Chewbacca is Solo's best friend. Both Han and Chewie can be found in Mos Eisley's bars frequently.
He and Chewbacca were hired by Obi-Wan Kenobi and Luke Skywalker on Tatooine to provide them transport to Alderaan on the Millennium Falcon, but those plans soon went awry. Initially only aiding the Rebellion to pay off his debt to Jabba, Han shelved much of his cynicism, proved his heroism and became a Rebel leader.
After the events of the sixth episode of Star Wars, Return of The Jedi, he also became the husband of Leia and the father of Kylo Ren a.k.a. Ben Solo. During the seventh episode, he was killed by his son.
