The Galactic Empire Fan Club, also known as the First Order, was a group of leftover Imperials and emos organized by Snoke into a an anti-Republic terrorist organization. They want to be the Galactic Empire in every way but name, except better. Also they are known to be prejudiced against clones.
The first order took great pride in slaughtering villages of innocent people and blowing up planets because that is what evil organizations do. They used their super weapon Starkiller Base to destroy the New Republic throwing the Galaxy into another Empire VS Rebels scenario.
Disney Canon Edit
They formed in the shadows after the end of the galactic civil war. The New Republic dismissed these First Order politicians in the senate as not being a threat and accused Leia of warmongering when she wanted to investigate the organisation.
This caused Leia to leave the senate and form a paramilitary force, the Resistance. This began the Cold War.
