Septima Poinsette (she acquired the Clark surname when she married and kept it after becoming a widow), was an African-American educator and civil rights activist born in Charleston, South Carolina, in 1898. Her parents were slaves and they worked hard to get her to receive education in a school where African Americans were accepted.
However, at the time Septima lived, racial segregation was on the rise despite the fact that slavery had already been abolished. In addition, she experienced discrimination when, after studying to become a teacher, she was denied to work in her hometown because it was prohibited for people of African descent.
It was there where she began her struggle for civil rights and the elimination of racial discrimination.

So, she fought hard during her life for equality and for teaching black people to defend themselves civically against the laws that prevented them from voting and doing other activities.
