Battlestar Galactica is an American science fiction media franchise created by Glen A. Larson. The franchise began with the original television series in 1978 and was followed by a short-run sequel series (Galactica 1980), a line of book adaptations, original novels, comic books, a board game, and video games. A re-imagined version of Battlestar Galactica aired as a two-part, three-hour miniseries developed by Ronald D. Moore and David Eick in 2003. That miniseries led to a weekly television series, which aired until 2009. A prequel series, Caprica, aired in 2010.
All Battlestar Galactica productions share the premise that in a distant part of the universe, a human civilization has extended to a group of planets known as the Twelve Colonies, to which they have migrated from their ancestral homeworld of Kobol. The Twelve Colonies have been engaged in a lengthy war with a cybernetic race known as the Cylons, whose goal is the extermination of the human race. The Cylons offer peace to the humans, which proves to be a ruse. With the aid of a human named Baltar, the Cylons carry out a massive attack on the Twelve Colonies and on the Colonial Fleet of starships that protect them. These attacks devastate the Colonial Fleet, lay waste to the Colonies, and virtually destroy their populations. Scattered survivors flee into outer space aboard a ragtag array of available spaceships. Of the entire Colonial battle fleet, only the Battlestar Galactica, a gigantic battleship and spacecraft carrier, appears to have survived the Cylon attack. Under the leadership of Commander William Adama, the Galactica and the pilots of "Viper fighters" lead a fugitive fleet of survivors in search of the fabled thirteenth colony known as Earth.
