Was the declaration of independence intended to be a formal declaration of war why or why not

No. The war started a year before the Declaration of Independence was written.

Explanation:

The Declaration of Indepedence was not intended to be a formal declaration of war. In fact, the war had already started a year before the declaration was even written. The war had begun because of the complaints of the colonists, and their belief that the King of England did not care about them. However, as the war progressed, this feeling increased, and the colonists reached the conclusion that nothing could be done to mend the relationship between the two countries. Therefore, the declaration was written in order to explain the reasons for the war and the interests of the colonists to sever all ties with England.
