There’s a reason or two why women depicted in nineteenth century novels have only one thing on their minds: marriage. They had nothing else to do and marriage was the most important event in their lives, determining the rest of their future.
As a historical writer, you have to be aware of the restrictions on women during your era and in your place. Could they go out without a chaperone? Were they allowed to study anything?
You can be sure of one thing: restrictions existed. I’m glad I’m alive now and not earlier. I’m glad I live in the country I live in, rather than one in which women are still restricted.
