On April 4, 1841, President
William Henry Harrison died 31 days after his inauguration, the shortest presidential term in American history. Up until this point, the question of what happened when the president died was entirely theoretical.
Article II, Section I of the Constitution of the United States, was vague on the matter: Whether the vice president was to become a full-fledged president, or simply act as president while retaining the office of vice president, was completely open to interpretation. When informed of President Harrison's death,
John Tyler concluded that the section's wording made him president without any qualifiers. Accordingly, Tyler returned to
Washington, D.C. and immediately had himself sworn in as president. Meanwhile, Harrison's
Cabinet, led by
Secretary of State Daniel Webster, had already convened within an hour of his death and had elected to recognize Tyler as vice president acting as president, not president. Furthermore, they decided that all major presidential decisions would be made by majority vote of the Cabinet, greatly diminishing Tyler's power. They informed Tyler about this arrangement during their first cabinet meeting. He then held a second inauguration before the Cabinet to bolster his claim before immediately moving into the White House, which was still black with mourning drapes for Harrison's death. This was a controversial series of maneuvers that earned Tyler considerable criticism from many
Democrats and some
Whigs, including the derisive nickname "His Accidency". Even so, Tyler adhered to his position, refusing to open mail that addressed him as anything other than president. Nominally a Whig, Tyler's liberal use of the veto power and his general opposition to Whig policies alienated him over the course of his term, and Tyler was soon formally expelled from the Whig Party. He eventually sought election to a full term under the
Tyler Party (named after himself) and dropped out of the race. Despite his controversies, Tyler was successful in legitimizing his position as president, and both houses of
Congress voted to recognize him as such. ==Constitutionality and legacy==
