What was the "Era of Good Feelings?"
The "Era of Good Feelings" is generally said to have come in with the election of James Monroe in 1816. It is said to have lasted for about as long as he was president. It is called this because it is said to have been (though this is not strictly accurate) a time when there were no partisan differences in American politics. This was a time when the Federalist Party had died in the wake of the War of 1812. It was before the Whigs had split off from the Democratic Party and even before the Adams-Jackson election of 1824 had caused hard feelings between parts of the Democratic Party. Therefore, it is seen as a time when American politics was relatively calm and free of conflict.
