John Tyler [SEP] Start in Virginia politics
In 1811, at age 21, Tyler was elected to represent Charles City County in the House of Delegates. He served five successive one-year terms and sat on the Courts and Justice committee. The young politician's defining positions were on display by the end of his first term in 1816—strong, staunch support of states' rights and opposition to a national bank. He joined fellow legislator Benjamin W. Leigh in supporting the censure of U.S. senators William Branch Giles and Richard Brent of Virginia who had, against the Virginia legislature's instructions, voted for the recharter of the First Bank of the United States.
