Grizmallti–Gungan war

Eventually, the two species signed a peace treaty in which both sides agreed to avoid each other, while maintaining an intense distrust. As a result of the conflict, the Humans reinvented their culture to focus on peace, art, and knowledge, also calling themselves the Naboo. The animosity between the species persisted for generations until they united to repel the Trade Federation in the Invasion of Naboo in 32 BBY.

The war between the Gungans and the Humans was first mentioned in Secrets of Naboo, a 2001 sourcebook for the Wizards of the Coast Star Wars Roleplaying Game. A variety of sources suggest that no war between the Gungans and the Humans ever took place, including a claim made by Padmé Amidala in Star Wars Episode I The Phantom Menace that both societies had lived in peace.

Another source to refute the existence of the war was the DataBank in the 2001 LucasArts video game Star Wars: Galactic Battlegrounds. During the game's development, early levels of the Gungan campaign were intended to involve a conflict between the Gungan Boss Gallo and Human Naboo tyrants, but the creative team, including level designer Stephen J. McManus, was informed that canonically, no war between the two had taken place. McManus was forced to redesign the campaign to become a war between Gungans.

In 2004, Star Wars Galaxies: Jump to Lightspeed: Prima Official Game Guide stated that the Humans and Gungans did not attack each other despite their opposition, but acknowledged that armed clashes were rare. 2008's Knights of the Old Republic Campaign Guide also refuted the existence of the war, describing the Gungans as "unperturbed" by the arrival of Humans.
