The single most important change in the 1960’s in my opinion is the social change that arose due to the Civil Rights Movement. Starting with the Greensboro sit-in, the spark ignited a change. The blacks not only fought for termination of racial segregation, but also for social equality. Although it had a rough start with violence from the authority and the constant tension between the activists and the government, it served as a turning point in the American History.
With many organizations established, different races began to unite and protested in different means. Most activists practiced nonviolence ways of demonstration under leaders like Martin Luther King Jr. and Rosa Parks. The Civil Rights Movement re-established the meaning of Constitution for some group of people. It served as a turning point in the history of African American as they became more accepted and gained their freedom.
I agree with your opinion that it is a very important change in the 1960’s because it actually changed the whole society of America and it’s very interesting that even these days there are few hidden racism and the civil rights movement is still going on these days.
