Answer:
John Adams and his friend Thomas Jefferson had very different views of how America should be like. Adams wanted a strong central government with a focus on manufacturing and joined the Federalist Party, while Jefferson was on the Democratic-Republican end and wanted an agrarian republic.
Of course, their differences also translated into international conflicts. Jefferson was fully supportive of the French Revolution and was displeased with President Washington's policy of neutrality. Adams, on the other hand, favored Great Britain in this conflict and attempted to maintain the USA out of this military struggle.
