When Americans talk about the Sixties, they're really talking about 1968.

  • In Vietnam, more American troops were in-country than any other year of the war.
  • The assassinations of Rev. Martin Luther King Jr. and Robert F. Kennedy shocked the country and forever changed the political and social movements they led.
  • The Beatles visited Maharishi Mahesh Yogi's transcendental mediation camp and came back to create their iconic White Album.
  • Some of Hollywood's most iconic films ever –  including "2001: A Space Odyssey," "Rosemary's Baby," "Barbarella," "Funny Girl" and "Planet of the Apes"  – all battled for bucks at the box office.
  • And movements of peace and protest commanded the streets of American cities in every state.

See some of the unforgettable moments and images that defined not only the year but an entire decade – and in many cases, the nation – in this photographic look-back at the year 1968.
