Bursa–Gungan war

It was believed that long before the arrival of Humans on the planet Naboo around 3900 BBY, the planet's native sentients, the Gungans, rallied for war against bursas, a violent semi-sentient species that attacked Gungan settlements on a regular basis. To combat the threat, the Gungans developed military technology and created a Gungan Grand Army that supposedly drove the bursas to extinction. Gungan society became more militaristic and tribal as a result of the war with the bursas, and they continued to maintain the Gungan Grand Army in the following years, even during peacetime. Bursas still played a role in the war between the Gungan tribes, which ended in 3000 BBY, and they were later captured and bred for export by members of the Amaran species.
