Yes, I agree with the statement that women's organizations played a critical role in civil resistance in South Africa from 1950 to the 1990s. Women's organizations were instrumental in the struggle against apartheid, and their involvement in civil protest was crucial in ensuring the eventual demise of apartheid.
One of the most well-known women's organizations in South Africa was the Federation of South African Women (FSAW), which was formed in 1954. The FSAW was an umbrella organization that brought together women from different racial and ethnic groups to fight against apartheid. The FSAW organized a number of protests and campaigns, including the Women's March on August 9, 1956, which saw 20,000 women of all races march to the Union Buildings in Pretoria to protest against the pass laws.
Another important organization was the Black Sash, which was formed in 1955. The Black Sash was a white women's organization that initially focused on protesting against the removal of colored voters from the voters' roll. However, the organization later expanded its focus to include opposition to apartheid policies in general. The Black Sash organized a number of protests and campaigns, including the Passive Resistance Campaign of 1960, which saw thousands of people, including many women, arrested for refusing to carry passes.
Other women's organizations that played a role in the struggle against apartheid included the Women's National Coalition, the Natal Organization of Women, and the Azanian Women's Organization. These organizations were involved in a range of activities, including protests, strikes, and boycotts.
Women's organizations were also involved in supporting the families of political prisoners and activists. For example, the Detainees' Parents Support Committee, which was formed in 1981, provided support to the families of people who had been detained without trial.
In conclusion, women's organizations played a critical role in civil resistance in South Africa from 1950 to the 1990s. These organizations were instrumental in organizing protests, campaigns, and other forms of resistance against apartheid. Without the active participation of women's organizations, the eventual demise of apartheid may not have been possible.
