He Had a Role in the Founding of America
Connor may not have known how important his role was, but he became a key figure in the American Revolution, and by extension the founding of the United States of America. This was of course a key event that changed the course of the very world. Connor seeks training from the Master Assassin Achilles Davenport, after his mother is killed and village burned by forces he believes to be the Templars.
His quest is one of revenge but in the process he meets many key figures of the time like Benjamin Franklin and William Johnson. He also bears witness to events like the Boston Massacre, Boston Tea Party, and the signing of the Declaration of Independence.
Of course one of the Assassin’s most important associates was none other than George Washington, the first president of the U.S. During his quest to hunt the Templars, Connor ends up helping the Patriot movement, and even saving Washington’s life. He eventually finds out it was Washington’s forces that burned his village, but continues using the Patriots to his advantage. You can in part say that in the Assassin’s Creed Universe there would be no America without Connor.
