The unanimous Declaration of the thirteen united States of America, July 4th, 1776:

When in the Course of human events it becomes necessary for
one people to dissolve the political bands which have connected
them with another and to assume among the powers of the earth,
the separate and equal station to which the Laws of Nature and
of Nature's God entitle them, a decent respect to the opinions of
mankind requires that they should declare the causes which
impel them to the separation.

We hold these truths to be self-evident, that all men are created
equal, that they are endowed by their Creator with certain unalienable
Rights, that among these are Life, Liberty and the pursuit of Happiness. —
That to secure these rights, Governments are instituted among
Men, deriving their just powers from the consent of the governed, —
That whenever any Form of Government becomes destructive of
these ends, it is the Right of the People to alter or to
abolish it, and to institute new Government, laying its
foundation on such principles and organizing its powers
in such form, as to them shall seem most likely to effect
their Safety and Happiness. Prudence, indeed, will dictate
that Governments long established should not be changed
for light and transient causes; and accordingly all experience
hath shown that mankind are more disposed to suffer, while
evils are sufferable than to right themselves by abolishing
the forms to which they are accustomed. But when a long
train of abuses and usurpation, pursuing invariably the
same Object evinces a design to reduce them under absolute
Despotism, it is their right, it is their duty, to throw off such
Government, and to provide new Guards for their future security.
