On Tuesday, Nov. 19, at 6:30 p.m., the Trumbull Library welcomes the return of David Koch, assistant professor of History at Housatonic Community College; Nov. 19, 2013 marks the 150th anniversary of the address.

The Civil War began as a Constitutional conflict, but ended as a crusade to abolish the institution of slavery. This talk will explore the role of a transformation in the thinking of President Abraham Lincoln, and how this led to the transformation of the entire war and, as a result, the history of the United States.

Drop in. Doors open at 6:15 p.m. For more information visit trumbullct-library.org, or call 203-452-5197.
