Gallente Federation
Type: EVE Online Profile Background
Market price: ~0.43 USD
The Gallente Federation is one of the largest star empires ever to be seen in the New Eden cluster, surpassed in volume only by the vast realms of the Amarr Empire. Yet even though its many regions are patrolled by a large and powerful navy, the Federation is governed by the consent of its peoples. Remarkably, the Gallente and their partners in the Federation founded and expanded their empire according to the principles of democracy. Additionally, the Federation has done much to enhance the standard of life of all the peoples living within its borders, including migrants and exiles from other empires. The Federation might seem to be the one pure beacon of freedom and justice in New Eden. Yet its history is not without dark episodes. Gallente Ultra-Nationalism seized power during the turbulent period leading up to the Caldari-Gallente War and contributed significantly to the embittering nature of that conflict. The Gallente government has sometimes displayed authoritarian tendencies, suppressing independence movements and exiling dissidents. Federation foreign policy is viewed with a jaded eye even by their Minmatar allies. Amarr and Caldari opinions on Gallente interventionism are rarely expressed in terms suitable for polite company. The vastness of the Federation includes poverty, criminality and outright depravity in its sweep. In the end though, it is a free society where success is conceivable for every citizen.
