Why were many Americans disturbed by the emergence of political parties in the 1790s

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.

This was a stunning new phenomenon that shocked most of the older leaders of the Revolutionary Era. Even Madison, who was one of the earliest to see the value of political parties, believed that they would only serve as temporary coalitions for specific controversial elections. The older leaders failed to understand the dynamic new conditions that had been created by the importance of popular sovereignty — democracy — to the American Revolution. The people now understood themselves as a fundamental force in legitimating government authority. In the modern American political system, voters mainly express themselves through allegiances within a competitive party system. 1796 was the first election where this defining element of modern political life began to appear.

The two parties adopted names that reflected their most cherished values. The Federalists of 1796 attached themselves to the successful campaign in favor of the Constitution and were solid supporters of the federal administration. Although Washington denounced parties as a horrid threat to the republic, his vice president John Adams became the de facto presidential candidate of the Federalists. The party had its strongest support among those who favored Hamilton's policies. Merchants, creditors and urban artisans who built the growing commercial economy of the northeast provided its most dedicated supporters and strongest regional support.Explanation:
