Why is "History of the United States (1964–1980)" trending?

Wikipedia Overview

The history of the United States from 1964 to 1980 includes the climax and end of the Civil Rights Movement; the escalation and ending of the Vietnam War; the drama of a generational revolt with its sexual freedoms and use of drugs; and the continuation of the Cold War, with its Space Race to put a man on the Moon. The economy was prosperous and expanding until the Recession of 1969–1970, then faltered under new foreign competition and the 1973 oil crisis. American society was polarized by the ultimately futile war and by antiwar and antidraft protests, as well as by the shocking Watergate affair, which revealed corruption and gross misconduct at the highest level of government. By 1980 and the seizure of the American Embassy in Iran, including a failed rescue attempt by U.S. armed forces, there was a growing sense of national malaise.
