20th century economic and political developments presented South African women with both new obstacles and new opportunities to wield influence. For example, labor force requirements in cities and mining areas have often drawn men away from their homes for months at a time, and, as a result, women have borne many traditionally male responsibilities in the village and home. Women have had to guarantee the day-to-day survival of their families and to carry out financial and legal transactions that otherwise would have been reserved for men.
