Although the Founding Fathers of the United States did not originally intend for American politics to be partisan, early political controversies in the 1790s over the extent of federal government powers saw the emergence of two proto-political parties- the Federalist Party and the Democratic-Republican Party, which were championed by Framers Alexander Hamilton and James Madison, respectively. However, a consensus reached on these issues ended party politics in 1816 for a decade, a period commonly known as the Era of Good Feelings.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who were the leaders of the Federalist and Democratic-Republican parties?
Framers Alexander Hamilton and James Madison
