Factional warfare became a part of EVE Online in the Empyrean Age expansion, which ushered in a time of backstory-driven militia conflict for players aligned with one of the four races of New Eden. What promised to be a new avenue for EVE's roleplaying community ended up being inaccessible to roleplaying alliances. CCP stipulated that alliances cannot enlist with factional militias, as their sheer numbers could streamroll their opposition and create overwhelming odds for the disadvantaged side in the conflict.
The only recourse EVE's alliances have is to form splinter corporations outside of the alliance, for the sole purpose of allying with a given racial faction. That is, until recently. An article from ISD Magnus Balteus, one of EVE Online's in-game reporters, states the Star Fraction alliance "has openly declared war on corporations that have joined the Caldari milita; the State Protectorate. For over a month, Star Fraction has been selectively targeting the corporations of fleet commanders in the Caldari militia."
