Earth Republic

The Earth Republic is a fictional government organization featured in the Defiance multimedia franchise. They first appeared in the Defiance online video game by Trion Worlds and have made numerous appearances in the Defiance television series on Syfy.

Overview
The Earth Republic, or E-Rep, is a government entity on Earth of the year 2046. Although it is an interpsecies organization, its ruling body and army is made up primarily of humans. The Earth Republic claims jurisdiction over most population centers, regardless of who the dominant species is, but some communities, such as Defiance, maintain their independence. The Earth Republic tried to wrest control of Defiance on numerous occasions, mostly so they could lay claim to the McCawley Mines, which housed a 3,000 year-old alien vessel containing an ancient weapon of mass destruction.

One of the E-Rep's representatives, Connor Lang, traveled to Defiance in order to broach negotiations with Mayor Amanda Rosewater, with whom he had history with. Connor's efforts to endear Amanda towards accepting assistance from the Earth Republic failed and he was ultimately killed by Datak Tarr.

When the Irathient Plague swept through Defiance, the Earth Republic Army set up a blockade around the town, preventing people from leaving in order to reduce the risk of the spread of contagion.

Colonel Galen Marsh of the Earth Republic Army knew that he would not be able to get a foothold in the town so long as Amanda Rosewater remained Mayor, so he secretly backed Datak Tarr in the next mayoral election, feeling that he could manipulate him into turning Defiance over to the Earth Republic. This plot succeeded and on the very day that Datak Tarr was announced as the new mayor, the Republic claimed jurisdiction over the town and the McCawley Mines.
