The Gungan Grand Army was a large Gungan army on the planet Naboo. It was formed around 3000 BBY by Boss Gallo during the War of the Gungan tribes to defeat Boss Rogoe. During its history, it fought the Gungan–Naboo War with the Naboo. In 32 BBY, the Trade Federation invaded Naboo, enslaving the Naboo people and driving the Gungans out of Otoh Gunga.
