Other feminist movements and " calls to action " have arisen from the fourth wave . One is the " HeForShe " campaign which originated from Emma Watson 's viral UN Women speech in 2014 and her subsequent activism . Several other incidents have galvanized the movement , including the Delhi gang rape ( India , 2012 ) , Jimmy Savile allegations ( UK , 2012 ) , Bill Cosby sexual assault cases ( US , 2014 ) , Isla Vista killings ( US , 2014 ) , trial of Jian Ghomeshi ( Canada , 2016 ) , Harvey Weinstein allegations ( US , 2017 ) and subsequent Me Too movement and Weinstein effect , the Westminster sexual scandals ( worldwide and UK , 2017 ) , and the La Manada gang rape case in Spain ( 2018 )
