During the American Civil war, US President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, as a followed up to his preliminary warning to any state that refused to end its rebellion against the Union. The Emancipation proclamation declared "that all persons held as slaves" within the rebellious states "are, and henceforward shall be free.". This serves as the greater moral purpose of the American civil war by the North, along with the aim of preserving the Union.
Hence, the geater moral purpose President Lincoln define for the north in the American civil war, is to END SLAVERY
Adams joined John Hancock, Paul Revere and James Otis in secret meetings to form the radical group the Sons of Liberty to oppose the taxation without representation. Violent protests in Boston targeted the homes of British authorities, making it nearly impossible for the British to enforce the Stamp Act.
