Jiramma was a Hutt family, with their operations centered on Nar Shaddaa. One notable individual was Darga Jiramma Mionne, a member of this clan.
Jiramma belonged to the group known as the Clans of the Ancients. These were the most prestigious Hutt kajidics, those able to demonstrate a lineage extending back to the Hutt homeworld of Varl. This status granted them a position on the Hutt Grand Council.
Kor Jiramma, situated in the Bootana Hutta area of Hutt Space, functioned as the clan's throneworld. Their main operational hub, however, was the moon Nar Shaddaa. Furthermore, they exerted influence over the planets Cato Neimoidia and Sleheyron, in addition to Kwenn Space Station.
During the time of the Galactic Civil War, Jiramma maintained strong connections with the Galactic Empire. Outside of their Imperial dealings, they often collaborated with the Vanderijar kajidic.
