What was the only thing holding Europe together during the middle ages?

Both groups strongly opposed slavery.  They were not as successful as South Carolinians who used slave labor.

The Highland Scots are unique in the way they moved in large, organized groups directly from their homeland to the North Carolina colony. The Highlands is a beautiful but rugged land of mountainous, rocky terrain and harsh winters. In the 1700s it was a poor region where the staple foods were oatmeal and beef.

The Scottish clans were originally extended networks of families who had loyalties to a particular chief, but the word 'clan' is derived from the Gaelic 'clann', meaning literally children. In Scotland, a clan is still a legally recognized group with an official clan chief.
