The document summarizes the development of political parties during the Federalist Era in the United States. It explains that Alexander Hamilton and Thomas Jefferson disagreed on economic and foreign policy issues, as well as the degree of power held by the federal government. These disagreements led to the formation of the first two political parties - the Federalists led by Hamilton and the Republicans led by Jefferson. The election of 1796 was the first in which presidential candidates openly identified with political parties, with John Adams elected as the Federalist candidate and Thomas Jefferson becoming Vice President as the Republican candidate.
