Earth Alliance Civil War (Babylon 5)

The Earth Alliance Civil War is an armed conflict in the Babylon 5 series, in which President Clark dissolves the Earth senate and orders martial law throughout the Earth Alliance worlds.

The armed conflict began when Mars refused to accede to President Clark's order of martial law. In retaliation, Clark ordered EarthForce to attack various installations on Mars including those containing civilians. In response to the bombings, the colonies Orion 7 and Proxima 3 and the space station, Babylon 5 seceded from the Earth Alliance. In response to B5's independence declaration, Clark ordered the destroyers Agrippa and Roanoke to seize control of the station. However, Babylon 5 with assistance from other rebel ships and Minbari warcruisers are able to repel the initial attack as well as a second wave of Earth warships.

After the second Shadow War ended, Sheridan turned his attention to overthrowing President Clark. Sheridan first liberated Proxima 3 from a group of Omega class destroyers with the use of Minbari built White Stars. In order to destroy any support Sheridan had, Clark began to spread propaganda that Sheridan was under alien influence. Sheridan eventually made it to Earth, but only with rebel EarthForce ships to avoid any connotations of alien influence only to find that Clark had turned Earth's global orbiting defense grid on the planet and then committed suicide. Earth ships along with alien vessels that were on the sidelines destroyed the defense platforms before any damage was done to the planet.
