The 1960s were a "busy" decade in American history, so there are many interesting topics you could address. In fact, a very good essay would discuss how these topics were interrelated. Some potential topics include:
- The Civil Rights Movement. The movement did not begin in the Sixties, but it achieved its greatest successes in this decade. You might consider, in addition to more mainstream topics, how the movement fragmented as it evolved into movements for Black Power and other demands.
- War in Vietnam. This conflict helped shape everything political and social that was changing in the Sixties and scarred the American psyche like few other events in our history.
- The developing "counterculture" and politicization of youth. Across the nation, young people rejected the values and culture of the previous generation. This movement resonated with politics, on college campuses, and in music and the arts.
- Politics. The Sixties witnessed a seismic shift in national politics, with the Republican Party shattering Democratic control of the South, partially in response to many of the developments discussed above.
Any of these topics, or a combination of them, should make for an interesting essay.
