Why did George Washington feel compelled to give advice to the nation when he left his role as president?

George Washington’s farewell address was written nearing the end of his second term (1796). During this time, the countries in Atlantic are conflicted in wars. It was also during this time that Great Britain and Revolutionary France are trying to get United States to their respective sides. His cabinet was split into opposing parties, and so he warned against foreign influence in elections, especially from Europe.
