Context

They operated as privateers (legal pirates with Letters of Marque), blurring the line between state-sanctioned warfare and piracy. Their raids weakened Spanish treasure fleets, funded English colonization, and forged a maritime legend that still defines the "Golden Age of Piracy" imagination.

The Spanish called them piratas or luteranos (Lutherans/heretics). To the English, they were patriotic heroes expanding the realm.
