Brethren of the Coast
The Caribbean buccaneers called themselves by this name in the 1640-1680 period. During this time, they actually formed a sort of fraternity, and did not (usually) fight each other or even steal from each other. After 1680, a new generation of pirates appeared, who did not trust each other...
