Women's Rights Revolution
Women in 1912 had virtually no power whatsoever. They couldn't vote, had no legal rights, and were literally seen as property of their fathers or husbands. Sheila's childish language and dependence on male approval at the play's start perfectly captures this suffocating reality.
The patriarchal society expected women to be silent housewives and baby-makers - nothing more. Even the small victories, like the 1882 Married Women's Property Act letting women keep their own belongings, only helped the tiny minority who actually owned anything.
By 1945, everything had transformed dramatically. Women's crucial role in WWII proved they were valuable beyond domestic duties. The women's suffrage movement had fought hard (sometimes violently) for political rights, achieving equal voting rights in 1928.
Priestley uses this historical shift brilliantly through Sheila's character development. Her journey from disenfranchised daughter to confident young woman mirrors how women gained political voice and social power. Meanwhile, Eva's treatment shows how being both working-class and female made women doubly vulnerable to abuse.
Analysis Tip: Eva's lack of voice contrasts sharply with Sheila finding hers - this represents the journey from 1912's oppression to 1945's empowerment.
