The office of the US president was established in 1789, and in the 231 years since the first man was elected to the highest office in the country, 44 have people have held the title. US Presidents are only allowed to sit for a maximum of two, four year terms, but although any gender can hold the position, every president so far has been a man. Of the 44 who have held office, only ten presidents have failed to win re-election for a second term, when they have attempted to.
