Attack on the Galactic Senate

In 12,978 BBY, during the Hutt War, the Hutt Empire carried out an attack on the Galactic Senate. Hutt Emperor Tusa Ujalli Hai addressed the Galactic Senate using sabotaged speakers, causing a loud noise to emanate from it that was so loud it put any Human who could hear it into a vegetative or near-vegetative state. The attack devastated the Senate, as it removed most of its members from service.
