What was it about 1968 that shook the foundations of American life, defining the end of one generation and the beginning of another?
Was it the Tet Offensive or the My Lai massacre? Was it the assassinations of Martin Luther King and Robert F. Kennedy, which left millions grieving and disillusioned? How about the sight of Tommie Smith and John Carlos raising their fists at the Summer Olympics in Mexico City? The answer is all of the above, and more.
Here are some images from March of that explosive and significant year.
