The Declaration of Independence says it was necessary for the colonies to alter their former systems of government and declare independence because Great Britain had subjected them to tyranny and abuses that left them no choice but to dissolve political ties. It states that "necessity constrains them to alter their former Systems of Government" due to the oppressive actions of the British Crown, which compelled them to seek freedom and independence
. The Declaration emphasizes that the colonies must declare the causes that impel them to separation to justify their right to revolution and independence from Britain
. Specifically, the Declaration asserts that the colonies are "absolved from all allegiance to the British Crown" and "ought to be totally dissolved" from political connection with Great Britain, so they can exercise the full powers of independent states, such as levying war, concluding peace, and establishing commerce
. In summary, the Declaration says it was necessary to break away because of the tyranny and abuses by Britain, which forced the colonies to seek independence to secure their unalienable rights to life, liberty, and the pursuit of happiness
