In what ways did educational opportunities change for minorities and women in this era?

We are going to assume the era you are referring to is after the American Civil War. This was a time when women started to demand better opportunities in general terms, including education for women. American women wanted to have a better role in society, not only as mothers in the family environment.

In that time and before the Civil War, the expansion of education including higher education opportunities for women was widely opposed in most parts of the country. This made women seek education or better education in other states or started to raise their voices to get the education they deserved.
