Good question Scott ,
I know that some tribes are very much better off than others , I guess to some extent it was luck if a tribe ended up on lands with resources , if it had been known before hand the mineral rights would probably have been aquired by the land owning classes . Many tribes were moved off their traditional lands for this reason and their does exist a sense of injustice and inequality over that.
Dublin, Irelands capitol city was established by Vikings along the banks of the river Liffey, their long boats with a shallow draught could easliy make it up the great rivers , right into the belly . The landmarks of this period of time were round towers , usually built around monasteries , in the event of a raid the most valuable items were taken up into the tower for safe keeping . Subsequent to the Vikings we had about 800 years of British rule here , this year is the centenary of the foundation of the Irish state . Certain areas of the country ,due to geography were difficult or impossible for the Brits to police or control . There remains of a large swamp/delta west of Cork city , its innundated with water now due to the contstruction of two dams on the river Lee , in the bad old days of empire British soldiers and RIC(Royal Irish Constabulary) men knew if they ventured into the delta they'd probably never see the light of day again . Its no surprise the rebel spirit is still strong in that area . At best the Brits could hope to keep a lid on trouble in the cities or garrison towns , local knowledge of the more mountainous terrain and wooded regions meant they never got a hold . In a handfull of these wild places the Irish language (Gaelige) still remains the everyday mother tongue . Many attempts by the crown to 'plant' Ireland with its own citizens failed ,the province of Ulster being the exception .
So anyway Im still glad I started this topic ,I know Ive plenty to learn about the world .
