The Ethical movement is an ethical, educational, and religious movement established in 1877 by the academic Felix Adler (1851–1933). In an effort to develop humanist codes of behavior, the Ethical movement emerged from the moral traditions of the secular societies of Europe and the secular society of the 19th-century United States. In practice, the Ethical movement organized themselves as two types of organization: (i) a secular humanist movement and (ii) a predominantly moral movement with a religious approach.

Humanists International is an international non-governmental organisation championing secularism and human rights, motivated by secular humanist values. Founded in Amsterdam in 1952, it is an umbrella organisation made up of more than 160 secular humanist, atheist, rationalist, agnostic, skeptic, freethought and Ethical Culture organisations from over 80 countries.
