William Henry Harrison occupied the least amount of time as a United States’ president, only serving 31 days as president. President Harrison’s presidency began March 4, 1841 and ceased on April 4, 1841.

This term additionally served to make him the first U.S. President to pass away while still in office and as a result of his untimely demise prompted changes in the methods of presidential succession employed in the United States.

How Long Was The Shortest Term?

William Henry Harrison’s term lasted only 31 days, as he developed a severe illness soon after becoming president. 

Following a long and cold inaugural, he contracted a severe cold that quickly progressed into pneumonia. Within days, his condition deteriorated to the point where he died 31 days after becoming president on April 4, 1841.

 He was the first U.S. president to die while serving in office.

How did this Impact U.S. History?

The death of William Henry Harrison had a significant impact on the direction of American history as it concerned presidential succession. Before his death, there were no clearly defined guidelines for presidential succession in the United States Constitution if a president died while in office.  

When Harrison died, and John Tyler became president, this was an important milestone in how the office of vice president operated for succeeding presidents.

 As a result of this incident, vice presidents were established as successors to the presidency, not just "acting presidents." 

This was eventually codified as part of the Twenty-Fifth Amendment to the Constitution, thus providing a mechanism by which future administrations would continue to operate in the United States.

Conclusion

William Henry Harrison is the shortest serving U.S. president in history, holding this record with Lewis Cass (who served 31 days) as no. 2 for shortest streak of uninterrupted executive power during the current presidency (January 20th to February 19th 1849). Although it was only an initial term of 31 days, his presidency was instrumental in establishing a precedent for presidential succession within the United States based on established Constitutional practices.
