Ziro the Hutt going before the Hutt Grand Council in the episode "Hunt for Ziro"

The Clone Wars did for Star Wars canon what the movies simply couldn't do even in six films because the universe is so huge. For me, one of the more intriguing characters was always Jabba the Hutt. I always wanted an answer to the question: where did the Hutts come from? To know this requires a little information borrowed from the Clone Wars Wiki:

The Hutt Grand Council is the governing body of the Hutts. It convenes on the planet Nal Hutta, the capital of Hutt Space. Who knew, right? I never thought the Hutts would have their own planet or even a capital city. Anyway, the council arbitrates disagreements and makes the laws that the Hutts live by and is regarded by other races as "fair" in their rulings.

One member of each clan represents their family's position and criminal enterprises in the Hutt Council. However, not all Hutt clans are allowed a seat on the council, as each clan has to trace their lineage to the Hutt's old homeworld "Varl" to win a seat. During the Clone Wars, the five members of the Hutt Council are Jabba, Gorga, Arok, Oruba, and Marlo. Watch the clip below and see how good the animation really is.

So just like the Jedi High Council, the Hutts had one too...albeit far less athletic. You see the Hutt Council in "Hunt for Ziro," which is the ninth episode of the third season, and again in "Eminence," which is the fourteenth episode of the fifth (and last) season.
