So, basically, what if after the English civil war their was no restoration of the monarchy? What would have been the effect of a permanent Anglo-Scottish republic, and what could cause it? Maybe Cromwell chooses a better successor, or power never consolidates in his (or any other single politicians) hands and remains with a more pluralistic body. I imagine that the fact that the "republic" still amounted to one man rule made it much easier to swallow a returning king.
What would be the effect on the American colonies?
