John Tyler became the tenth President of the United States (1841-1845) when President William Henry Harrison died in April 1841. He never wavered from this conviction. He attended the College of William and Mary and studied law. Tyler soon joined the states’ rights Southerners in Congress who banded with Henry Clay, Daniel Webster, and their newly formed Whig party opposing President Jackson. In 1842 Tyler did sign a tariff bill protecting northern manufacturers. The Webster-Ashburton treaty ended a Canadian boundary dispute; in 1845 Texas was annexed. When the first southern states seceded in 1861, Tyler led a compromise movement; failing, he worked to create the Southern Confederacy.
