The Tambors were a lineage of Skakoans originating from the planetary body known as Skako Minor, and their members included Wat Tambor, his offspring Wat Tambor II, and Jul Tambor, who was the son of Tambor II. Serving as the foreman for the Techno Union, Wat Tambor's life was ended when he was killed by the Sith Lord Darth Vader as the Clone Wars drew to a close. Later, Wat Tambor II also met his death at the hands of Vader, during the Galactic Empire's seizure of Skako Minor. At a later time, Jul, accompanied by other Skakoans, found themselves banished from Skako Minor due to their dissent against the Skakoan Council, leading them to establish a presence on the planet Brentaal IV. Sometime between the years 3 ABY and 4 ABY, Jul spearheaded an uprising with the goal of wresting control of Skako Minor back from the Skakoan Council.
