I'd score you an 80% on that answer, CYP.
The James Monroe Administration (1817-1825) was referred to as the "Era of Good Feeling" because the Federalist Party had died out and 99.99% of the Country was Democratic-Republican.
When Monroe was re-elected President in 1820--he would have won a Unanionous Vote in the Electoral College--except for one Elector (I believe in New Hampshire) voted against him because he felt ONLY George Washington should have the honor of unamious election.
The Era of Good Feeling ended as quickly as it began when the conservative wing of the Democractic-Republican party "splinterd off" and formed the National Republican Party.
The National Republican Candidate, John Quincy Adams, was elected President in 1824 and the two-party system re-emerged.
