1 5M Discuss the role of women in World War I and World War II. 5 marks · 50 words

Model Answer

WWI mobilised 800,000 British women in factories, transport, and nursing — directly replacing men at the front. WWII expanded this globally: the USSR deployed 800,000+ women as frontline soldiers ("Night Witches" bomber squadrons); the USA's "Rosie the Riveter" symbolised women in defence manufacturing. War service accelerated women's suffrage — Britain granted the vote in 1918, France in 1944, transforming gender roles permanently.
