#38: John Tyler (1841-1845)
Ascending to the presidency following the death of his predecessor, John Tyler stood out as a fervent proponent of states’ rights. His tenure was marked by his unprecedented transition from vice president to president, showcasing his dedication to the principles of decentralized governance.

As the first vice president to succeed to the presidency due to a president’s death, Tyler faced challenges in asserting his legitimacy. His opposition to key elements of his own party’s agenda, particularly regarding economic policies such as the re-establishment of the National Bank, led to his expulsion from the Whig Party.
