Tyler firmly believed in manifest destiny and saw the annexation of Texas as economically advantageous to the United States, signing a bill to offer Texas statehood just before leaving office and returning to his plantation.
When the American Civil War began in 1861, Tyler at first supported the Peace Conference. When it failed, he sided with the Confederacy. He presided over the opening of the Virginia Secession Convention and served as a member of the Provisional Congress of the Confederate States. Tyler subsequently won election to the Confederate House of Representatives but died before it assembled.  Some scholars have praised Tyler's political resolve, but historians have generally given his presidency a low ranking. Tyler did make progress in combining the American and British navies to stop oceanic African slave trafficking under the Webster–Ashburton Treaty. That treaty also peacefully settled the border between Maine and Canada. Today, Tyler is seldom remembered in comparison to other presidents and maintains only a limited presence in American cultural memory.[1]
