The resistance movement known as The Eleven, alternatively referred to as the Bellassan Eleven, originated on the world of Bellassa. It was established by Ferus Olin and Roan Lands as a means of opposing the Galactic Empire. Their formation occurred soon after the Empire overthrew the kind Bellassan administration and implemented military control. The Eleven, along with their allied forces, spearheaded a rebellion targeting the new Imperial authority. However, the Empire's strength was insurmountable, resulting in Roan's capture and the demise of numerous individuals.
While searching for Ferus, a former Jedi, Obi-Wan Kenobi encountered the surviving members of The Eleven who had evaded capture by the Empire.
After Ferus fled Bellassa alongside Kenobi, support for The Eleven increased on Bellassa, and within a few months, its ranks had swelled by several thousand.
