The Vietnam era was marked by student anti-war protests and the counterculture movement. But in 1970 the "silent majority" organized the era's largest pro-war demonstration, simultaneously protesting against President Nixon's Vietnam War policies and "hippies and yippies everywhere."

Mike Tyson, the so-called "Baddest Man on the Planet," was known for his antics, in and out of the ring, as much as he was known for his boxing ability. While Tyson's sole fight in the nation's capital isn't his most well-known fight, the bout was certainly historic.

In February 1979, thousands of farmers from across the country — and their tractors — barreled into Washington to protest in favor of agriculture policy reform. They snarled traffic for several weeks, frustrating commuters. But public opinion began to shift when an unexpected blizzard buried the city under two feet of snow and the protesters took it upon themselves to plow city streets and ferry doctors and nurses to work.

The first National Christmas Tree lighting ceremony took place in 1923. The ceremony was intended to foster a sense of national unity around the Holiday season, but 1973 was different. President Richard Nixon, embroiled in the Watergate scandal and dealing with an energy crisis, used the ceremony as a platform for political theater. As the President talked up his administration's achievements and legislative agenda for the coming year, an impromptu political rally in support of the President broke out.

Not only were the President's remarks different in nature, the tree was as well. As Americans across the country had to tighten their belts with regards to energy, the energy crisis prompted organizers to significantly reduce the number of lights upon the tree itself as well as begin a new tradition of using a living, rather than cut, National Christmas Tree.
