Battlestar Galactica Timeline: every major event from Kobol to the arrival on Earth

The Reimagined Series chronology in order, from the exodus from Kobol and the death of the first Earth to the Fall of the Twelve Colonies and the fleet's arrival 150,000 years ago. A shorter section at the end covers the separate 1978 series and Galactica 1980.

Cylon Civil War

The Cylon Civil War was the genocidal conflict that split the Humanoid Cylons into two factions over the treatment of their Raiders and Centurions. It shattered Cylon society and drove one faction into an uneasy alliance with the surviving humans.

Ellen Tigh

Ellen Tigh was the wife of Colonel Saul Tigh, a scientist of the original Earth, and the eldest of the Final Five Cylons. She led the work that rediscovered Resurrection and created the humanoid Cylon models, and was the only one of the Five to fully regain her memories.

Elosha

Elosha was a Colonial priest who swore in Laura Roslin as President during the Fall and became her spiritual guide as the Fleet sought Earth. She read Roslin's visions against the prophecies of Pythia, and even after her death on Kobol she returned to Roslin in vision.

Every Cylon Model in Order, by Number: One to Eight and the Final Five

All twelve humanoid Cylon models from the reimagined Battlestar Galactica, in order by number, from Cavil and Leoben to Saul Tigh and Tory Foster. Who each one was, the copies that mattered, what they wanted and how their story ended.

Gaius Baltar

Dr. Gaius Baltar was a celebrated computer scientist whose vanity and manipulation by a Cylon agent handed the enemy the keys to the Colonial defenses, enabling the near-extermination of humanity. He survived to become Vice President, President, prophet, and finally a reluctant penitent.

Karl Agathon

Karl "Helo" Agathon was a Colonial Fleet officer who, stranded on Caprica after the Fall of the Twelve Colonies, fell in love with a Number Eight Cylon he later married. He became the only successful father of a human-Cylon hybrid child, Hera.

Natalie Faust: the Six who led the Cylon rebellion and died on Galactica

Natalie Faust was the Number Six copy who led the rebel Cylon faction demanding the search for the Final Five. She freed the Centurions to break Cavil's majority, allied with the Colonials against the Resurrection Hub, and was shot dead in a Galactica corridor by Sharon Agathon.

Number Six

Number Six was a humanoid Cylon model created by the Final Five after the Cylon War. Tall and typically blonde, the Sixes were noted infiltrators who blended into Colonial society before the Fall, and later split from the other models to help spark the Cylon Civil War.

Number Three

Number Three, known by the alias D'Anna Biers, was a humanoid Cylon model marked by a forbidden curiosity about the Final Five. That defiance led to the entire line being boxed, and the last surviving Three chose to die on the ruins of Earth.

Rebel Basestar

The Rebel Basestar was a Cylon basestar that allied with the Colonial Fleet during the Cylon Civil War. Sole survivor of an ambush by the rival faction, it fought alongside humanity at the Battle of the Hub and joined the Fleet in its search for Earth.
