Americas is rampant, and many foreigner's religions are reignited by metahuman abilities again interpreted as holy (or unholy) avatars.
1690 to 1702: The Salem Witch Trials hysteria spreads throughout the colonies, and many metahumans are burned at the stake, pressed, hanged, or jailed indefinitely for witchcraft.
1775: The beginning of the American Revolution, a long, difficult series of battles that raged for many years, until the colonies gain independence with significant foreign aide. Famous guerrilla fighters like Francis Marion are believed to be just a few of numerous superhuman participants on the American side. The English also cease suppression of their metahuman population. They will eventually employ them in battles against other metahumans.
1811 —: Hushed, covered-up battles between various governmental superhuman groups (starting with the War of 1812 and continuing thereon) are waged in secrecy. None are recorded in official history books, but all wars featuring major powers at the time did have secret metahuman battles in addition to baseline warfare. The nation of Canada emerges as the foremost metahuman-producing country, and is kept out of major battles as a result.
1861 to 1865: Perhaps the most inventive use of superhumans in battle, The War Between the States (American Civil War) utilized immensely powerful metahumans to turn the tide. The Union of the United States Army was victorious largely in thanks to the expert plannings of the possibly-superhuman Abraham Lincoln. His subsequent death is one of the foremost metahuman conspiracy theories.
1914 to 1918: The first World War sees the increase in technology, and finally gives baseline humans a competitive edge against metahumans. The new technology allows the otherwise superhuman-deprived nations (such as Austria-Hungary) to be major (if small) contenders in all war-fronts.
1931 to 1945: The German government is said to commit controversial (and as-yet unproven) genetic experiments, attempting to make super-soldiers in the coming second World War. France and England's growing metahuman population proves no match for the military juggernaut that was the Axis forces. Eventual aide from foreign superhumans does little to help, and the conflict eventually (for the first time in over 120 years) becomes more about numbers and technology than selective, secret, superhuman warfare. The ensuing American superhuman aide helps, but the war is ultimately won thanks to the baseline men and women who fought for their freedom.
1945 to 1991: The Cold War between the American superpower and the Socialist Republics of the world is waged secretly between government employed metahumans. Though little collateral damage occurred, much of the general hostility was directly tied to metahuman battles either unknown or suppressed to the public. With the fall of the Berlin wall, superhumans finally call a peace treaty.
1961: Comic books featuring fictional superhumans begin publishing at an astounding rate, though reports of actual superheroes remain only whispers and mocking rumors.
1987: The Canadian government releases classified information regarding the use of metahumans. Several other governments follow.
1989 - 1992: Canada's Scarlet Eagle highhandedly stops hundreds of terrorists under the employ of J's Crew from taking over the city, finally cementing the fact that heroes and villains exist in the world. He begins appearing on radio talk shows and television slots.
1992 —: The media loves the supermen-and-women saving the world. The most famous among them have massive contracts and endorsements. The public, with almost no exception, adores them.
1994: Denmark establishes the Standby High-Readiness Brigade, a team of European superhumans ready to defend the nation and the world if a global threat breaks out.
1999: The United States of America passes the Masked Act (formally the Making America Safer through Knowledge and Evidence Decreed Act of 1999), which allows humans to fight crime as masked vigilantes assuming they register their secret identities with the United States. Many heroes disagree, and migrate to Canada or Europe, but the few that do stay are not outed as most feared.
September 2001: The Twin Towers in New York fall, and though some are saved from death, the events and ensuing demise of American hero Liberty Lad further prove America is in desperate need of superhuman defenders.
2003 —: The Office of Metahuman Affairs is established under the Department of Homeland Security in the United States. It, along with most advanced countries, oversee both foreign and domestic superhuman efforts with help from various international metahuman liaison offices.
2009 —: The United Nations establishes the Superhuman Unit for the Protection of Earth, or S.U.P.E.s, the first government-sponsored superhuman team. They are lead by the world-famous Scarlet Eagle, renamed The Swan. Though numerous other super-teams exist, the S.U.P.E.s represent the first transcontinental, multinational, internationally-funded team.
