Chronology of the Terro-human Future History

"The only difference is that I can usually remember where I've read something in past history, but my future history I know without knowing how I know it."
— Edward Chalmers (H. Beam Piper), "Edge of the Knife"

A work-in-progress chronological complilation of future historical events from the stories and novels of H. Beam Piper's Terro-human Future History.

Atomic Era (AE) Century

1st - 2nd - 3rd - 4th - 5th - 6th - 7th - 8th - 9th - 10th - 11th - 12th - 13th - 14th - 15th - 16th - 17th - 18th - 19th - 20th - 21st - 22nd - 23rd - 24th - 25th - 26th - 27th - 28th - 29th - 30th - 31st

"The Atomic Era (AE) is reckoned as beginning on 2 December, 1942, Christian Era (CE), with the first self-sustaining nuclear reactor, put into operation by Enrico Fermi at the University of Chicago. Unlike earlier dating-systems, it begins with a Year Zero — 2 December, 1942, to 1 December, 1943, CE. With allowances for December overlaps, 1943 CE is thus equal to the Year Zero AE, and 1944 CE to 1 AE, and each century accordingly begins with the 'double-zero' year, and ends with the ninety-nine year.
"Dates AE and CE are converted by adding or subtracting 1943; thus 1964 CE is 21 AE, and 1066 CE is reckoned as 877 PreAtomic (PA). Atomic Era dating did not become official until 2nd December, 2143, or 200 AE. The Gregorian calendar, with all defects, was adopted, merely setting back January 1st to December 2nd. It took about fifty years for everybody to agree to it, and some fanatical relgious sects opposed it to the end of Terran Federation history."*

The Early Federation Era

The Early Federation era stretches from the First Century, A.E., prior to the establishment of the "First" Federation, through, somewhat arbitrarily, the mid-Seventh Century, A.E., when the "Second" Federation begins to enter a period of stagnation. The Atomic Era begins with the first self-sustaining nuclear fission reaction, on "the First Day of the Year Zero [December 2, 1942, C.E.], when Enrico Fermi put the first [nuclear reactor] into operation. . . ."^[WC] "The Edge of the Knife," the first yarn in this era, "about a history professor, who got his past and his future confused, and had a lot of trouble as a result," takes place on the eve of the Thirty Days' War — the Third World War — and of the establishment of the "First Federation," a confederation of nation-states — created after the dissolution of the United Nations — which was victorious over another alliance of nation-states, the Eastern Axis, in the War.

The Northern Hemisphere, where most of the combatant nations were located, suffered extensive nuclear devastation during the Thirty Days' War. Many refugees from the Northern Hemisphere fled to the Southern Hemisphere while the First Federation seized control of Antarctica and resettled many of its own people there. Eventually, as mentioned in the third yarn of this era "When in the Course —," efforts began to reclaim the devastated areas of the Northern Hemisphere and to aid — or pacify — Northern Hemisphere survivors who had reverted to barbarism.

Settlement of Luna, which had begun before the Thirty Days' War, expanded. Within two decades of the War, the First Federation sent an expedition to Mars. As recounted in the second yarn of this era, "Omnilingual," the Cyrano Expedition discovered an extinct, ancient Martian civilization, the first evidence of extraterrestrial sapience. Subsequent exploration led to settlements on Mars, Venus, in the Asteroid Belt and on the moons of Jupiter.

Under construction

The first worlds to be settled in the early Federation era were worlds within the Sol System itself which could be reached without faster-than-light travel.

With the advent of the faster-than-light Dillingham hyper-drive, the early Federation began to explore and settle worlds in other solar systems.

In the final years of this era, a joint Navy-Colonial Office expedtion seeking potential planets for colonization encounters the Svants of Svantovit in the yarn "Naudsonce."

The Later Federation Era

Image - Junkyard Planet cover illustration

Illustration by Herb Mott

The later Federation era begins, somewhat arbitrarily, in the mid-Seventh Century, A.E., when the "Second" Federation begins to enter a period of stagnation and ends with the Eleventh Century, A.E., when the Terran Federation has "completely vanished."^[FH] The first yarns of this era are the trilogy of novels — Little Fuzzy, Fuzzy Sapiens and Fuzzies and Other People — which describe a series of conflicts on the frontier planet Zarathustra sparked by the discovery of the native — or maybe not — "Fuzzies," disputes over their status as sapient non-Humans and the political and economic implications of the resolution of that dispute (in favour of the Fuzzies).

The next story of this period, "Oomphel in the Sky," is about a conflict between the religious beliefs of the population of sapient non-Humans on the frontier planet Kwannon, the economic interests of the charted company which exploits the natural resources of the planet (using the labour of the native Kwanns) and the political interests of the local colonial government.

In both of these later Federation era yarns, the Federation is not exploring or settling new planets. Instead, the conflicts are those between various groups — including native, sapient non-Humans — on already-settled planets.

The final yarn of this era, begun in "Graveyard of Dreams" and expanded upon in Junkyard Planet, takes place on the Federation world Poictesme and the other worlds of the trinary Gartner Trisystem where Poictesme is located. Focused primarily on the search for a fabled super — or "cosmic" — computer, the story unfolds into an emerging conflict between Poictesme (and similar planets of the Federation periphery) and the Federation itself that ultimately presages the end of the Federation two centuries in the future — in the early period of the Space Viking Era.

The Federation was no longer exploring and settling new worlds in the later Federation era. The stories of this era are focused on conflicts on settled worlds, whether with Indigenous sapient non-Humans, among competing groups of settlers on a world, or even with the Federation itself.

The Space Viking Era

The Sword-Worlds are those twelve planets settled by the descendants of System States Alliance refugees who fled Terran Federation space with the remnants of the Alliance navy at the end of the System States War. The planets' "names were a roll-call of fabulous blades of Old Terran legend."^[SS] Eventually, the Sword-Worlds gave rise to the Space Vikings who returned to raid the worlds of the Old Federation, the remnant of Terran Federation civilization which remained after a series of insurrections and conflicts known as the Interstellar Wars.

In Piper's novel Space Viking, the planet Excalibur is identified as the original Sword-World: "at the end of the Big War . . . [ten] thousand men and women on Abigor, refusing to surrender, had taken the remnant of the System States Alliance navy to space, seeking a world the Federation had never heard of and wouldn't find for a long time. That had been the world they had called Excalibur."

The grandchildren of those who had settled Excalibur went on to colonize the planets Joyeuse and Durendal and Flamberge. Additional Sword-Worlds were colonized in the next generation, including the planet Haulteclere, colonized from Joyeuse. Settlers from Haulteclere went on to colonize the planet Gram. Only four additional Sword-Worlds — Colada, Curtana, Morglay and Tizona — are mentioned by name in the novel. (An eleventh Sword-World, Quernbiter, is mentioned in Piper's novella "A Slave is a Slave," set in the time of the Galactic Empire which followed the Space Viking era. The name of the twelfth Sword-World remains unknown.) At the time of Space Viking, there are "three and a half billion [Sword-Worlders] spread out on twelve planets."

In "A Slave is a Slave," the Sword-Worlds are remembered as having been "settled by refugee rebels from the System States planets. Mostly they had been soldiers and spacemen; there had been many women with them, and many were skilled technicians, engineers, scientists. They had managed to carry off considerable equipment with them, and for three centuries they had lived in isolation, spreading over a dozen hitherto undiscovered planets." In Piper's later Empire-era yarn "Ministry of Disturbance," the historical Sword-Worlders are remembered as having "lived in isolation, spreading over a dozen hitherto undiscovered planets."^[MD]

The Sword-Worlders, venturing from Space Viking base-planets like Dagon, Hoth, Jagannath, Nergal, Xochitl and Tanith — established in Space Viking, are not the only interstellar wayfarers in the Old Federation. The Old Federation may have fallen largely into barbarism but there remain nearly "a dozen and a half planets . . . that still have hyperdrive [and] which had maintained the culture of the Terran Federation uninterruptedly." Among these "civlized planets" are Marduk (which figures prominently in Space Viking), Aton, Baldur, Ishtar, Isis, Odin and Osiris. At least two other planets, Gilgamesh (home of an obscure religious sect) and Ithavoll (a former colony of Marduk) have managed to recover from the barbarism which engulfed the Old Federation.

Notes:

* As real-world events unfolded (in particular the toppling of the Iraqi monarchy and execution of the grandson of the Sharifian Caliph), the Terro-human Future History diverged from actual history in approximately 15 AE (1958 CE) — after the publication of Uller Uprising (1952), "Omnilingual" (1957), "The Edge of the Knife" (1957), "The Keeper" (1957), "Graveyard of Dreams" (1958) and "Ministry of Disturbance" (1958).
