As a result of the 1960 sharpeville demonstration, Desmond Tutu began to believe that only armed rebellion would bring an end to apartheid.
Back then, the fight against apartheid. But after the massacre i Sharpeville, the civil rights activists started to lean to armed rebellion since they felt that non-violence movements were completely useless
hope this helps
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.
it was to address the problems of the weak central government the exist under the articles of confederation
