Mimban, also known as Circarpous V, "was" a swamp planet that was the homework of several intelligent species, including Mimbanese.
Mimban was rich-in meneral, attracting mining interests.
During the Clone Wars, the MudJumpers of the 224th Division helped the Mimbanese to repel the Separatist Droid Army.
In the Emperial era, ironically the 224th came to Mimban as subjugation forces for the Emperial Mining operations.
