Alexander Hamilton established economic policies including a national bank and tariffs to encourage manufacturing, which led to the emergence of sectional differences between the North and South. This sparked the formation of the first political parties - the Federalists supported Hamilton's vision while the Democratic-Republicans opposed a strong federal government and championed states' rights. Tensions increased as America was drawn into international conflicts during the French Revolutionary Wars, leading to crises both foreign and domestic during Washington and Adams' administrations. The election of 1800 marked the first peaceful transfer of power between opposing political parties as Jefferson defeated Adams in a close election.
