Las Brujas del Mar (Witches of the Sea) began with a private group on Facebook. Discussing feminist topics, violence often came up, and women were asking for help. After the first time they helped remove a woman from a violent home, the organization began to take shape.[5]
Arussi Unda helped organize the National Women's Strike on March 9, 2020, in Mexico, to protest and raise awareness of the increasing violence faced by women across the country.[6][7][8] This occurred the day after International Women's Day.[9]
Unda was on the list of the BBC's 100 Women announced on 23 November 2020.[10]
