Mobile Suit Gundam Wing

About the story

Humanity's expansion into space marks the beginning of the A.C. (After Colony) calendar. A century after the first space colony, L1, is completed, the United Earth government rules the colonies through military oppression. In A.C. 165, space inhabitants begin resisting Earth's sphere, with the unarmed, nonviolent Heero Yuy acting as mediator. He delivers speeches in the colonies and on Earth to spread his ideals, but is assassinated in A.C. 175. One account says the killer belonged to the special-service organization that preceded OZ. The colonies then fall into chaos and are suppressed by the special forces that later become OZ. On Earth, the pacifist Sanc Kingdom and its royal Peacecraft family are also destroyed. In A.C. 195, colonists fiercely opposed to the United Earth government's domination send five Gundams to Earth, launching “Operation Meteor” to annihilate the special-service force OZ.
