to portray the Confederacy's cause as noble and most of the Confederacy's leaders as exemplars of old-fashioned chivalry, defeated by the Union armies not through superior military skill, but by overwhelming force. They believe the commonly-portrayed Civil War history to be a "false history". They also tend to condemn Reconstruction and giving the vote to African Americans. On its main website, the Sons of Confederate Veterans (SCV) speaks of "ensuring that a true history of the 1861-1865 period is preserved", claiming that "[t]he preservation of liberty and freedom was the motivating factor in the South's decision to fight the Second American Revolution." James M. McPherson has written on the origins of the United Daughters of the Confederacy (UDC), stating: "A principal motive of the UDC's founding was to counter this 'false history' which taught Southern children 'that their fathers were not only rebels but guilty of almost every crime enumerated in the Decalogue.'" Much of what the UDC called "false history" centered on the relationship between slavery and secession and the war. The chaplain of the United Confederate Veterans (UCV), forerunner of the Sons of Confederate Veterans, wrote in 1898 that history books as written could lead Southern children to "think that we fought for slavery" and would "fasten upon the South the stigma of slavery and that we fought for it ... The Southern soldier will go down in history dishonored". Referring to a 1932 call by the Sons of Confederate Veterans to restore "the purity of our history", McPherson notes that the "quest for purity remains vital today, as any historian working in the field can testify." In the 1910s, Mildred Rutherford, the historian general of the UDC, spearheaded the attack on schoolbooks that did not present the Lost Cause version of history. Rutherford assembled a "massive collection" which included "essay contests on the glory of the Ku Klux Klan and personal tributes to faithful slaves". Historian David Blight concluded: "All UDC members and leaders were not as virulently racist as Rutherford, but all, in the name of a reconciled nation, participated in an enterprise that deeply influenced the white supremacist vision of Civil war memory." Historian Alan T. Nolan refers to the Lost Cause as "a rationalization, a cover-up". After describing the devastation that was the consequence of the war for the South, Nolan states: Leaders of such a catastrophe must account for themselves. Justification is necessary.
