Chewbacca (or "Chewie", as he was known by his friends) was a legendary Wookiee from Kashyyyk and co-pilot of Han Solo's ship, the Millennium Falcon. He was the son of Attichitcuk, the husband of Mallatobuck, and the father of Lumpawaroo. Chewbacca carried with him the name of an ancient Wookiee hero, the great Bacca, first of the great chieftains of Kashyyyk, and the creator of a sword that denoted leadership among the Wookiees. This name placed Chewbacca in a noble lineage, which was further supported by his role in the Battle of Kashyyyk during the Clone Wars and during the Galactic Civil War.
Chewbacca was a wise, sophisticated being of great strength and loyalty. As technologically savvy as the brightest Academy graduate, he was also a skilled mechanic. Chewbacca, like many Wookiees, was able to understand Basic, but he could not speak it due to his species's vocal structure. He instead spoke Shyriiwook, the main Wookiee language, composed largely of growls and grunts, to his non-Wookiee companions who typically replied in Basic.
He later died during the Yuuzhan Vong War. He lived with his family in Rwookrrorro. Chewie and his father were responsible for the creation of many villages on Kashyyyk in the decades before the Battle of Naboo and both of them participated in the colonization of Alaris Prime, where they faced the Trade Federation for control of the moon. Notably, during this time Chewbacca had his first recorded encounter with Jedi—as Qui-Gon Jinn and Obi-Wan Kenobi had been assigned by the Galactic Republic to end the conflict on Alaris Prime. Under Jinn's tutelage, Chewbacca was able to successfully lead the colony to military and economic success.
However, for all of Chewie's success, rivalries between different Wookiee families continued to plague Kashyyyk. Tvrrdko, the father of Tojjevvuk continued to seek revenge for the death of his son, but waited for the ideal moment. Tvrrdko's wrath had caused Chewbacca to stay away from his homeworld, but the Confederate threat to Kashyyyk forced him to return. The clones and their Jedi Generals recruited many of the Wookiees, and Chewbacca became a leading member of the Wookiee resistance to the Confederacy of Independent Systems. During the first year of the Clone Wars, Chewbacca was considered to be one of the Wookiee King Grakchawwaa's greatest warriors. He led the Jedi to the traitor Quaagan, who was conspiring with Confederate commander Asajj Ventress.
