So we know that Jabba the Hutt was leader of a vast criminal empire. In fact, according to Legends canon, Jabba's organization was apparently the Outer Rim equivalent of Black Sun, or nearly so. He was certainly powerful enough that Black Sun's leader, Prince Xizor, considered Jabba to be one of the only two individuals that posed a threat to his position (the other being Darth Vader). We also know that Hutts in general respect wealth & power, with such things determining a Hutt's status within the social ranks of Hutt society.
What we don't know, however, was where Jabba fit within Hutt society. Given his wealth, power, and influence, you'd think Jabba would be fairly high up the social ladder. However, Jabba resides on Tattooine, which is quite some distance from Nal Hutta (the Hutt homeworld), and does not appear to be one of the ruling Hutts in their society. In fact, the only Hutts we see Jabba interacting with are Durga - the other Hutt on Tattooine - and Jabba's uncle/aunt on Coruscant. In both cases, the other Hutts defer to Jabba. However, in both cases, the other Hutt falls within Jabba's personal sphere of influence.
What exactly is Jabba's position/rank within Hutt society, and is he considered any kind of leader or official figure to the other Hutts?
