The United States has seen a total of 46 presidents since its founding, each leaving their unique mark on the nation’s history. Franklin D. Roosevelt holds the record for the longest presidency, serving an unprecedented four terms from 1933 to 1945. On the other end of the spectrum, William Henry Harrison‘s presidency was tragically short, lasting only 31 days in 1841 before he succumbed to pneumonia.
Looking at party affiliations, 19 presidents have been Republicans, while 15 have been Democrats. The remaining 12 belonged to other parties, including the Federalist, Whig, and Democratic-Republican parties. In terms of electoral victories, Richard Nixon‘s 1972 re-election stands out, with him winning 60.7% of the popular vote and carrying 49 states against George McGovern.
Age has also played a role in presidential history. Theodore Roosevelt was the youngest president, taking office at 42 years old after the assassination of William McKinley. In contrast, Joe Biden became the oldest president to assume office, beginning his term at 78 years old.
When it comes to ethnic backgrounds, the majority of US presidents have roots tracing back to the British Isles and Western Europe.
