From Nelson Mandela to Google Glass, David Bowie to Yayoi Kusama—a look at this year's top headlines

The week of 28 August 2013 marked the 50th anniversary of Dr Martin Luther King, Jr.’s world-changing speech addressing racial discrimination, attended by around 250,000 people in Washington, DC. The Boston Globe’s expansive photo collection captures some of the most striking images from both his speech and the civil rights movement. The remarkable aerial view of the National Mall on that historic day is especially telling of the magnitude of support and political activity, while photos of children being taken to jail for protesting racial segregation in schools reflect the over-zealous police force of Birmingham, Alabama. The photos illustrate both the progress inspired by Dr King’s leadership, as well as the strides we still have to make toward total equality.
