Once again, the first spoiler goes to the Ai incarnation of Gandhi.
<curse> Quite unfortunately, the notes I had taken have gone erased from a network drive...
...I still remember how it went more or less, so I wrote down a very nice story here.
But then our network crashed and I lost it.
Second attempt.
So. We had left Gandhi with 6 cities at the dawn of the Middle Ages.
The world was at peace, but that was not to last long...
A border dispute between Arabia and the south indian nation of Vijayanagar caused war to be declared.
Skirmishes were fought, with Ansars entering deeper and deeper into Vijayanagar territory, but still not managing a decisive win.
India saw a chance to put its Elephants to a test then, and joined the battles against Abu Bakr, moving the front line back to the Arab border.
Things stalled for several decades, until Persian, Chinese and Sumerian cavalries were bought to the Vijayanagar side.
The fight was soon over, with the last Arabian city conquered by Persia. It was in fact the persians and the sumerians who took the largest share of the arabian peninsula.
India had fought on the winning side of this alliance, but did not manage to gain anything from the war.
Sumer and Persia were growing to be the largest world powers, while Japan was quietly occupying its lands. In fact, a small city was founded in northern Japan by Lan Xang, and that very settlement would prove crucial in deciding India's destiny a few centuries later.
After the Arabian conflict, more wars followed. Inconclusive skirmishes were fought at the Persia-Sumer border, but the main event was a new world alliance against China, which was quickly overrun by Xerxes' armies.
India had initially taken a neutral position, but towards the end of this war Gandhi made his first political blunder, joining the doomed chinese side.
Within two or three turns, all his cities were lost to Persian and Sumerian forces, and he barely managed to save his capital in a humiliating peace deal.
India would maintain its single city for many more centuries, but Gandhi's game was over.
(I know -this should belong to the next spoiler; but you want to know the epilogue, don't you...)
In spite of Persia's large gain from the chinese war, Sumer still managed to rival Xerxes' power well to the end of the Industrial Age.
Persia were however the first to build Modern Armors, and that meant the sudden end of both Sumer and the Vijayanagar.
Gandhi, having learned his lesson, stood quiet and well-behaved in his capital.
An uneasy peace followed, with Persia busy working on their new project -a Spaceship- but always threatening.
Vijayanagar experienced Xerxes' wrath when he attacked Persia to regain control of their former capital, only to be banished to a couple of cities on the Maldive islands (now, *I* wouldn't mind that...

).
In the meantime, that little Lan Xang city on japanese land had changed owner several times, and had already been the cause of many a war between Japan and Lan Xang.
It now was one of the many Persian possession, but Tokugawa could clearly not sleep until that city returned to what he considered its legitimate owner (that is, himself). And he attacked.
Persian counterattack was slow and reluctant this time, and two attempts at invading Japan were repelled, even if at a high cost to Tokugawa.
The dispute might have ended there, but Lan Xang saw an opportunity to revive their long-standing rivalry with Japan, and allied with Persia.
Tokugawa, in return, proposed an alliance to Gandhi.
Gandhi accepted.
It was 1810 AD; two years later, persian troops took Delhi, putting an end to Indian history (conquest loss, 381 points).
The fight went on, but took an unexpected turn when Persia declared war on its former allies and conquered the ancient Laotian republic, achieving domination in the late '800.

EDIT: as I said in the other spoiler, if there is interest in looking at what the AI does in a CotM map, I'll keep this up (and maybe even try to take a few screenshots...).
Or maybe some chronicle-prone civver may volunteer to do that after or instead of submitting their game...
