Final answer:
George Washington's Farewell Address warned against the divisiveness of political party infighting, the need for national unity, and avoiding permanent foreign alliances.
Step-by-step explanation:
In his Farewell Address, George Washington warned the nation about several important issues that could affect its future stability and prosperity. A key warning he issued was against political party infighting. He alerted the country to the dangers and 'mischiefs' of political parties and their potential to divide the nation. Although Washington touched on many subjects, his emphasis on national unity and avoiding entanglement in permanent foreign alliances also stood out as pivotal points in his address.
Regarding foreign affairs, Washington's goal was friendly trade relations without favoritism or political alliances, which could entangle the United States in European conflicts. His advice was aimed at preserving the young nation's independence and preventing it from being drawn into the permanent alliances and 'imperial war and drama' of Europe. Lastly, by deciding not to seek reelection, Washington aimed to set a precedent for the regular rotation of public officials and quiet criticism that the Federalists sought a monarchy.
