Great War: American Front

Great War: American Front is set in Turtledove's Timeline-191, an alternate history where the Confederate States won the Civil War and remain an independent nation. The novel depicts World War I being fought on American soil, with the United States allied with Imperial Germany against the Confederate States and their allies including Britain and France.

Timeline-191 is Harry Turtledove's extensive alternate-history universe that diverges from real history when the Confederacy wins the Civil War with the help of British and French intervention. Great War: American Front, published in 1998, is the first book in the Great War trilogy within this larger series.

The novel follows multiple viewpoint characters on both sides of the conflict, including soldiers, civilians, and political figures from the United States and the Confederate States. Turtledove uses this multi-perspective structure to depict the war across different fronts and social classes, a technique he employs throughout the Timeline-191 series.

The novel is set in the 1910s, paralleling the timeframe of World War I in real history. The North American conflict erupts when the European great-power alliance system draws the US and CSA into opposing camps, mirroring the chain of alliances that triggered the real First World War.
