Vuul served as the President of the world Bri'ahl throughout the time of the Clone Wars. His choice to align with the Galactic Republic came about following a visit to his planet by Senator Amidala.
President Vuul of Bri'ahl's desire for an alliance with the Galactic Republic in the Clone Wars stirred up controversy among his people. Certain pro-Separatist members of his family plotted to assassinate both Vuul and Senator Padmé Amidala of Naboo before the agreement could be finalized. However, this assassination attempt was inadvertently thwarted by the droids R2-D2 and C-3PO. After this event, Vuul reaffirmed his dedication to the Republic.
