Abraham Lincoln makes a speech at Cooper Union in the city of New York that plays an important role in his election to the Presidency.

Abraham Lincoln was the 16th president of the United States, serving from 1861 until his assassination in 1865. He led the United States through the American Civil War, defeating the Confederate States of America and playing a major role in the abolition of slavery.

The Cooper Union speech or address, known at the time as the Cooper Institute speech, was delivered by Abraham Lincoln on February 27, 1860, at Cooper Union, in New York City. Lincoln was not yet the Republican nominee for the presidency, as the convention was scheduled for May. It is considered one of his most important speeches. Some historians have argued that the speech was responsible for his victory in the presidential election later that year.

The Cooper Union for the Advancement of Science and Art, commonly known as Cooper Union, is a private college on Cooper Square in Lower Manhattan, New York City. Peter Cooper founded the institution in 1859 after learning about the government-supported École Polytechnique in France. The school was built on a radical new model of American higher education based on Cooper's belief that an education "equal to the best technology schools established" should be accessible to those who qualify, independent of their race, religion, sex, wealth or social status, and should be "open and free to all".
