What is an example of a nonviolent unsuccessful method?

An example of a nonviolent unsuccessful method is the 1989 Tiananmen Square protests in China. Despite the peaceful demonstrations advocating for democratic reforms and greater freedoms, the movement was met with a violent crackdown by the government. The protesters' calls for change were ultimately suppressed, and the government maintained its authoritarian control, highlighting the limitations of nonviolent resistance in the face of state violence.
