The 2017 Berkeley protests were a series of protests and clashes between organized groups that occurred in the city of Berkeley, California, in the vicinity of the University of California campus. Violence occurred predominantly between protesters opposed to then-President Donald Trump, including activists such as antifa groups and socialists; and pro-Trump groups such as Republican, alt-lite, alt-right, neo-Nazis, and white nationalists. The majority of the participants on both sides were people who wanted to listen to the speakers peacefully, and peaceful protesters against the speakers.
