The anti male-guardianship campaign is an ongoing campaign by Saudi women against the requirement to obtain permission from their male guardian for activities such as getting a job, travelling internationally or getting married. Wajeha al-Huwaider deliberately tried to travel internationally without male guardianship permission in 2009 and encouraged other women to do likewise. Women activists wrote a letter to the Saudi Minister of Labor and brought media attention to the issue in 2011. A 14,000-signature petition was given to royal authorities by Aziza al-Yousef in 2016 following a Human Rights Watch report on male guardianship. A crackdown against the activists took place in mid-May 2018, with 13 arrests as of 22 May 2018. Several of the women remained in prison as of December 2018. Som
