Civil rights movements are a worldwide series of political movements for equality before the law, that peaked in the 1960s. In many situations they have been characterized by nonviolent protests, or have taken the form of campaigns of civil resistance aimed at achieving change through nonviolent forms of resistance. In some situations, they have been accompanied, or followed, by civil unrest and armed rebellion. The process has been long and tenuous in many countries, and many of these movements did not, or have yet to, fully achieve their goals, although the efforts of these movements have led to improvements in the legal rights of some previously oppressed groups of people, in some places.
