In the first month of the war alone, half of the total human population perished. 0079, Side 3, the furthest colonies from Earth, declared themselves the Principality of Zeon and began a war of independence against the Earth Federation.
Hundreds of gigantic space colonies now float around Earth. Over fifty years have passed since the beginning of the Universal Century - in which humanity began colonizing outer space to solve the problem of overpopulation. A boy named Amuro Ray finds himself caught up in the conflict when he becomes the unwilling pilot of the Federation’s new mobile suit - the Gundam. However, when Zeon learns about the Federation’s new mobile suits being developed at the Side 7 space colony, Char Aznable launches an attack to destroy them.
In the year 0079 of the Universal Century, the war between the Earth Federation and the Principality of Zeon has reached a stalemate.
