Chewbacca is a Wookie born on Kashyyyk 200 years before the Battle of Yavin. Chewbacca fought in the Clone Wars on the Republic's side, but when The Galactic Empire was formed he was turned into a slave. Years later, Han saved him from slavery and since Chewbacca owed him a life debt, he decided to accompany Han on his smuggling adventures.
Chewbacca and Han eventually became as close as brothers. Their bond only became stronger after they became members of the Alliance to Restore the Republic. After the end of the Galactic Civil War and liberation of Kashyyyk from Imperial control in 5 ABY, Chewbacca gleefully introduced Han to his wife & son. Han in turn vowed that he wanted Chewbacca to be a part of his own family life as well and already began considering him the godfather of his unborn son.
