It’s not because the word “wars” can be found in the saga’s title that the people of the galaxy never made time for a proper holiday or celebration. Holidays were a part of everyday life to the average Barada or Wedge, if they were lucky enough to live in freedom or on a planet where government didn’t suppress celebrations. But then again, even the Hutts gave their slaves a holiday that “rewarded” their servants with festivities.
The heroes of the saga took part in several celebrations that happened after important victories over the forces of evil. When the Trade Federation was defeated, Queen Amidala handed Boss Rugor Nass the Globe of Peace in the city of Theed, and united the Gungans and the Naboo after many years of uneasy relationships. After the destruction of the Death Star Princess Leia Organa bestowed Luke Skywalker and Han Solo, the new poster boys of the Rebel Alliance, with Medals of Bravery (which was later also given to Chewbacca). The biggest celebration probably took place after the second Death Star had been destroyed and Emperor Palpatine had been killed. Not just on Endor, but throughout the galaxy, supporters of the Rebel Alliance and the ideals of the Republic and democracy, cheered, danced, and toppled statues.
