In what ways did the lives of disenfranchised Americans, specifically African Americans, women, and American Indians, change from 1840 to 1900? For each group, you need to explain 3 significant events or moments from 1840 to 1900 that altered the status of that group, and explain why each event was significant to changing their lives. At the beginning of the 20th century (e.g. the 1900s), what major problems were still of concern for each of these disenfranchised groups (meaning, what problems existed that made them into second-class citizens)? Give at least 2 concerns for each group.
