From 1820 to 1848 and again from 1865 to 1898

Your question is rather vague by just giving dates ... but I think I know what you might be looking for here.  During the "antebellum" (before the Civil War) years and again in the years after the Civil War, there were strong movements by social activists that went against how society wanted to keep women and African Americans in "their place."  Social reformers thought that the place assigned to women or to blacks was not at all right.  They put forward better ideas of how black Americans and female citizens should have equal status with whites and with men in regard to political, social, and economic rights.  
The activist movements from 1820 to 1848 and again from 1865 to 1898 didn't achieve all their goals in that time period, but they began to advance the causes of civil rights for blacks and women -- both movements which would continue into the 20th century.

Not sure if it’s within 12 months, but you could talk about the spreading of alt-right hate speech and whether that is covered by the right of freedom of speech? or, cover how during the midterm elections in some states many native american populations were declined to vote because they didn’t have the proper id, despite being citizens? also, the death of that journalist last month, who spoke freely and reported about the saudi government and how corrupted it is and was killed because of that (lack of free press/speech). just some ideas for this prompt, i hope at least one of them : )

Idk what state you live in bu i’m assuming it’s math/technology because that’s what we’ve been taught in georgia haha
