Jabba Desilijic Tiure - better known as Jabba the Hutt - is a notorious crime lord in the Star Wars franchise. As head of the Desilijic crime family, he was involved in some way with most criminal activity across the galaxy. He even held a considerable level of influence over the Galactic Republic, as shown during the Clone Wars when the Jedi negotiated with him for the use of his syndicate's trade routes. His role in the films has been minor for the most part, though he made an enemy of Luke Skywalker in Return Of The Jedi when he refused to negotiate over Han Solo, who at the time was frozen in carbonite and had been placed in the Hutt's palace as a decoration.
Death
After Jabba's pet Rancor had been killed by Luke Skywalker, the Hutt demanded that Luke and his friends be punished by being cast into the Pit of Carkoon, the nesting place of the Sarlacc, a monster that digested its prey over a thousand-year period. Jabba's gang took Luke, Han and Chewbacca out to the Dune Sea and attempted to drop Luke into the pit, but Luke resisted and a battle broke out. Aboard his sail barge, Jabba kept Princess Leia Organa at his side on a chain, but in the confusion R2-D2 freed Leia and she used her chain to strangle Jabba to death.
