The Jyhad is the "eternal struggle" for dominance between Methuselahs (ancient Kindred, possibly including the Inconnu) and the surviving Antediluvians. It is a subtle conflict which is fought in the everynight interactions of younger vampires, most of whom are entirely unaware they are being controlled and used as pawns. The Camarilla officially denies the reality of the Jyhad, as they do the existence of the Antediluvians. The Sabbat, on the other hand, exists largely to fight against the Jyhad and its players, especially the Antediluvians.
