Final answer:
The War of 1812 did not end with the Treaty of Tecumseh but with the Treaty of Ghent. This treaty was to restore borders and properties to their status before the war and included unfulfilled promises to return land to Native Americans.
Step-by-step explanation:
The statement that the War of 1812 ended with the Treaty of Tecumseh is false. The correct treaty that officially ended the War of 1812 is the Treaty of Ghent, which was signed on December 24, 1814. This treaty restored territories and properties to their pre-war owners and returned all borders to their 1811 state. It also included a provision for the Indians to have their lands as of 1811 returned, although this agreement was not honored.
The death of Tecumseh in 1813 at the Battle of the Thames was a significant blow to Native American resistance during the war. After the war, the Federalist Party suffered a decline, and the focus of American policy shifted towards expansion, often at the expense of Native Americans.
