The Pilgrims settled territory that the Spaniards claimed was part of the Viceroyalty of New Spain, so that must make them “illegal aliens.”
England TOOK the territory a bit later ~ doing so as the strongest power available to rule Virginia, and besides, King James had already been assigned Acadia by Filippe ~ they knew each other well ~ and New France had been assigned to France, but with an indeterminant boundary between Acadia and New France. I think that happened when Argall, then Governor of Virginia, picked up the Surveyors in a rowboat, in distress, out in the Bay of Fundy and took them back to Jamestown. They'd apparently been surveying the boundary between the former Portuguese colony and New France.
There are a number of other border anomalies that popped up in the East where you'd think the Spanish and other Europeans would have had a good grasp of things and not made those mistakes, but out West, up in what is now Saskatchewan, the Spanish had surveyors marking a line from Minnesota to West Central Saskatchewan (meeting 54 degrees 40 minutes) to make sure Spanish territory in the otherwise totally unexplored West was not mistaken for French land (otherwise identified as the watershed draining into Hudson's Bay).
It's interesting that officially Spain didn't know about the entry to the inside passage but in marking this point they definitely gave away a few state secrets! Cabrillo didn't go up there for a longtime after Spain delineated New France all the way to the West Coast!
Leftys are so stupid, at that time there were no laws against it ergo, they couldn’t be illegals...
