Nigel Cliff, author of “The Shakespeare Riots,” discusses an 1849 feud in New York that turned into a full-scale riot of thousands that killed 25 people. With Bardolatry at its height, the struggle centered on the question of who “owned” Shakespeare. Cliff spoke at the Harry Ransom Center, a humanities research library and museum at The University of Texas at Austin, on April 14, 2016.
