Southern Victory

Order 191 is never found by Union troops during the Maryland Campaign and therefore Antietam never occurs, instead the Army of Northern Virginia under Robert E.

As a result, the Confederacy wins the War of Secession in 1862 with official recognition from Britain and France. It operates as an independent nation from 1862 until 1944.

Atlantis

A trilogy which describes a world where the American eastern coast from the tip of Florida to Nova Scotia breaks away from the mainland around 85 million years ago and has an island biota similar to New Zealand's. It was discovered in 1452 by a Breton fisherman named François Kersauzon and named Atlantis. This seventh continent becomes a focal point in a gradually diverging timeline. Two short stories, "Audubon in Atlantis" and "The Scarlet Band", have been set in this milieu.

• Opening Atlantis (2007)
• The United States of Atlantis (2008)
• Liberating Atlantis (2009)

State of Jefferson Stories

Published in short order between May and June 2016, these stories are light alternate history tales set in a world where sasquatches and some related cryptids are real. However, unlike common popular depictions of such creatures as less evolved primates, here, they are essentially human beings, and have been integrated into society.

Moreover, in 1919, several counties in Northern California and Southern Oregon seceded, forming the new U.S State of Jefferson. This is the relevant Point of Divergence, as the discovery of cryptids did not affect the broader strokes of world history. Even after 1919, history does not differ appreciably from real history; the lives of a few historical individuals seem to be the only things altered in this timeline.

• "Visitor from the East"
• "Peace is Better"
• "Typecasting" (published on-line)

Standalone books

• Agent of Byzantium (1987): Imperial Byzantine special agent Basil Argyros is sent on various missions in a world where Muhammad became a Christian saint and consequently Islam never existed and the Byzantine Empire never fell.
• A Different Flesh (1988): A related set of short stories spanning the 17th to 20th centuries set in a universe where the ancestors of the Native Americans never crossed into the New World, only Homo erectus, who become known as "sims" to the colonists of English descent.

A U.S. mission and a Soviet mission are sent to explore the planet; these two missions back rival primitive groups in a tribal war.

• Ruled Britannia (2002) alternate history: The Spanish Armada conquers England and forces Shakespeare to write a play about Philip II. At the same time, he is secretly writing a play for the English underground resistance about Boudica's rebellion, with Boudica meant to be analogous to the imprisoned Elizabeth I.
• In the Presence of Mine Enemies (2003) alternate history: Follows the struggles of a family of secret Jews in Berlin, nearly 70 years after a Nazi victory in World War II. The events in the story follow a common theme of Turtledove's work, transplanting one set of historical events into another setting (the most prominent example being Southern Victory Series moving European history onto the American continent). In this case, the decline of the Soviet Union in the 1990s is translated to the Third Reich in the 21st century (and the secret Jews' way of life is reminiscent of Marranos in Spain).
• Conan of Venarium (2003): An authorized prequel to Robert E. Howard's tales of Conan the Barbarian.

• Fort Pillow (2006): Historical retelling of the Battle of Fort Pillow.
• "Under Saint Peter's" (2007): Short story found in The Secret History of Vampires (Edited by Darrell Schweitzer) and We Install and Other Stories. This is Turtledove's rare concession to the secret history genre, which he professes to have little interest in writing. In 2005, viewpoint character Pope Benedict XVI (unnamed but recognizable) is led by an eccentric priest to a secret bunker under the Vatican for a little-known initiation undertaken by each new pontiff since the days of Saint Peter.
• The Man with the Iron Heart (2008): Reinhard Heydrich survives an assassination attempt in Czechoslovakia by partisans and later goes on to lead an insurgent movement against the Allied occupation of Germany. Turtledove mixes information gleaned from authentic German documents and intentions with another historical transplant, in this case the Iraqi insurgency of 2003 transplanted to mid-1940s Germany.
• After the Downfall (2008): A Wehrmacht officer is transported into a fantasy world during the Fall of Berlin at the end of World War II. The story resembles the formula of Edgar Rice Burroughs and L. Sprague de Camp, mixed with Turtledove's usual allegorism as the central character sees parallels between the politics and notions of his new world and those of the world he just left.
• Reincarnations (2009): A limited edition hardcover containing eight stories, including six never before reprinted and one original story.
• Give Me Back My Legions! (2009): A historical novel detailing the events leading up to the Battle of the Teutoburg Forest, as well as the battle itself.
• Joe Steele (2015): Expanded from the short story of the same name, this alternative history deals with Joseph Stalin (whose Americanized name is the title character) having been born and raised in America. When the life of New York Governor Franklin D. Roosevelt is ended by a fire at the New York State Executive Mansion, the Democratic Party has little choice but to nominate the upcoming Steele as their candidate for the 1932 Presidential election. The novel mirrors Stalin's real world acts with actions taken by Steele through the depression, the lead up to World War II, and the ensuing Cold War through the eyes of President with the soul of a tyrant.
• The House of Daniel (2016). Historical fantasy: during the Great Depression, a young "Okie" joins the roving church-sponsored baseball team of the title.
