Earth Alliance The Earth Alliance was a political entity , centred on Earth , that was formed by the 22nd century and became the dominant form of human government in the Mutter ' s Spiral between at least the 36th and 42nd centuries . It was a more loose alliance of human colonies against common threats than the earlier and more politically integrated Earth Empire .

( AUDIO : " Invasion of the Daleks " ) The remnants of the Earth Alliance allied themselves with the parallel universe Alliance Daleks , as they came to be known , which declared war on the enemy Daleks and fought alongside the Earth Alliance . Within approximately six years , they had driven them back to a small stronghold within the Sol system . Over time , Kalendorf , Alby Brook and Mirana began to develop doubts about the Mentor and the Alliance Daleks . Reports suggested that they enforced peace and order with the same ruthlessness with which the Daleks from the primary universe subjugate and conquer . Several planets which refused to provide troops to the war effort were reduced to a medieval level , having had their whole industrial infrastructure destroyed . In a more extreme example , Emeron , which had been embroiled in a nuclear war by the time that the Dalek War began , was reduced to a Stone Age level . These worlds came to be known as the Punished Planets . The actions of the Alliance Daleks led Kalendorf to conclude that they had merely swapped one dictatorship for another , outwardly more benign one , and that humanity should fight against these Daleks as well as their more outwardly evil counterparts .
