How did political parties originate in the united states and what are three major differences between the federalists and democratic republicans?

Federalists agree to the constitution and believe that a strong central government is needed for the preservation of the union. They focused and criticized the flaws of Articles of Confederation and view their rivals as having no solutions. The leaders in this government are strong and well organized. Anti-Federalists on the other hand, agree to the weak federal government and fully supported the bill of rights; they further argued that the constitution being proposed by the federalists contain no protection of the rights of the individual. They are skeptical on the constitution as it is being influenced by the colonialism.

The answer would be hard press.
