In OTL, the period of time in American history known as the Era of Good Feelings was only 8 years long, lasting from 1816, right after the end of the War of 1812, to 1824, where the party broke up from intraparty conflicts.

Now, the challenge is to create the longest "Era of Good Feelings" in the United States.
