1841John Tyler becomes US PresidentFirst vice-presidential succession in US historyJohn Tyler was sworn in as president on 4 April 1841 after William Henry Harrison died one month into his term, becoming the first US vice president to succeed a president who died in office. Tyler's assertion that he held the full powers of the presidency, rather than acting as a caretaker, set a lasting precedent later codified in the 25th Amendment. His independent governing style quickly alienated the Whig party that had elected him.
