The North and South of what would become the United States were unified through the Declaration of Independence in 1776, which asserted the colonies' independence from British rule. However, the formal establishment of the United States as a unified nation occurred with the ratification of the U.S. Constitution in 1788. This document provided a framework for governance that integrated the northern and southern states into a single federal system, officially creating the United States as we know it today.
