What were the original two-party system in the us

The Federalist Party and the Anti-Federalist Party.

Explanation:

These were the two first parties or political organizations of republican America.

The Anti-Federalists were a movement (rather than a party) that opposed strong powers for the federal government. Their posture was motivated by fears of abuses of power by a strong central authority in detriment to society and the states. They opposed the US Constitution and exerted much pressure for the approval of the Bill of Rights.

The Federalists were America's first political party. They were partisans of a strong central government. They dominated American politics between 1789 to 1801. They wanted a central government that would promote economic growth and cultivate ties with Great Britain.
