U.S. Presidents in Order

All 47 presidencies and the 45 people who held them — from Washington to the present, in order.
The White House, seat of the U.S. presidency

The office George Washington accepted in 1789 had no real precedent and almost no defined powers. Everything since has been improvisation, argument, and accumulation — a job that has expanded from a part-time executive of a fragile republic into the most scrutinized position on earth. Reading the presidents in order is the fastest way to watch that change happen.

This list runs by presidential number, one through forty-seven. There are forty-seven presidencies but only forty-five people: Grover Cleveland and Donald Trump each served two non-consecutive terms, so each is counted twice in the numbering and once here. Every name links to a full account on BriefHistory; the one-line note explains why that presidency mattered.
