HETAIRA started in 1995, on the initiative of a group of women, some engaged in prostitution, others not.     
At that time, there was a need to organise, to combat the social stigma attached to sex workers and to claim their rights, for example, to work in peace, to organise themselves, to join trade unions, etc., and to make sure that they had the same rights as other women.     

This struggle continues until today. HETAIRA is engaged in Spain and in Europe in campaigns and activities for the human rights of sex workers.
