The Terran Federation, sometimes simply called The Federation, is the primary stellar government featured in the British Blake's 7 science-fiction television series of the late 1970s. It is portrayed as a ruthless, quasi-fascist, totalitarian state.
How the Federation came to power was never clearly stated in the series, though in the episode "Countdown" it was mentioned that it was formed some 200 years before the main rebel attack on "Control" (see below). The Federation primarily expanded its territory though conquest, enslaving weaker worlds and exploiting their resources to fuel the military. In other cases, the Federation would infiltrate more distant worlds where they would help a local tyrant achieve power or install a malleable ruler (episodes "Bounty" and "Horizon"). These puppet leaders would rule over their own planets, but under the constant shadow of the main Federation and their planets would eventually become part of the Federation. How far the Federation's power spread was never clearly indicated either, as mentioned in the series there were many "neutral worlds" in existence.
The Federation maintained control of its citizens through fear and through dosing the air and water with pacification drugs (episode "The Way Back"). In extreme cases such as Roj Blake's, brainwashing and re-programming were used. In at least one case, a planet was equipped with a radiation bomb that would wipe out the inhabitants in the case of rebellion (episode "Countdown"). In the episode "Horizon", the Kommissar indicated that the incident of rebellion was less than one in 100,000 and that many of these were snuffed out in youth. Despite all these efforts, or perhaps because of them, the Federation was never able to quite stamp out resistance.
The Federation's main seat of power is located on Earth, the capital world where most inhabitants serve with drug-induced loyalty. The Federation was commanded by the President of the High Council, below which was the Supreme Commander, who was in control of the military and Space Command. At the beginning of the series, Servalan held the position of Supreme Commander. Later, when Star One began to break down, she staged a coup and took over as President (in the episode "Star One"). She initially ruled alone, without a High Council or a Supreme Commander. The High Council was later restored (in the episode "Rumours of Death"); the office of Supreme Commander was offered to a Space Commander if he captured the Liberator, in the episode "Volcano", but this attempt failed.
