High Quality Content by WIKIPEDIA articles! The Earth Alliance is the name of a fictional alliance of the nations of Earth and off-world colonies in the television series Babylon 5. The transition of Earth government from a democratic, elected government to an authoritarian, militaristic one and back to a democracy again is a major theme of the series. It is considered one of the five major galactic diplomatic/military powers (Earth Alliance, Narn Regime, Minbari Federation, Centauri Republic and the Vorlon Empire) in the Babylon 5 pilot episode movie "The Gathering". They have separate seats at the head of the council chambers on the Babylon 5 station. The League of Non-Aligned Worlds sit in the general assembly section. The Vorlons departed from the galaxy along with the Shadows and the last few remaining First Ones leaving the galaxy to the younger races.
