"If there is one art that Humanity has truly honed to absolute perfection, it is that of war."

The First Galactic War was a devastating civil war that lasted for twenty-nine years, longer than the Human-Covenant War that had ended not long before. This war, which began as a succession of uprisings among new human colonies, eventually escalated into a large scale conflict that dragged several other races in as it went on. Though by the end of the century the last of the Rebel forces were defeated by the UNSC, it left both humanity and their allies in a greatly weakened state.
