A common trend in european history also goes back to the Greeks.
Disunity is strenght.
sounds like a conflicting sentence does it.
The greeks were divided into dozens of polis (city states) and several alliances, all in this small area of land, that was mountanous and yet very accesable tot he sea.
This disunty lead toallot of warfare, never ending simmering conflict that doesnt lead to mass destruction appears to be the main factor among many other that leads to an open society that is open to new thoughts and is dynamic.
The never ending simmering warfare lead the greeks to develop the most effective fighting forces in the ancient world, what made it effective was the adaptability of the greeks and thier aquired discipline.
They were not isolated , so they absorbed all the technology and science from thier nieghbours and even started on the road to developing the sientific method that the Islamic civilization later invented after perfecting greek science.
When unleashed on the world they were decisive,
The persians were richer had a much larger population something like 20 to 1 in population.
They had better metal technology, thier swords and armour were better, they had better cavalry,
thay had better archers, better siege tactics..
and they had a 5 to 1 advantage in numbers but still the greeks went through them like a knife through butter..
Why were they so succefull?
the main factor is non stop war at a medium level for hundreds of years.
This is why europeans rule the world today,
they were not the most civilized, infact in some areas they were embarrasingly primitive, like personal hygiene..(taking a bath , basically washing yourself became a regular activity sometime in the late 1800 to early 1900, prior to that they didt wash..
everybody from indians to chinese to japanese, were shocked, how could someone so filthy defeat them??
europe only had peace during the early middle ages, 1200 to 1400 only 200 years.
from 50bc to 1200 there was constant war.
from 1350's till 1945 non stop war...
and the europeans had the luck of receiving mature technology in gunpoweder, canons and hand canons form the arabs.
The chinese invented gunpoweder but the arabs developed the right mixture to use, and then the chinese got this in turn from the arabs. during the southern Sung Dynasty.
The first canons appeared simultanoulsy in both the muslim world and china in the mid 1200's.
The muslims specialized in grenades(introduced to europe from Granada), incendiery weapons (basically gunpowder bomb covered in vaseline(distillied from crude oil).
The chinese took a liking to canons and they ane the koreans of the Goryoo dynasty produced the best cannons in history till the french in the 1650's modernized thier canons.
the europeans recieved all these mature technologies and ran with it.
They had better land, could support higher populations, and the non stop wars forced them to develope the best fighting skills..
So when for example the british defeat the Indians at panipat,
while outnumbered 7 to 1, and while indian muskets and canons were superior, bieng lighter, more range, less powder.
Only the Ottomans gave them a run for thier money, and maybe the japanese samurai during the sengoku.The ottomans succeeded becuase they were allways fighting the europeans, the moment the decide to relax and enjoy their conquests they fell behind.
by the time the europeans finished thier 30 year war and made the peace of westphalia.
They invented tactics that outclassed the ottomans, and this was put to practice immiedietly after the last siege of Viena.
within 30 years the ottomans suffered defeat after defeat, and it has been going on since,
To sum it up..
disunity and constant war as long as it doesnt lead to mass destruction is actually conducive to
progress and millitary strenght.
this classic science fiction short story sums it up.
