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."

A 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

Piper's note on Atomic Era dating: "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."
