Lincoln's House Divided Speech

The House Divided Speech was an address given by senatorial candidate and future president of the United States Abraham Lincoln, on June 16, 1858, at what was then the Illinois State Capitol in Springfield, after he had accepted the Illinois Republican Party's nomination as candidate for US senator. The nomination of Lincoln was the final item of business at the convention, which then broke for dinner, meeting again at 8 pm.
