The First Order, or simply “the Order,” is a political and military faction that came into existence as a result of the fall of the Galactic Empire. In the aftermath of the Battle of Jakku, the Empire formally surrendered to the New Republic by signing the Galactic Concordance, a peace treaty that marked the end of the Galactic Civil War in 5 ABY. In spite of the Empire’s collapse, its legacy survived in the Unknown Regions of the galaxy, where former members of the Imperial Military plotted their return to power. Their cause was supported by some Imperial sympathizers who briefly inhabited a wing of Republic politics before abandoning the nascent democracy to join the Imperial-based movement in the Unknown Regions. Inspired by the ideals of the Empire, this movement sought to improve upon that regime by avoiding its weaknesses and flaws, ultimately resulting in the formation of the First Order.
In the decades that followed the Empire’s defeat, the First Order gradually built its strength through the secret mobilization of new fleets and armies in violation of the Galactic Concordance and Republic law.
