What was one of the reasons for writing the Declaration of Independence?

The Declaration of Independence was fundamentally a response to the grievances and violations faced by the American colonists under British rule. One of the primary motivations for writing this document was to articulate and justify the colonists' claim that King George III had infringed upon their natural rights, including life, liberty, and the pursuit of happiness. The Declaration goes into detail, listing specific actions taken by the King that were viewed as oppressive and unjust, serving as both an assertion of their rights and a plea for independence. This articulation of grievances was essential not only to inspire unity among the colonists but also to gain support from other nations in their fight for autonomy.

The other options do not capture the main intent of the Declaration. While the creation of a new government was indeed a result of declaring independence, it was not the primary reason for the Declaration itself. Proving the need for military support was important in the context of the Revolutionary War, but it was secondary to establishing the moral and philosophical grounds for independence. Lastly, while trade agreements were important for the newly forming nation, the Declaration's main focus was on the assertion of rights and grievances against the British monarchy.
