The Declaration Of Independence was signed in Philadelphia in 1776.
The actual process of the signing of the Declaration of Independence began on 2 August. The first of the signatories was John Hancock, the President of the Congress, who signed, in bold, below the text and in the centre of the Declaration. Other delegates, starting with those from the northernmost state-New Hampshire-and continuing unto the southermost state-Georgia-then began to sign.
