From Vietnam to Gaza, Harvard Yard has served as a historic stage for student protests and political activism.

From Seattle and Austin to Chicago and Washington, D.C., marchers have chanted slogans, carried signs against ICE, and snarled traffic through downtown avenues and outside federal offices.
