Read the excerpt from the Declaration of Independence.

"Nor have we been wanting in attention to our British
brethren. We have warned them from time to time of
attempts by their legislature to extend an unwarrantable
jurisdiction over us. We have reminded them of the
circumstances of our emigration and settlement here.
We have appealed to their native justice and
magnanimity, and we have conjured them by the ties of
our common kindred to disavow these usurpations,
which would inevitably interrupt our connections and
correspondence. They too have been deaf to the voice
of justice and of consanguinity."
