Death, assassination, and replacement of the former Presidents have resulted in the shortest terms served by some of the US Presidents. The president is elected through the Electoral College to serve for a four-year term and eligible for another term. The 22nd amendment of 1951 sets the limit of the presidency and prohibits anyone seeking a third full term presidency. The amendment also prohibits anyone from seeking election to the presidency more than once if the individual had previously served in the office as president or was acting for more than two years. In total, 43 persons have served 44 presidencies that spanned 56 full four-year terms. The shortest sitting president was William Henry Harrison, serving for only 31 days.
