The Lost Cause is a historical narrative that arose in the post-Civil War South, portraying the Confederacy's fight as noble and just while downplaying the role of slavery as a central issue of the Civil War. This ideology seeks to romanticize the Confederacy and its leaders, presenting them as heroic figures defending their homeland against overwhelming odds. It also emphasizes themes of Southern honor and valor, shaping the collective memory of the Civil War and its aftermath in the Southern United States.
