Explanation:

Initially, the founding members of the Constitution did not support a two party system and made no provisions for it during the drafting of the Constitution. It was only during the 1790s that provisions for political parties emerged in US.Disagreements and debates on how the government would be governed led to the creation the Federalist and the Anti-Federalist groups in the Parliament.Alexander Hamilton emerged as the leader of the Federalist while Thomas Jefferson became the leader of the Anti-Federalist.
