The 1960s saw many social movements emerge that challenged the status quo. The decade was defined by the civil rights movement and Black Power movement's fight for racial equality, the anti-war movement and protests against US involvement in Vietnam, the women's liberation movement's battle for gender equality and women's rights, and the rise of the counterculture that promoted sexual freedom, psychedelic drugs, and environmentalism. These diverse movements reflected the era's rising social consciousness and desire for political and social change.
