Shmi Skywalker

Shmi Skywalker is the mother of Anakin Skywalker.

About her
Formerly a slave on Tatooine, Shmi is the mother of Emperor Anakin Skywalker and thus the Queen mother of the Empire. She is also the mother-in-law to Padme Skywalker and the grandmother to Luke and Leia Skywalker. She was freed from slavery by Anakin using both the prize money from his race win and the money he got from selling his podracer. She, like her son, is descended from Revan and Bastila Shan.
