Rival trading empires could still cooperate

Portuguese, Dutch, and British possessions often appeared in the same commercially valuable regions. That overlap produced warfare, but it also encouraged practical cooperation between rival trading systems. Merchants and states could share access when doing so preserved the profitable movement of goods. The comparison of Portuguese and Dutch map points makes that coexistence visible rather than treating every imperial boundary as an impermeable wall. Pragmatism therefore mattered alongside rivalry in early modern maritime empire.
