Question

why did political parties emerge in the new republic

Answer 1

Well, the best answer is to look at what the purpose of political parties is, namely, to elect candidates and bring like-minded people together. Political parties are best at organizing followers to win elections and therefore pass policy initiatives that are popular with that particular party. 

Answer 2

Two Parties Emerge. The election of 1796 was the first election in American history where political candidates at the local, state, and national level began to run for office as members of organized political parties that held strongly opposed political principles.
