That great American hero, editor, school teacher, and Presbyterian clergyman Elijah Lovejoy left the pulpit and returned to the press in order to be sure his words reached more people. The Civil War might have been averted and a peaceful emancipation of slaves achieved had there been more like him. After observing one lynching, Lovejoy was committed forever to fighting uncompromisingly the awful sin of slavery. Mob action was brought against him time after time; neither this nor many threats and attempts on his life deterred him. Repeated destruction of his presses did not stop him. "If by compromise is meant that I should cease from my duty, I cannot. I fear God more than I fear man. Crush me if you will, but I shall die at my post..." And he did, four days later, at the hands of another mob. Not one of the ruffians was prosecuted, indicted or punished in any way for his murder. On the contrary, some of Lovejoy's defenders were prosecuted! One of the mob assassins was later elected mayor of Alton!

So where's justice? Was his blood ever avenged? There was one young man around who heard of these events which took place 80 miles from his home. He gave a speech referencing needless mob violence. He didn't refer to Lovejoy specifically, he didn't need to, everyone knew what he was talking about, when he said:

Accounts of outrages committed by mobs form the every-day news of the times. They have pervaded the country from New England to Louisiana; [these stories of mobs] are neither peculiar to the eternal snows of the former nor the burning suns of the latter; they are not the creature of climate, neither are they confined to the slave-holding or the non-slave-holding states. Alike they [or, these mobs] spring up among the pleasure-hunting masters of Southern slaves, and the order-loving citizens of the land of steady habits. Whatever, then, their cause may be, it is common to the whole country.

So the Speaker chose to address mob rule in broader, national, context. To warn that living our lives by the whims of mobs is a recipe for national disaster. This speech was given to a local chapter of the American Lyceum Movement (which was a public education movement) in Springfield, Illinois in 1838. The speaker was 28-years-old at the time. His name was Abraham Lincoln

Lincoln was deeply moved by Lovejoy's martyrdom. And carried the memory of it, as a horrible illustration of the outcome of mob rule, into his presidency and into the emancipation of slavery that his presidency affected.

Note: the brackets in the Lincoln quote are added to help the listeners understand what the proper antecedent is.

A Source: Some of the information for this illustration gleaned from http://abelincolnhistory.com/speeches/lyceum-address.htm. There's other tidbits as well from this site that would be helpful, such as, Lincoln felt that all laws should be obeyed, even the laws of slavery, until such time that they could be changed; otherwise, societies descend into governance by mob rule.
