How did the role of women change in the 19th century?

The role of women drastically changed in the late 19th century because they started working while their husbands were sent to the war abroad.

Explanation:

Early 19th Century - Women were commonly homemakers before the World War I. They took the roles of a mother, cook and a wife. People also relied on them to take care of children for it was common to have big families during those times. If they ever had jobs, it was becoming a lowly servant of a rich or noble family.

Late 19th Century - Since the World War I broke out, many men were sent abroad to fight. This left the women to fill in the shoes of their husbands. They started working and took the roles of a nurse who takes care of those wounded in the war or factory workers.

This is how the role of women changed in the 19th century.
