We know quite a lot about the past from looking at the things it has left
lying around; and the most detailed knowledge we have of the past comes from
what people of the time wrote down. When they wrote it with intent to give a
future reader a clear account – albeit usually with at least some bias
– of what happened, we call it history; when they wrote it for other
reasons (such as accounts to keep trade honest or to help an owner keep track of
what he owns), one could argue that our interpretation of it is more
archeological than historical, but we usually treat the reading of such records
as history anyway (they are, if nothing else, more apt to be honest). As a
result, the scope of history is limited to the era of written records – to
which this page is devoted. For events prior to the invention of writing, see
my time-line.
I measure time backwards from the present (nominally 2001 –
see below for why) and all of history falls within the range
of times ago that I'd naturally represent in kilo-years, a.k.a. millennia
– writing emerged within the last ten millennia and anything more recent
than a century (tenth of a millennium), while genuinely history, shades into
current affairs and the mythology of present political realities, so I chose to
leave it to others. If you want information on closer time-scales than the last
century, seek elsewhere: and please be sensible enough to bear in mind that any
author, whose writings you can hope to read, is close enough to the
socio-political realities of the events discussed that you should engage your
best talent for skepticism (especially if what they say agrees with
your prejudices) in assessing the veracity of their accounts of the recent
past.
One such elsewhere that may have a sobering impact on readers
is Piero
Scaruffi's list of wars
and casualties, steadilly expanding outwards from the 20th century as he
gathers more information. As Eric Bogle
says at the end
of No
Man's Land
(lyrics –
PDF), even since
the war to end
wars, it has all happened again and again and again and again and
again.
My main aim here is merely to record the time-line of our past, in which the
order of events takes centre stage, even when the events in question are
unrelated – proper histories generally (and properly) tell a cogent story
of related events, ignoring unrelated events elsewhere; but, here, I want to
provide the framework for seeing how those disparate stories' time-lines match
up. As a result, although this page treats the last ten
millennia because what we know of them is predominantly from written
records, I include here the things we know from other sources.
51 yr ago: carbon dating's The Present
In
contrast to my choice of 2001 as the present, there is a well-established
precedent of using 1950 as The Present for purposes of dates before
the present, a.k.a. BP. The reason for this is that this is when humanity's
rash experiments with nuclear weapons so tainted the world with radioactive mess
as to render carbon (and other isotopic decay methods of) dating after that date
unreliable. Stuff deep enough in the ground at that date to not be tainted can
still be dated, as long as it's not been chemically interacting with things
living since then.

Great Britain (hence also its colonies) waited until
1752 to make the transition to the Gregorian calendar. September 1st was
followed by September 13th. The same year, Great Britain also changed from
March 25th as the start of the year to January 1st (although the tax

April 1st, which looks suspiciously like a hold-over from this).

Introduction of the Gregorian calendar (named after

In 1507 a Scottish

1.689 k yr ago: conversion of Constantine
The official date, 312
AD, at which the Roman Empire switched from oppressing christianity to promoting
it. The oppression had actually been limited: there was official persecution in
249 AD under Decius and 303–304 AD under Diocletian, probably with other
outbursts of varying officialness, but generally the Roman Empire protected all
religious minorities from the general population's antipathy. The general
population resented the christians because they didn't honour the gods,
so all the bad things that happened were clearly their fault, the gods'
punishment on the general population for tolerating the atheists in their
midst (much as some who now call themselves christians now blame bad
things on certain of their fellow citizens).

2 ky ago: start of the common era
This is the
nominal date of Christ's birth: but it's fairly clear that – even for
those who accept the historical reality of the man in question – the late
Roman and dark age tracking of dates, combined with poor back-tracking through
the centuries in which years were referred to relative to the reigns of assorted
rulers, introduced something like four years of inaccuracy. (For example, the
biblical account of a bright star moving about the sky can fairly sanely be
matched to Chinese records of a comet if we accept a four year discrepancy,
while the claim that he was born in Herod's reign implies he was born in 4BCE or
earlier.) The Christian system of year numbering refers to years since this
nominal start-point as anno domini or AD; somehow, the world
has been persuaded to use the same numbering but described as CE (for Common
Era) instead of AD, despite religious and calendrical differences. The year
before 1 CE (a.k.a. 1 AD or 754 AUC) is thus the first year
before the common era, 1 BCE (a.k.a. 1 BC, the first year before Christ; I've
heard that, technically, that's supposed to be before his circumcision, on the
8th day of his life, putting his birth on December 25th 1 BC – although
I've also heard that, before his official birthday was set thus, the early
church didn't care much about when he was born but placed it in spring); earlier
years are correspondingly numbered backwards, so the n-th year BCE is (in the
numbering I'm using here) 2000+n years ago – I chose 2001 CE as my nominal
reference date to make that arithmetic easy ! Note that there is no year
zero in the CE/BCE or AD/BC system.
2.045 k yr ago (45 BC, 709 AUC)
Introduction of the Julian
calendar. The Romans had previously used a luni-solar calendar in which the
insertion of leap months was determined by elected priests; consequently, the
decisions had been more political than scientific, leaving the calendar 80 days
behind the Sun in 46 BC. Caesar hired an Egyptian astronomer, Sosigenes, to
sort out a better calendar, based on the Egyptian solar calendar. 46 BC was
extended to get back in sync with The Sun – it was later known as The
Year of Confusion – and the start of the year was shifted from March
15th (the Ides of March) to January 1st. (Thus 80 days were inserted but 74 of
those days were counted as falling in the following year.) The conspirators who
murdered him on the Ides of March the next year, 44 BC, thus did so on the
former New Year's Day; I cannot help but suspect that contained some
symbolism.
49 BCE, January 10th, Julius Caesar paused on the banks of
the Rubicon, a river formally marking the border between Italy and Gaul, the
province to which he'd been sent with his army. Roman law forbade him to bring
his army out of his province: he had to return to Rome and present himself to
the senate's judgement of how he'd fared in his campaign; but he knew political
machinations were afoot by his enemies. If he took his army with him, he broke
the law; if he didn't, he was defenceless against ruthless opponents. While he
mulled this dilemma (according to his later account), some of his soldiers
crossed the river to enjoy music being played by a shepherd on the other side;
Caesar took this as his cue to take his army to Rome, thereby starting a civil
war pivotal to the Roman republic's later tranformation into an empire.

2.287 to 2.212 k yr ago: Archimedes
The nearest the Romans got to
making a
decisive contribution to mathematics was killing Archimedes on the beach at
Syracuse in 212 BCE. Archimedes, aside from his prolific contributions to
mathematics and physics, invented several machines of war which helped Syracuse
keep the Romans at bay for some years. He was born around 287 BCE and narrowed
the value of a famous constant to 223/71 < π < 22/7.
2.332 k yr ago: Alexandria
Alexander the Great established
Alexandria as his capital for Egypt, in 332 BCE as part of his campaign of
conquests. There may well have
been an earlier settlment dating back to as much as 3 k yr ago. His general
Ptolemy subsequently converted Alexandria into a centre of intellectual
excellence. Euclid (born c. 325 BCE) was one of the first luminaries to
flourish there.

Rome
founded: April 21, 753 BCE according to tradition; archeological evidence

historical records used the AUC dating system – Anno Urbis
Conditae – which counts years from the founding, but not until long
enough after the event that their traditional reckoning (as now extrapolated
back from comparing with other sources using other dating systems) was out of
sync with what archeology now claims.
