Ah Terry: James the sixth took the Crown from Edinburgh to London. One reason for this was that London was and remains a far more robust market centre and therefor a more appropriate setting for the head of state. Another sociological reason, lost to many, is that Edinburgh stunk. Literally! Was absolutely filthy. Raw sewage was thrown from the windows to the shouts of "Gardez Lou" (Edinburgh French) and festered there until the rains washed it down the gutters. It was not fit for a king.
And so, "To the Victor goes the spoils" we took over in London. Scotland won! No matter how many bards have written of the day that Scotland would finally succeed, it is an undeniable fact that we did and we buggered it up.
I think I explained it best when I wrote "A Parcel of Rogues".
