House Jaddo was a respected Centauri house and a long time ally of House Mollari.
By 2259, the house had begun to make many enemies in political circles particularly that of Lord Refa and his supporters, due to its apparently anti-expansionist standpoint. Soon Refa arranged for a resolution to be brought before the Centaurum declaring it to be traitorous. Its leader, Urza Jaddo was forced to seek help from House Mollari but unfortunately it was allied with Refa. Urza challenged Londo Mollari to the Morago in order to save the honor of the house. By sacrificing himself, Jaddo made it possible for the surviving members of House Jaddo to be honourably taken in by House Mollari.[1]
