After the 1979 Iranian Islamic Revolution, hijab was made compulsory in stages. In 1980 it was made mandatory in government and public offices, and in 1983 it became mandatory for all women (including non-Muslims and non-citizens). From 2017 to 2019 protests were held against compulsory hijab with authorities announcing the arrests of 29 women.&lt;ref name="RFE/RL-13-5-2021"&gt;&lt;/ref&gt;
