The Alderaan Conference on the Clone War Refugee Crisis was led by Senators Padmé Amidala of Naboo and Bail Organa of Alderaan. It was called to address the growing concern over refugees generated by the galactic conflict known as the Clone Wars. It was hosted on the peaceful world of Alderaan by Organa, the planet's Viceroy. It was at the conference that bounty hunter Aurra Sing chose to assassinate Senator Amidala. Sing was hired by Ziro Desilijic Tiure, who wanted revenge for his Republic imprisonment, but her assassination attempt was thwarted by Padawan Ahsoka Tano and the senator herself.
