Interplanetary War

The Interplanetary War, also known as War of the Worlds, the Solar System War, or simply, The War was a multiglobal war that lasted from 2161 to 2251. It involved the vast majority of the Mercury, Venus, Earth, Mars, the Belt, and Jupiter's countries forming two opposing military alliances: the Rebellion and the Earth Defense Force.

As the aggressors, the Rebellion struck first, attempting to capture the Moon. Since the Outer Space Treaty insists on no weapon manufacture in space, most of the weapons had to be small enough to be smuggled in. Thus, most of the attacks in this early phase involved hit-and-run tactics.

Once Earth got wind of the attacks, they realized that the declarations of independence were not hoaxes, and organized to send massive fleets to the opposing countries in the System. This led to massive blockades and several bombing campaigns. However, since several of the wealthier nations still offered support to the EDF, they were spared from bombardment, preventing the use of nuclear weapons. Meanwhile, the rebelling nations had been preparing for this for decades, building massive tunnel networks underground, stockpiling resources and firing back upon the blockade. They were reinforced by the same wealthier nations that supplied the EDF.

Eventually, this forced planetary occupation, where the EDF occupied the neutral states and invaded their enemies from the ground. Unfortunately for Earth, this led to a long, drawn out conflict where their forces were not prepared for the environment and lacked the will to fight for years on end. Most of the invaders were pushed back, allowing the rebels to regroup after their victories.

However, during the celebrations, spies from throughout the System reported that Earth was attempting to build a new fleet that would be unstoppable. Thus, the final campaign was the Invasion of Earth. The campaign here looked much like that on several of the planets
