The Neo-Confederatism is a far-right political movement in the United States which advocates for the positive remembrance of, and, in many instances, the restoration of, the Confederate States of America. Neo-Confederatism had its roots in the "Lost Cause of the Confederacy" historical movement, which, from 1890 to 1930, sought to change the narrative of the American Civil War to de-emphasize the role of slavery in the war, portray the war as one for states' rights, to portray the Confederates as exemplars of lost chivalry, and claim that the Union Army won through brute force rather than through superior military skill. The movement became a political one as well, typically advocating for limited government, states' rights, the right of states to secede, and Southern nationalism. Groups such as the League of the South advocated for "the independence of the Southern people" from the United States, as well as promoting a Christian and Anglo-Celtic identity. Most Neo-Confederates support economic liberalism with less taxation and opposed to a fiat currency, but the neo-Confederate movement was divided between supporting laissez-faire economics or distributionism, and a minority even supported socialism.
Starting in the 1960s, the reactionary Southern Democrats began to drift into the Republican Party in reaction to the national Democratic Party's support for the Civil Rights movement, leading to the rise of neo-Confederate ideals within the GOP leadership and electorate. Starting in the 2010s, the display of the Confederate States Army battle flag at government buildings such as state legislatures and courthouses, the presence of monuments to Confederate generals and politicians in public areas, the perpetuation of the "Lost Cause" historiography in popular culture, and the commemoration of Confederate leaders by their military base, college, and school namesakes was challenged by the progressive movement, culminating in the George Floyd protests of 2020-2021 and a widespread cultural shift away from neo-Confederatism and the "Lost Cause".
As part of the backlash against this wave of progressivism, the neo-Confederate movement was involved in the unsuccessful 2021 United States coup d'etat attempt in Washington DC, during which Confederate flags were displayed within the grounds of the Capitol building before the insurrectionists were forced out.
