The Commonwealth spanned three galaxies and a myriad of cultures. Dylan Hunt, captain of the starship Andromeda, betrayed by his allies, was frozen in time and awoke three centuries later to find the Commonweath had fallen. To fight back the chaos among the stars, Hunt must use the Andromeda to restore the Commonwealth and bring unity to the galaxy once again. He recruits a mercenary, Tyr Anasazi, and the crew of the Eureka Maru: Captain Beka Valentine, Engineer Seamus Harper, Physicist Rev Bem, and Medical Officer Trance Gemini.  After discovering the Spirit of the Abyss and its powerful weapon, the Magog Worldship, the need for the Commonwealth is greater than ever. 50 member worlds are finally recruited, and the reconstruction of the Commonwealth is finally truly underway. More and more worlds sign on, contributing their fleets to protect each other.  In the third season, Dylan and the crew travel from world to world as instructed by the Triumvirate, the leaders of the Commonwealth. But everything is building to the moment from one of his crew will betray him.  The fourth year deals with the corruption of the Commonwealth after the recent betrayal. Things become more intense as the Andromeda is expelled from the Commonwealth, Trance reveals her true form, Harper holds a weapon capable of destroying the Commonwealth, Beka becomes possessed by the Spirit of the Abyss, and a new crew member joins.

In the pilot episode, Kevin Sorbo is described as a "Greek God", a reference to his earlier role as the star of the TV series "Hercules: The Legendary Journeys" (1995).

The show's premise was pieced together from various notes that Gene Roddenberry had written in 1976

The name Dylan Hunt was also used for the lead character of two other Roddenberry TV pilots, Genesis II (1973) (TV) and Planet Earth (1974) (TV).

The name Dylan Hunt was also used for the lead character of another Roddenberry pilot, Planet Earth (1974) (TV).

Tyr Anasazi's last name is the name of a Southwestern Native American tribe that mysteriously disappeared a long time ago.

Dylan's serial number (which he recited when captured in "Forced Perspective") is H.E. 5095C21922.

Before receiving their parts on Andromeda, Lexa Doig and Lisa Ryder filmed the movie Jason X. In that film, Lexa is a human and Lisa is a robot, while on Andromeda, the opposite is true.

The basic premise of Andromeda - man from an earlier era piecing civilization back together - was the subject of three earlier Roddenberry pilots: "Genesis II" starring Alex Cord, and "Planet Earth" and "Strange New World" starring John Saxon.

Andromeda's full designation is Shining Path to Truth and Knowledge AI model GRA 112, serial number XMC-10-182. To keep it short, though, she is called Rommie.

Many Nieschieans share their first names with historical or mythological figures. Tyr is the Norse God of Warfare. Tyr Anasazi's parents are Victoria (after the British Queen) and Barbarossa (after the German emperor of the Holy Roman Empire, Frederic Barbarossa). Charlemagne Bolivar, leader of the Sabra-Jaguar Pride, takes his names from the French Emperor Charlemagne and Simón Bolívar, the South American freedom fighter.

In the episode "Answers Given to Questions Never Asked" Harper has the line, "I particularly don't want to talk about the lovable, absentee, not-so-young-and-restless Nietzschean you-know-who." Keith Hamilton Cobb played Tyr, the Nietzschean, left "Andromeda" to play Damon Porter on _"The Young and the Restless" (1973)_ in 2003.

Shamus Zelazny Harper takes his middle name from Roger Zelazny, a science fiction author.

As of the fifth season premiere "The Weight Part I", Kevin Sorbo (Captain Dylan Hunt) is the only actor to appear in every episode of the series.

In addition to the other historic/mythological Nietzchean names, Telemachus Rhade takes his first name from the son of Odysseus. Telemachus becomes a prominent character near the end of "The Odyssey".

Factual error: In "The Sum of Its Parts", Rommie says the mythological Andromeda was a Phoenician princess; she was actually Ethiopian.

The long night has come. The Systems Commonwealth, the greatest civilization in history, has fallen. Now one ship, one crew, have vowed to drive back the night and rekindle the light of civilization. On the starship Andromeda... hope lives again.
