Star League Defense Force

The Star League Defense Force (SLDF) was the principal military force defending the Star League, a conglomeration of star systems within roughly 500 light years of Terra. The Star League Defense Force left the Inner Sphere after Stefan Amaris overthrew the ruling First Lord of the Star League, Brian Cameron. After fighting a long serious of bloody battles throughout the Star League, General Aleksandr Kerensky led 90% of the Star League Defense Force out beyond the Inner Sphere, hoping to end the internicine violence endemic to the Inner Sphere after the death of Stefan Amaris. The SLDF returned 300 years later as the Clans, a technologically superior military that invaded the Inner Sphere in 3049.
