The Emancipation Proclamation was issued by Abraham Lincoln, the President of the United States, at the time of American Civil War. The primary objective of the Proclamation was to mark the end of slavery. It provided a well-defined legal framework for the liberation of approximately 4 million slaves in the Confederate States
The Emancipation Proclamation of January 1, 1863, gave another strategic sense to the Civil War. By issuing the document, Abraham Lincoln converted the conflict from being a clash over states´and federal powers, to one about the end of slavery.
The purpose of laws that followed the September 11 attacks were to keep the United States safe from terrorism and allow law enforcement to identify acts of terrorism before they happened.
