Lincoln Delivers Cooper Union Speech in New York
As the Republican presidential nomination race intensified ahead of the 1860 election, Abraham Lincoln traveled east from Illinois to address concerns among moderate Republicans about his viability. On February 27, 1860, he spoke at Cooper Union in New York City to an audience of influential political and business leaders, delivering a carefully researched argument against the expansion of slavery into the territories. Lincoln distinguished his position from more radical abolitionists while firmly opposing popular sovereignty on the issue, earning widespread praise and media coverage. The speech helped solidify his standing in the East and contributed directly to his nomination later that year.
