On March 29, 1790, John Tyler was born in Virginia. He later became the 10th president of the United States. Tyler assumed the presidency after the death of William Henry Harrison, raising important questions about presidential succession. He asserted that he was fully president, not just “acting,” setting a precedent followed thereafter. Tyler’s term included conflicts with his own party and debates over annexation of Texas. His unusual political path and succession role make him a notable figure in presidential history.
