what is a natural way of evolving civilizations?

at some point there are only tribes

as they gain resources and knowledge they connect with more tribes

spliting the work, organizing, some taking care for food others blacksmithing,medicine,inventing,

…and administrative(laws and people putting those laws in effect)

now they are kingdoms-still abiding by same RULES set

multiple kingdoms or variants of those around the globe

kingdoms trade in GOODS, on how much of what you need and your trader needs

if someone wont trade you there is a neighbour somewhere

SOME kingdoms fall into WRONG hands

wars are started

SOME kingdoms expand, increasing their resources

because of their dominance (in resources) over others its not possible to trade in goods

but they NEED goods to survive

others, natural, kingdoms are self-sufficient at all points or trade in goods-optimal

they have to convince others to agree to some arbitrary value of "coins" is worth some goods

in the start they set coin value to high(making their goods worth less) but they dont care as they have plenty

to invite as much kingdoms to trade as they DESPERATELY NEED goods

once they get many kingdoms to trade with them in coins they can freely manipulate

cant manipulate coin value of goods but can invent other things

other kingdoms between themself still trade in goods

invent a new sword and set price of it freely

force many "new things" amongst kingdoms

kingdoms forced to trade "new things" between themself in coins not goods

flood the market with "new things" and good trading is gone

now they have resource dominance and coin value managment

they can freely manipulate coin value

as their kingdom was and is evolving their laws must also be evolving/adding to make their people believe

believe coin trading is a greater good and not manipulative

believe so they wouldnt rebel against them

they have resource dominance, including people that come with them
