What ideas are expressed in the Declaration of Independence to explain the reasons for the fight

against Britain?

The main ideas of Declaration of Independence include the notion that "all men are created equal" and that everyone has the right to "life, liberty, and the pursuit of happiness." The Declaration of Independence says that the purpose of government is to protect these rights and values.

Explanation:

Britain, the mother country, did not give the colonists these rights. The lack of freedom gave the colonists an "incentive" to fight Britain and have their own rights.
