When Has A President Been Denied His Party's Nomination?

This question is from Michael Stubbs of Cincinnati, Ohio:

When was the last time, if ever, that a sitting president was not nominated by his party for a second term?

It only happened once to an elected president. That was Franklin Pierce, the 14th president, who was elected as a Democrat in 1852. His pro-Southern sentiments and his policy of failing to lead on the divisive issue of slavery badly hurt his standing with the voters. Especially damaging was his support for the pro-slavery Kansas-Nebraska Act of 1854, which backfired on him as Kansas was overrun by pro-slavery forces, mostly from the slave state of Missouri. The events angered Northerners everywhere and helped lead to the creation of the Republican Party. When Democratic delegates gathered in Cincinnati for their convention in 1856, it was clear that they had had enough of Pierce. James Buchanan, who had been defeated by Pierce for the nomination four years earlier, won the nomination on the 17th ballot.
