On July 12, 1804, Alexander Hamilton, former U.S. Secretary of Treasury, died after a duel of honor with Aaron Burr, Jr. (the son of a President of the College of New Jersey), the sitting Vice-President of the United States. These were two notables, one of whom was reckoned among the Founding Fathers of the United States of America.
Eliphalet Nott (1773-1866) preached a sermon occasioned by the death of Alexander Hamilton that is widely credited with bringing disrepute to the traditional practice of duelling to avenge one's honor.
It is true that the last duel in the United States officially took place in 1859. But it is also true that the sermons of Nott, and Lyman Beecher, two highly respected Presbyterian ministers, significantly eroded support for the practice of duelling.
Take a look at these sermons, as well as the articles written by Thomas Smyth (Works, Vol. 7), and consider how American Presbyterians opposed the practice, and how it came to an ignominious end.
