The Nantucket series (also known as the Nantucket trilogy or the Islander trilogy) is a set of alternate history novels written by S. M. Stirling. The novels focus on the island of Nantucket which was transported back in time to 1250 BC due to something called "The Event". Shortly thereafter a conflict develops between the democratic Republic of Nantucket and a group of renegade Americans led by the ex-Coast Guard lieutenant William Walker. The series was nominated for the Sidewise Award for Alternate History in 2000.

In the three novels of the Nantucket series, a cosmic disturbance characterized by an elliptical dome of fire (called "The Event" in the series) transports the island of Nantucket and its inhabitants back in time into the Bronze Age. The world of circa 1250 BC, which corresponds to the late Heroic Age of Greek mythology, is populated by a large variety of hunting, nomadic and agricultural people, as well as well-documented Bronze Age cultures including Ancient Egypt, the Hittites, and Mycenaean Greece.
The trilogy describes the day-to-day problems of adaptation and survival and the emotional and social trauma of losing connection with the modern world. Much of the plot deals with ongoing conflicts between the different factions of the island's population. Some Nantucket residents wish to dominate the world for their own benefit, others wish to interact with local populations through trade and cultural development, while most just want to survive, work hard, and claw their way back to something approaching their pre-Event way of life.
They have the extreme good luck that, transported in time together with island, is a US Coast Guard sailing ship captained by a tough African American lesbian expert in martial arts, who provides leadership for Nantucket's armed forces. (She insists upon using the term "Coast Guard" rather than "Navy", though what she eventually builds up is a worldwide naval force).
However, also transported back with the ship is the ambitious and totally unscrupulous young lieutenant William Walker, who seizes the opportunity to form a band of renegades, flee the island to live like gods amongst the Bronze Age peoples of Europe and the Middle East. Walker—who, unfortunately, is as smart as he is callous—exploits the 'magic' of gunpowder and iron-forging to build up an empire of his own, one that will inevitably conquer and enslave the entire world.
Therefore, as the series progresses, it becomes clear to Nantucket's scaled-down Government that sitting back and reinventing isolationism is no real option, and that the people of Nantucket have no choice but build an army, a navy, and a set of foreign alliances of their own and take the fight to Walker - and in the process, build up what amounts to an empire of their own.
By the end of the third book, Nantucket is the dominant member of a sizable and expanding network of allies, rather reminiscent of the British Empire (though Britain itself is called "Alba" in the novel, one of Nantucket's protectorates and a source of "warrior tribes" to be enrolled as mercenaries in its armies), and the Nantucketars ("Eagle-People", "Islanders", "Nan-Tukh-Tar", etc.) seem well on their way to re-enacting the United States’ Manifest Destiny three thousand years early, with Native Americans succumbing to disease and becoming virtually extinct on Long Island and the Nantuckers setting out on transcontinental expeditions and reaching California by sea, as well as starting to settle what corresponds to Argentina.
Nantucket has 'Outport' colonies spanning the globe, with bases in the Caribbean, Argentina, the Azores, South Africa, Zanzibar, Madagascar, Mauritius, Bombay, etc.; basically, anywhere there is a good harbor situated close to existing or future trading routes, the Republic is on the scene. The Alban Alliance rules the British Isles where Walker initially tried to carve out a kingdom, and are a close ally, a source of labor and military recruits, and, as its people absorb more of the New Learning, look like being at the heart of a very early Industrial Revolution. Babylon, Hittite Empire and Mitanni (a vassal of Babylon), are also allies, though how long that will last now that they have arms industries of their own is anyone's guess, even with an Islander military officer married to Babylon's ambitious young king. At the end of the third book, these allies are already laying plans for carving up the Caucasus and Persia between them.
Major powers 
- Greater Achaea (Greece), which was the location of Walker's second—and much more successful—attempt at empire-building, but which is now ruled by King Odikweus (Odysseus/Ulysses of Iliad and Odyssey fame).
- Tartessos, an Iberian city-state which gained greatly from its new King's decade-long alliance with Walker's Meizon Achaea, and which managed to survive its unsuccessful challenge to Nantucket for control of the sea.
Minor powers 
- Egypt, gained some basic New Learning from one of Walker's lieutenants, a fanatical — and naïve — Afrocentrist who was shocked to discover that the "Black Egyptians" were not truly black. After Egypt's defeat at the 'Battle of Armageddon' and the loss of its Canaan territory to Babylon, this lieutenant fled to Meroe, an iron-rich region in east-central Africa, with the intention of giving the black population a leg up before armed whites started arriving in large numbers. Egypt itself still remains out of Nantucket's system of alliances, but some of Pharaoh's officers are being suborned, and an obvious strategic objective would be to dig the Suez Canal three thousand years ahead of schedule.
- Sicilian Republic was formerly an Achaean colony but is now an independent nation after it was invaded by Nantucket. The government is currently divided between the Sicilian natives, freed slaves, and Achaean colonists.
- Alba, the Bronze Age England, is an ally of Nantucket after the Islanders defeated Walker and his Sun People allies there.
- There also appears to be a threat growing out in Central Asia, where Walker's lone surviving heir - a young but highly intelligent and capable girl, a true daughter of her father - and a convoy of mostly Achaean rejectionists have chosen to carve out a new empire in the Fergana Valley region, far, far away from the reach of Islander naval power.
Significant Characters
