What was a major consequence of the signing of the Declaration of Independence?

The signing of the Declaration of Independence marked a significant moment in history, as it formally declared the thirteen American colonies' intent to separate from British rule. This document articulated the colonies' grievances against King George III and emphasized the ideals of individual rights and self-governance. As a direct consequence of declaring independence, the colonies mobilized to engage in armed conflict with Britain, leading to the Revolutionary War. This war was fought to secure the autonomy and rights promised by the Declaration, making it a pivotal catalyst for not only independence but also for the eventual establishment of the United States as a sovereign nation.

The other options do not accurately reflect the immediate consequences of the Declaration. The Civil War emerged decades later due to different issues, such as slavery and states' rights. The Bill of Rights was introduced later to protect individual liberties in the newly formed government and was not a direct result of the Declaration. Additionally, the notion of the nation being divided into two parts pertains to events that occurred well after the Revolutionary War, particularly in the context of sectional conflicts leading to the Civil War. Thus, the connection between the Declaration of Independence and the Revolutionary War is clear and fundamental to understanding the historical context surrounding these events.
