After the Japanese bombed Pearl Harbor
Answer: The Federalists and the Anti-Federalists were the name of the two political parties that evolved. The main leader of the Federalist party was John Adams and the main leader of the anti-federalist party was George Washington. The issues that motivated the Federalist party were their belief in a strong central government, ratifying the Constitution, and they wanted industrialization and a national bank with government aid to build roads and canals. The anti-federalists instead of wanting a strong central government wanted a strong state government, they favored farming over manufacture and no national bank to help build roads and canals.
