Treaty of Ghent
The Treaty of Ghent ended the war with no major boundary changes to the north, except for some islands in Passamaquoddy Bay, an issue that was resolved after the war. To the south, the United States in 1813 occupied all of West Florida west of the Perdido River, and Britain would not support Spain in restoring its prewar colonial boundaries. With the Treaty of Ghent the British abandoned their three decades-long quest dating from 1783 to establish a British protectorate Indian buffer state on the American Northwest Territory to block the Americans from expanding westward.
