@Flick @GalacticTurtle Edward I conquered Wales and there are still many castles remaining which were built around this time, although many early medieval castles were damaged during the civil war.
The Stuart dynasty were the next in line after Elizabeth I, the last Tudor monarch, died without an heir. James I of England (James VI of Scotland) was a direct descendant of Elizabeth's grandfather Henry VII. The Stuarts had a turbulent time with issues over religion, parliament, civil war, lines of succession, foreign wars etc, but ended with the Act of Union which joined Scotland to England and Wales.
We've had an interesting history so far, and I suspect we're living through another very interesting chapter.
