Which group opposed slavery, were fierce fighters, and settled the town of Darien?

The group that opposed slavery, were fierce fighters, and settled the town of Darien were the Highland Scots.

Explanation:

Highlanders are descendants of Celts. Initially settled mostly in northern mainland and islands of Scotland, the Highland Scots moved to the New World, more specifically to the North Carolina colony, in large and organized groups. They were famous for being fierce fighters and for being against slavery. They settled the town of Darien but, after a battle against the Spanish, a number of them left the settlement.
