Tuesday's march traveled three miles from downtown Tunis to the Menzah stadium, with chanting in multiple languages and representation from a wide variety of movements from the Tunisian Popular Front to Catholic NGOs to ATTAC, a movement challenging global finance. At the Menzah stadium, an opening ceremony began at 7:30 pm with female social movement leaders from Palestine, South Africa, Tunisia, and the US taking the stage, including Besma Khalfaoui, widow of Tunisian opposition leader Chokri Belaïd, who was assassinated last month. According to Forum organizers, only women were chosen for the opening as a response to the rise of conservative religious governments in the region as well as patriarchal systems around the world. "We decided this because women are the struggle in the region," said Hamouda Soubhi from Morocco, one of the organizing committee members. "They are struggling for parity, they are struggling for their rights. The new regimes want the constitutions to be more religious, and we want to take our stand against this."
