Which president served two non-consecutive terms?

Grover Cleveland, the only President to ever serve nonconsecutive terms, was the 22nd and 24th President of the United States (1885-89) (1893-97). He was known to be honest, independent, and opposed to corruption and the spoils system.

Explanation:

One very good and possible reason (that was at the same time very logical from his perspective) why George Washington decided to call for a policy of neutrality was to avoid United States participation in European wars (2). And he did this with a good reason. A young nation as the US in those times couldn't afford making and drafting men into an army and then shipping them to Europe to help a possible ally, they needed to build their own nation at the time.
