The Passamaquoddy Bay Islands Dispute: A Forgotten Border Issue of the War of 1812
The Passamaquoddy Bay Islands Dispute was a territorial disagreement between the United States and Great Britain over islands in Passamaquoddy Bay, resolved under Article IV of the Treaty of Ghent in 1817. The decision awarded Moose, Dudley, and Frederick Islands to the United States and all other islands, including Grand Manan, to Great Britain. Though often overlooked, it exemplifies how the War of 1812’s peace treaty addressed long-standing boundary questions.
