Order 191 is never found by Union troops during the Maryland Campaign and so the Battle of Antietam never occurs. Instead, the Army of Northern Virginia, under Robert E. Lee, marches into Pennsylvania, crushes George B. McClellan's Army of the Potomac at Camp Hill, and proceeds to capture the city of Philadelphia. As a result, the Confederacy wins the War of Secession in 1862 with official recognition as an independent nation from Britain and France. Another popular moniker for the series is Timeline-191.

• Bombs Away (2015)
• Fallout (2016)
• Armistice (2017)

First published in May 2016, the stories are set in a world in which Sasquatch, Yeti, Indonesian Hobbits, merfolk, and other cryptids are real or not extinct. Unlike common popular depictions of such creatures as less evolved primates, they are integrated into a world designed for ordinary humans ("little people"). Like other ethnic minorities cryptids experience cultural assimilation and racial stereotyping, become less familiar with ancestral customs and languages, and interbreed with the majority.

In 1919 several counties in northern California and southern Oregon seceded, forming the State of Jefferson. Neither the new state nor the earlier discovery of cryptids greatly affected United States or world history, with events such as the Chinese invasion of Tibet, 1973 oil crisis, and Iranian hostage crisis still occurring. Most American Sasquatch live in the state; although they are still a small minority, size is a protected class in Jefferson, with anti-discrimination law guaranteeing reasonable accommodation.

Most stories depict Governor Bill Williamson, Jefferson's second Sasquatch leader, who during the late 1970s and early 1980s meets Charles Kuralt, Jerry Turner, Nobuo Fujita and a Yeti Dalai Lama. From the state capital of Yreka he promotes his small, rural, and obscure state to the nation and world as an example of how different species can peacefully cooperate.

• A Different Flesh (1988): A related set of short stories spanning the 17th to 20th centuries set in a universe in which the ancestors of the Native Americans never crossed into the New World, and only Homo erectus, who become known as "sims" to the colonists of English descent, did so. Suggested by Turtledove's reading of Stephen Jay Gould, the novel's main theme is what effect the proximity of a closely-related but significantly-different species would have on how humans view themselves, one another, and the great chain of life.
• Noninterference (1988): A human interstellar survey team violates a directive to avoid interference with alien civilizations, with disastrous long-term consequences. Republished in the collection 3xT.

A U.S. mission and a Soviet mission are sent to explore the planet; both 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 by 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 that of Marranos in Spain.
• Conan of Venarium (2003): An authorized prequel to Robert E. Howard's tales of Conan the Barbarian depicts a 14-year-old Conan's resistance to the imperialist legions who occupy his village.
• Every Inch a King (ISFiC Press) (2005): An acrobat becomes king of a small country.

• "Under Saint Peter's" (2007): Short story found in The Secret History of Vampires (Edited by Darrell Schweitzer) and We Install and Other Stories.

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 that is 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, which in this case is the Iraqi insurgency of 2003 being 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.

When the life of New York State 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 its 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 a 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.

• A Massachusetts Yankee in King Arthur’s Court (1992): John F. Kennedy is briefly transported back in time to ancient Britain, where he meets up King Arthur of Camelot. The story is collected in Mike Resnick's 1992 alternate history anthology Alternate Kennedys.
• Uncle Alf (2002, now readable on line): A novella included in the collections Alternate Generals II and Atlantis and Other Places. The German Empire has won World War I when Alfred von Schlieffen lived to see his Schlieffen Plan executed successfully and Germany occupies France and Belgium.

The story is told from the perspective of US President and Canadian Prime Minister Harris Moffatt III, and parallels the treatment of indigenous peoples of the Americas. The title is a reference to the city of Vilcabamba, Peru, the site of the last Inca resistance to Spanish colonization.[18]
