Earth Alliance

The Earth Alliance was a political entity, centred on Earth, dominant in galactic politics between at least the 36th and 42nd centuries. It was a more loose alliance of Human colonies than the Earth Empire that preceded it. (AUDIO: The Sirens of Time, Invasion of the Daleks)

In 3562 the Earth Alliance defeated the Knights of Velyshaa. (AUDIO: The Sirens of Time)

Carthedia was recorded as a member of the Earth Alliance but during the Eleventh Doctor's visit it was found to be more closely affiliated with the Dalek Foundation. (PROSE: The Dalek Generation)

The Earth Alliance also fought a war against the Eminence. (AUDIO: Destroy the Infinite)

It was the dominant Human political entity at the time of the Dalek invasion of Vega VI and, subsequently, Mutter's Spiral itself in 4162. (AUDIO: Invasion of the Daleks)

It was at least partly concurrent with the Second Great and Bountiful Human Empire, which had spread throughout three galaxies by the 42nd century (TV: Planet of the Ood), as well as the Galactic Federation that the Earth was also a member of. (PROSE: Legacy, TV: The Curse of Peladon)
