US President Abraham Lincoln, who successfully campaigned for the abolition of slavery (13th Amendment to the United States Constitution) is assassinated by a sympathizer of the Confederacy.
One year later, US Congress passes the Civil Rights Act of 1866, the first US federal law to define US citizenship and affirm that all citizens are equally protected by the law – excluding Native Americans.
Lincoln (2012) is Spielberg’s cinematic monument for the President’s achievement. Spielberg’s other films dealing with slavery in the US are: The Color Purple (1985) and Amistad (1997). He has never directed a Western or a film about Native Americans.
